"Mike" wrote: I have 2 Milwaukee 12V Li battery devices. One is almost 2 years old and the other about 6 months old. They get used a lot and the batteries hardly get warm from use or recharge. However, being a belt and suspender type guy I use a timer as Leon suggested. Not that I'm particularly worried that they will overheat. I just have an aversion to leaving anything on that doesn't need to be on. ----------------------------------------------------- SFWIW, about 96-97 time line I bought an 18 VDC DeWalt drill and panel saw kit. After about a year, DeWalt issued a recall of the charger due to over heating problems. Got a new changer from DeWalt; however, never had any problems with the original one. Lew |

That is actually where most of the problems are, especially with low end chargers. The better chargers will monitor each cell rather than the pack and if one cell gets higher than the other it will deplete it while bringing the others up. If they are too far out it shuts down. How do you monitor an idividual cell when they are connected in series? Generally they are not just connected in series. Nicads and nimh were, but not lion or lipo. The better batteries have prongs for the drill, or whatever and another set for monitoring the cells. Charging can be done on the normal prongs, but monitoring is done on the second set. They are not monitoring for heat like nicad and nimh, they are monitoring for voltage. They need to be close, and they can't exceed the recommended cells voltage. Same with depletion of batteries, they can't be drawn down to low or they may not charge again, or worse. So the manufacturers have handled that. You'll see all the lion/lipo units stop when voltage drops. So if you are drawing a lot of amps it will cut out. let it cool and the battery bounces back a bit and you can continue... but it's a matter of time b4 it stops running and needs charging. Even the cheapies have something, probably not as good. Take a look at your pack, you will see another set of connectors. I love the Lithium technology the drills are always ready. No quick discharge like the nicad/nimhs had. -- Jeff |

No quick discharge like the nicad/nimhs had. Very good explanation of things I was not aware of - thank you Jeff. I was well aware of the drop off characteristics of LiON, but did not know the underlying logic. I too love LiON, and have had no problems at all with it - either in my laptops or in my drills. -- -Mike- |

Most UPS' (at least mine does) can be configured to power down if it starts getting low on battery power. This is a function of the UPS and not some program like Powerchute which lives on a computer. |

My UPS and my BIL's is designed to work with a computer. It communicates, it's state of charge and or how long the power had been out, with the computer via a USB cable. When the UPS reaches a preprogrammed condition it signals software on the computer to shut down computer before all power is lost. IIRC there is a warning on the computer screen and an audible alarm on the UPS when power is lost. This gives you enough warning of the event and time to save your work should you actually be working on the computer when this all happens. A DVR cannot communicate with a UPS. You mention that your UPS can be configured to power down if it starts getting low on battery power. Is yours not intended to be used with a computer and or does your computer simply lose power from the UPS vs. shutting down before the UPS shuts down? |

On one, the USB interface quit a couple of years ago, so the computer can't talk to it. On a power outage, it still beeps and after a few minutes, it shuts down the UPS protected outlets. It's still OK for short outages. The other two APC units operate the same way except they notify the computers they are attached to and the computers shut down before the UPS outlets are de-activated. -- "Socialism is a philosophy of failure,the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery" -Winston Churchill |

It's intended to work with a computer and will notify you if there's a problem so you can close and save your work. But, if you're not there and there's problem, it will run until the battery gets low and then it runs the Powerchute program on the computer which saves and shuts the computer down. After that if the power gets so low that it's close to a brown out state, it shuts all power off. This is preferable to actually going into the brown out state which can cause serious damage to hardware. So whatever device you have plugged into the UPS, computer, DVD or otherwise, would be shut down. I was under the impression that all/most UPS' could/should be able to do that. |

Mike was referring to the brown out comment, not the fact that non computer devices don't get a shut down signal. My UPS by APC will not "brown out" as the battery runs down, it will shut down instantly with no transient spikes or other damaging activity when it can no longer supply full power to the UPS outlets. So I agree with Mike - a ups that doesn't shutdown instantly when unable to supply full power instead of browning out is nothing I would want powering any device. -- "Socialism is a philosophy of failure,the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery" -Winston Churchill |

All but the most low-end uninterruptable power supplies have a notification means. Anything from relay contacts to a USB port, depending on generation and capability. If the DVR has both a USB host port and UPS software on-board, then it should be able to respond to the UPS low-time notification and initiate an orderly power down procedure. I've read that some Tivo's will support a standard USB HID UPS device, but have no personal experience with that. In any case, a well-designed UPS won't provide a low line voltage to any protected device(s). Unfortunately, there are a glut of cheap, poorly crafted UPS devices available on the market. |

Another case of people not knowing or caring enough to really understand, and simply buying blind eye, wishful confidence. I think you may be FOS. Ease up, Leon. Mike was referring to the brown out comment, not the fact that non computer devices don't get a shut down signal. I missed that part in his comment. I was talking about a UPS shutting down a Satelite/DVR, I thought he was too. My UPS by APC will not "brown out" as the battery runs down, it will shut down instantly with no transient spikes or other damaging activity when it can no longer supply full power to the UPS outlets. So I agree with Mike - a ups that doesn't shutdown instantly when unable to supply full power instead of browning out is nothing I would want powering any device. Given the choice neither would I. Until this conversation I was unaware that such a feature existed. |

My BIL had his satellite system on a UPS to take care of the blips then one day when they were away from the house for a few hours because the power had gone out for an extended period of time the UPS went dead and the satellite tuner/DVR permanently freaked out because of the low voltage coming from the UPS as it was running out of back up power.

Can you name a UPS that will actually do what you said, signal to shut down the satellite receiver/DVR? I don't know of any satellite DVR's that actually communicate with a UPS to power down. All but the most low-end uninterruptable power supplies have a notification means. Anything from relay contacts to a USB port, depending on generation and capability. If the DVR has both a USB host port and UPS software on-board, then it should be able to respond to the UPS low-time notification and initiate an orderly power down procedure. I've read that some Tivo's will support a standard USB HID UPS device, but have no personal experience with that. Understood this is not rocket science, but please tell me which satelite/dvr will have all the features that you mentioned above. Lots of if's you mention. |

I don't know of any satellite DVR's that actually communicate with a UPS to power down. No - I can't. I don't know that DVR's can receive a signal from a UPS. I was (maybe mistakenly) speaking of how a UPS typically associates with a computer. Most provide a signalling for low battery to allow for the computer to shutdown. Exactly, however the major satellite providers don't offer this feature but if they could that would mean that even a crappy UPS would work just fine even though it might not offer protection from it's won from brown out. Another case of people not knowing or caring enough to really understand, and simply buying blind eye, wishful confidence. I think you may be FOS. What? Me? First Offering Sarcasm. ;~) |

So I agree with Mike - a ups that doesn't shutdown instantly when unable to supply full power instead of browning out is nothing I would want powering any device. BTW, an easy way to determine if a UPS shuts down instantly or "browns out" when there is a power outage is to plug in an incandescent light into one of the UPS outlets and then uplug the UPS. After the battery is unable to supply full power, the light should turn off instantly, not dim over minutes or seconds. I would be looking for an easier way at the store before I bought one. APC - no problems. http://www.apc.com/site/products/ind...m/?segmentID=1 I took a look at the APC site, and I have long been aware that APC is a better brand. That said I looked at what appeared to be a low end and a high end " Back-UPS" and looked at the features and benefits section an did not see any thing that specifically pointed out the feature of shutting off out put before voltage dropped to a specific point. I'm not doubting what you are saying about this feature but would certainly like to know what to look for specifically when shopping for a new one. |

That being said, I'd query them and confirm that it will power off instead of going into a brownout condition when the battery is exhausted. http://www.tripplite.com/en/products...xtModelID=3193 |

There was a bad batch of 18V LiON batteries some time ago. Lots of complaints on Amazon about it. Mine are about 3 years old and getting weak, but that's about the lifetime of LiON batteries anyway. My Makitas are NiCd. At my PPoE we had some "new" batteries that were three years old (stock for a widget that was *way* late to market). We grabbed a bunch of them and did a life test. They were still better than 90% capacity. It's not time that kills LiIons (so much), rather charge cycles. Unlike NiCds, they really do have a long shelf life. |

Lamps? No, flipping the switch takes care of that just like the timer on the charger does. Everything in the entertainment center is connected to a power strip. Chargers also present a small power drain even when no batteries are present. My two Milwaukee chargers (NiMH and Li) draw about 10 watts when unloaded. Put them on a timer for 1 hour a day and the trickle charge will keep the batteries up if needed and you can save a few watts (over the losses in powering the timer) and maybe help pay for a new battery after several years. Of course it makes no financial sense to buy a new timer, but if you are like me and have several just sitting in a 'junk' box on a shelf.... -Bruce |

Is yours not intended to be used with a computer and or does your computer simply lose power from the UPS vs. shutting down before the UPS shuts down? It's intended to work with a computer and will notify you if there's a problem so you can close and save your work. But, if you're not there and there's problem, it will run until the battery gets low and then it runs the Powerchute program on the computer which saves and shuts the computer down. After that if the power gets so low that it's close to a brown out state, it shuts all power off. This is preferable to actually going into the brown out state which can cause serious damage to hardware. Gotcha! Obliviously the one my BIL used would not shut power to the device when it got low. So whatever device you have plugged into the UPS, computer, DVD or otherwise, would be shut down. I was under the impression that all/most UPS' could/should be able to do that. Apparently not the older less expensive ones from Cyber Power. 'better' UPSs will only let the battery discharge to about 80% before shutting down, This is to prevent deep cycling the batteries which helps extend their life. I have about a half dozen around the house protecting various things, Any UPS should have batteries that last years if all you get are short power 'blips'. Around here, if it isn't just a blip, it usually will last for about an hour (I guess that means a crew had to be dispatched). I see a definite correlation with battery replacements being more frequent on my cheap vs. 'good' UPSs. -Bruce |
