OT-camera batteries? Olympus C-3000
I was fortunate enough this week, to swap for a minty Olympus C-3000
Zoom digital camera with 128meg smart media. Friend of mine is upgrading to hip slick and cool wonder camera Having had some very elderly digital cameras...this thing blows me away. And its obsolete...chuckle...but is way way cool and will do EVERYTHING I need a camera to do for me. I didnt get any batteries with it..he uses nicads and kept them, So I loaded it up with fresh Alkalines..and got about 10 daylight pictures out of them....damn thats a battery hungry *******!!! So Ive been doing some research on digital camera batts this evening, along with chargers etc It would appear that everyone is pushing Nickle metal hydride rechargables. Which for me..is better..NIMH or NiCads? It may be weeks or longer before I need to take any pictures and am worried about the self discharge of the NiMH batts On the other hand..NiCads appear to be only 800mah at best, based on ebay descriptions On the gripping hand...NiMH appear to have over twice the amp hour rating..1800 is average for AAs, going up to 2500 mah Is this what I want? http://cgi.ebay.com/MAHA-MH-C204F-CHARGER-w-AA-Batteries-Kit-Brand-New_W0QQitemZ7600147921QQcategoryZ64349QQtcZphotoQ QcmdZViewItem Or do I want to buy nicads and a smart charger with a conditioner circuit? Any input would be appreciated. Also..anyone have one of these cameras AND the proper AC wall wart? I need to know the voltage and polarity. The manual I downloaded didnt have any specs Thanks Gunner "Pax Americana is a philosophy. Hardly an empire.

OT-camera batteries? Olympus C-3000
I use NiMH batteries in mine and often find them dead when I want to use the
camera because I go weeks between uses. The people I know that take pictures often recharge their batteries on a regular basis and so it's not a problem for them. Karl "Gunner" wrote in message ...

NIMH is what you require.............mine hold a charge for several
weeks, and there is not the memory effect you get with NICADS.

OT-camera batteries? Olympus C-3000
Hey Gunner,
10 pix doesn't seem good. My year-old plus Canon Powershot uses 4 of NiMH AA size rechargeable's, and lasts for some unknown number of pix, because it has never gone "flat" on me, and I have taken over 50 pix at a time in fairly rapid succession, admittedly with recently recharged cells. It has sat for weeks without use, and then taken over 20, many times, without a problem. Biggest power draw on these is to recharge the flash capacitors, so try to use the No Flash or "available light" only setting if you can, just to see if there is a dramatic difference. My Canon Users Manual lists either these NiMH or 4 Alkaline's as being acceptable. Couple of possibilities.......Unless you bought the best "name-brand" Alkaline's you did try at a place that sells LOTS of batteries, it's a good chance they were not up-to-snuff to start off, or that in fact one of the four was defective, or....from a friend you wouldn't want to have this happen....but it is possible that your friend was happy to pass along a well operating but somewhat battery hungry camera. Take care. Good Luck on it too. Post some pix!!!! Brian Lawson, Bothwell, Ontario.

Those things _seem_ awesome, 1/4 the size of comparable amp-hour lead-acid batteries and very fast recharge. (and 4 times the price Don't know if they'd be crap's worth of use for cameras, but the testing reports I've seen for other uses are impressive if they're not all pre-marketing hype. Experimenters claim things like; 85-minute recharge time from full discharge, 5000 charge cycles tried with 3000 being warrantable, good high-rate discharge characteristics. Haven't had much luck with Google searches as far as marketing status, etc. so far. |

OT-camera batteries? Olympus C-3000
I've bought batteries from these folks and been happy with them:
http://www.nicdlady.com/ http://www.batteriesamerica.com/ http://www.sterlingtek.com/index.html Nicadlady seems to be a bit more expensive, so I usually buy standard batteries like AA from BatteriesAmerica. I needed a new battery for my camera (non-standard) and SterlingTek had it at a good price. As others have said, NiMH is a good way to go, but you must have the right kind of charger or the batteries won't live very long.

On Sun, 19 Mar 2006 09:35:26 GMT, with neither quill nor qualm, Gunner
quickly quoth: I was fortunate enough this week, to swap for a minty Olympus C-3000 Zoom digital camera with 128meg smart media. Friend of mine is upgrading to hip slick and cool wonder camera Congrats. My sister has a Camedia and loves it. I'm happy with my Nikon Coolpix 995 digital with better macro capabilities. Having had some very elderly digital cameras...this thing blows me away. And its obsolete...chuckle...but is way way cool and will do EVERYTHING I need a camera to do for me. I didnt get any batteries with it..he uses nicads and kept them, So I loaded it up with fresh Alkalines..and got about 10 daylight pictures out of them....damn thats a battery hungry *******!!! Right, alkalines don't last worth a **** in digicams. I was warned away from them by the articles on www.pcphotoreview.com and www.imaging-resource.com . http://www.steves-digicams.com/c3000.html shows a CR-V3 lithium. Go with that. (Cha CHING! but worth it.) So Ive been doing some research on digital camera batts this evening, along with chargers etc It would appear that everyone is pushing Nickle metal hydride rechargables. NiMH is better technology, with longer life and better power curve. Which for me..is better..NIMH or NiCads? It may be weeks or longer before I need to take any pictures and am worried about the self discharge of the NiMH batts Nicads self-discharge nastily, too. My Nikon uses Li-ion batts. They cost me $35 a pop (OUCH!) but are good, long-life batts. On the other hand..NiCads appear to be only 800mah at best, based on ebay descriptions On the gripping hand...NiMH appear to have over twice the amp hour rating..1800 is average for AAs, going up to 2500 mah Ayieeeeeeeeeee! Sound the alarm, MOTIES ARE HERE! Is this what I want? http://cgi.ebay.com/MAHA-MH-C204F-CHARGER-w-AA-Batteries-Kit-Brand-New_W0QQitemZ7600147921QQcategoryZ64349QQtcZphotoQ QcmdZViewItem Or do I want to buy nicads and a smart charger with a conditioner circuit? NiMH or Li-ion, whatever is available. NiCad AA batts have a half life of about three seconds and a shelf life of a week. I _abhor_ the smaller NiCads! (Or did 20 years ago when I gave 'em up.) My NiCad portable power tool batteries last only 3 years or so but shelf life is extended from what I used to receive from the smaller cells. I use NiCad only when I'm forced into it. For S&G, make your own battery pack. Waist-pack the heavier job and cord it to the camera. My Nikon has an external power plug, does your Oly? How about AIR? http://www.zinc.org/zincuses/airbattery.html Oh, I forgot. You're on my kind of budget. Neevermind. Cheaper than Lithium is this NiMH pack, but you'll be recharging more often. Buy several spare sets of batts so you always have a charged set on hand when (not if) the current set goes dead. http://cgi.ebay.com/FOR-OLYMPUS-C-30...QQcmdZViewItem -- "I'm sick and tired of having to rearrange my life because of what the STUPIDEST people *might* do or how they *might* react." -- Bill Maher |

OT-camera batteries? Olympus C-3000
Many moons ago I had an Olympus D600-L digital
camera. You did good to get 10 pics out of alkaline batts. I don't recall getting that much service from them. Upon ejecting the spent batteries I found them to be quite warm. Them old digital cameras loved batteries. At the time Ni-cads were a great improvement. I don't recall their capacity and I don't think the Nimh batteies were available at that time. Later I did upgrade to the Nimh batts about 1200mha if I remember correctly and got even better service from them. Today I'm more impressed with the Lithium Ion batts that run my EOS 10d. I've shot for more than half a day on them things. Unfortunately, I'm pretty sure Lithium ion batts don't come in the sizes you require. Devonshire On the day of Sun, 19 Mar 2006 09:35:26 GMT...

The manual I downloaded didnt have any specs For digital cameras, unless there is a Lithium Ion battery available or you need long shelf life with no charging available, NiMH is the way to go. There are lithium AA batteries that also work nicely but they are hideously expensive and not rechargeable--these would be the choice if shelf life was more important than cost. The discharge curve for NiCD doesn't work nearly as well with digital cameras as does NiMH. Alkalines the same. Two links for batteries if you're into digital photography: http://www.thomasdistributing.com/ http://www.amondotech.com Note that Thomas Distributing has several rechargeable lithium CRV-3 batteries that should work in that camera, give about the same number of shots as NiMH and hold a charge much longer in storage. For your use this might be a better way to go. Downside is that they cost more. I believe they may have an external lithium ion battery pack that will work with it as well. They've also got a wall-wart purpose made for Olympus cameras--it's made by digipower, and you might want to check http://www.digipowersolutions.com to be sure of the part number--digipower also lists the voltages with the product description. -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

Gunner typed these letters: Also..anyone have one of these cameras AND the proper AC wall wart? I need to know the voltage and polarity. The manual I downloaded didnt have any specs The proper wall wart that was intended for my Olympus was too expensive so I made one. If your old Olympus is like mine it had an "odd" sized jack for the wall wart to plug in to on the camera. Oddly enough, Radio Shack had the correct plug for the jack. My Olympus D-600L was 6 volt (4 AA bats) On the camera the pin in the jack is shown to be positive. I found that a 1000mA wall wart was not quite enough to run a D-600L. I recall hooking a amp meter to the thing and seeing it draw to the tune of about 1200mA. Which explains why the alkaline batts wouldn't last. Your camera maybe different, it's a bit newer than the Olympus that I had. The largest smart meda card I could use was 8mb. Later models would take up to a 64mb card. Would you believe I gave like $400 for this camera refurbished? It retailed for like $1200 when it came out. This was maybe 8 to 10 years ago. Devonshire |

First example of thousands of hits for "aa batteries charger" on ebay. I often find sales on 4 Nimh AA bats and charger for $8-$10 at Walleyworld or camera stores. I have 5 sets of 4. Forget nicads and other chesestry is too expensive. |

I have a couple of sets of RayOVac 15 Minute NIMH AA and AAA rechargeables and like them a lot. The AAs are 2000 mAh. I use the erratically and they hold a charge a long time - at least a couple of months. The batteries and charger are available at Wal Mart. Radio Shack rebranded the charger and the batteries, but they're available there also, but at a higher cost than Wal Mart. It's been awhile since I read on NiCad vs NiMH batteries, but I believe the NiCads are supposed to have a longer life expectancy. Technically I'm still using some 10 year old NiCads, but strongly prefer the 15 minute rechargeables. With regard to discharging: I routinely discharge my SINGLE CELL batteries to zero volts - or near that, with a circuit I made using a single cell battery holder and a 10 Watt resistor for each cell. Components readily available at Radio Shack. It typically takes over night or at most a day to completely discharge AA cells that no longer have adequate reserve to power an electronic device. I don't know if it's compulsive foolishness or not to do this, but I had read that it helps to preserve the longevity of NiCads. NiMH's may be different, but I'm discharging them fully until I read something authoritative that says it shouldn't be done. There was a site on the net called Battery University or something along those lines that had a lot of good information. RWL |

I even have one set of my original NiMH batteries that came with it and they are still going strong! The secret is in correctly 'conditioning' the batteries. I condition at every fifth charge and I made labels that I attach to the base of the charger and put a check mark in a box every time I charge a set (keep the batteries in sets if you have more than four!) Once I get to the fifth charge I press the buttons to condition the set and leave it to do it's job. The other nice thing about that charger is that you can also charge AAA NiMH cells with it and charge either two or four cells at a time. I use AA cells in my Olympus C-2040 camera (two sets of four so that I can keep a set charged and ready to go) and AAA cells in the multitude of portable MP3 and CD players the kids have. You will also find that it takes a couple of charge/discharge cycles for the cells to come up to full capacity so don't be surprised if they don't seem to last very long when you first get them. They will get better with use! HTH. -- Larry Green |

OT-camera batteries? Olympus C-3000
I had the same results with AA alkalines in a HP215 camera. It's about
enough to **** a guy off. After the camera refused to take more pictures, even though the alkaline batteries weren't depleted (a load-type battery tester would show that they were still good), I tried using alkaline C cells in a holder, with a cord plugged into the power jack on the camera. That didn't work, (error from camera display) and I think it may have been that the wire size was too small (one of those coily cords for cell phones). HP recommended some high energy alkalines that cost about $8-10 for 4 of 'em. I couldn't see spending that kind of money on disposable batteries. I found an external power supply branded DigiPower from an eBay seller that works flawlessly with the power hungry camera. The power supply isn't the typical wall wart, more like a large AC plug, and has a long cord (maybe 12-15 ft.). It's a switchmode PS, and doesn't have a big transformer, so it's very compact. The output is rated at 2 amps, so the camera doesn't see a slump in voltage, which is what happened with the AA batteries. Common wall warts with wound transformers, rectifiers and a capacitor may not give acceptable performance (even if they're a regulated voltage PS). Of course, that doesn't solve the portability issue. I have a low opinion of nicads (1.2V btw) unless they're made in Japan, from Digi-Key or another source with good inventory turn-over, ensuring high quality and fresh stock. I've been looking at nimh batteries (1.25V, not 1.2V) with chargers at retail places, and see a lot of combo paks at low prices. I'm not optimistic of electronic devices made in China, particularly when there may be a lot of hand soldering involved. The Harbor Freight stuff and other China products I've bought had very low quality soldering joints, loose enough to separate with just a slight tug, barely tacked in place. The nimh batteries are the latest great performer, and I suspect that every small manufacturing facility will be turning out ship loads of inferior products to be bought, then thrown away, by the American market. While I was at a local Dollar store, I noticed about 6 different 4-cell/charger combo paks. I guesstimate that 4 out of 6 are probably total crap.. resulting in damaged cells from over/undercharging, bad assembly work, poor design, bad cells, low quality components. No way to tell which one might actually work well, but then they were only $8-10 each. A good solution for someone that takes a lot of pictures would probably be a power grip (handle with battery compartment built in, that the camera mounts to, and a short lead that plugs into the power jack on the camera), using freshly charged nimh batteries in the camera (and the grip), and having the extra batteries in the power grip available if the camera batteries go low.

So Ive been doing some research on digital camera batts this evening, along with chargers etc It would appear that everyone is pushing Nickle metal hydride rechargables. Which for me..is better..NIMH or NiCads? It may be weeks or longer before I need to take any pictures and am worried about the self discharge of the NiMH batts On the other hand..NiCads appear to be only 800mah at best, based on ebay descriptions On the gripping hand...NiMH appear to have over twice the amp hour rating..1800 is average for AAs, going up to 2500 mah |

I buy the Energizer Lithium E2s. Not cheap, but about 5 year shelf life, and over 400 shots with my Kodak 3.1 Megapixel optical zoom camera, using the LCD viewfinder, and a fair amount of flash. They handilly outlast a 2100mah Nimh. Nicads for a camera STINK because of the self discharge. Every time you want to use the camera you need to recharge the battery. I generally pay less than $4 each for them.(canadian). They are the blue and silver jobbies - model L91. The ones I just pulled out of my camera have a 2019 best before date.

Any input would be appreciated. Also..anyone have one of these cameras AND the proper AC wall wart? I need to know the voltage and polarity. The manual I downloaded didnt have any specs Thanks Gunner "Pax Americana is a philosophy. Hardly an empire.

Are you sure that the alkaline batteries are truly dead? Alkalines don't keep up with the high current draw of some cameras, and experience voltage droop -- let them sit and they often recover to some extent (maybe even to what appears as "full charge"). Which for me..is better..NIMH or NiCads? It may be weeks or longer before I need to take any pictures and am worried about the self discharge of the NiMH batts I think the self discharge between them is fairly similar, longer term. The NiCds will take more abuse before they're destroyed (unregulated charging, overcharging, etc), but the NiMH will have better capacity. NiMH also require a special charger (not the cheapie NiCd chargers). This is a good link: http://ibet.asttbc.org/batterys.htm And some other NiCd/NiMH links I've collected over the years: http://www.zbattery.com/zbattery/memoryeffect.html http://www.buchmann.ca/chap10-page1.asp http://www.houseofbatteries.com/HowTo/NiCd.htm http://www.houseofbatteries.com/HowTo/Secondary.htm http://www.angelfire.com/electronic/hayles/charge1.html http://www.repairfaq.org/ELE/F_NiCd_Battery.html http://www.batteryuniversity.com/print-partone-4.htm And for Lead acid applications (since I noticed this link while looking thru my rechargeable battery tech pages for you Gunner) http://www.uuhome.de/william.darden/ I would recommend you save these pages to your HDD, as several of my old favorite sites have dropped their pages... On the gripping hand...NiMH appear to have over twice the amp hour rating..1800 is average for AAs, going up to 2500 mah And, if you get a decent charger, you can leave the NiMH in the charger until you need them. If you're worried about self-discharge, then load the camera with Alkalines for "ready action", if you really need that, and leave the NiMHs in the charger. I leave the NiMHs in my camera, and periodically (every 2-3 weeks) swap them out, and run them through the charger. I've not had any problems so far. BTW, a warning about wall-warts... Most of them are not regulated, so if you're worried about providing the correct voltage to your camera, snip into the +V line, and install a regulator (also, if you're planning on doing this, then you should get a wall-wart with a voltage rating a couple volts over your required regulated voltage -- most of the regulators require about 2 Volts overhead)... Let me know if you need more info on this. Retief |
