Opened laptop battery to replace lithium ion cells (Lenovo X61tablet PC) -- Where do I get replacement battery cells?
Have you ever opened up your laptop battery to replace the lithium ion
cells inside (if so, I could use the help as I'm stuck). Here are the pictures of the operation on a Lenovo X61 tablet PC 8-cell 4500 amp-hour battery kidney-transplant operation. The outside of the IBM Lenovo X61 tablet PC battery pack has the part numbers: - FRU 42T4507 - ASM 42T5209 And the batteries themselves, seem to have numbers on them of: - cylinders BCM 3A6 72653 - rectangles C 3 171353 Any idea where to obtain these lithium ion replacement batteries? |

I think its a waste of time and risky, those are machine welded, you will never get them as compact and fit back in place like machine made packs, soldering and the heat degrades cells, you probably have electronics in those packs which actualy may be bad , not the batteries, did you test the voltage of each cell to see if they realy dont charge , you might buy and solder them up and they will never fit back in the holder. |

Right off I am not familar with your bateries, although my guess(tm) is that you can find them on ebay or google if you search for lithium ion cells. Some come with tabs welded to them so you can solder them togeather eaisly and avoid destroying the battery via heat. If they are the right size and right chemestry they should work. The mAh rating will probably be higher on new batteries than the originals becuase of advancements in battery technology. Just be careful and dont get these things too hot while soldering. They have been known to burst into flames like a flare. I highly suggest you buy the tabbed verison. Mike |

I fix about everything I can but not laptop batteries.

What I do is search the web and buy a replacement battery with a decent warranty. I doubt you can even buy the new cells for what the entire new battery costs. Worst case of do it yourself repair would be a fire some day when it's charging or being used. Here's one on e-bay for 42 bucks says it has a 3 year warranty and the dude is a power seller with a decent track record.

Have you ever taken one of those chinese made aftermarket batteries apart? It is scary to say the least in some of them and amazing that it works. At least if you build it yourself you know if you put good panasonic cells in it that shouldnt spontaneously combust. But if you arent expirenced at soldering and electronics, I cant say I reccomend you try this as a first soldering project.. As stated by "Mr.Fatter" they can catch on fire if not properly taken care of.. The biggest issue is when soldering is not to heat the battery. Get ones with tabs attached to them. |

Mine were a mess and would never fit back into a plastic case, freezing the cell first in your deep freeze will help but I think he will fail for several reasons.- Hide quoted text - - Show quoted text - I just rebuilt a Nicad battery pack for my 20+ year old Milwaukee cordless driver drill. I found the batteries on Ebay for $21, so decided it was worth a try. I was successful and it's working great. But I do agree there are some real issues. In particular, I was very lucky that I got it to fit back into the battery housing. In the factory, the metal tab conductors are spot welded directly to the batteries and go from one to the next. When you DIY, you have to solder them and then when you stack batteries on top of each other the overall height increases. I got lucky because there was a rubber cushion on the bottom which I removed to give me just a little more room. Having been through it once, next time I could plan better to possibly change the wire routing to avoid any solder bump issues. It was also a bit tricky because the batteries had some charge in them, so I had to be careful of what I was doing and not short them out and have a meltdown. In the case of a laptop battery pack I'd carefully weigh the cost of trying and failing vs the cost of a new battery pack. Also, I found places that will rebuild your battery pack for you for the cordless drills. Similar may exist for the notebook battery. However, the pricing for the rebuild was so close to the price of a new battery pack that I would have gone with the new one. I have an older Gateway notebook and after having bought one replacement battery for it, I finally gave up. I realized that 99% of the time, the way I'm using it, I have power available. I may take it on a trip, but I don't use it on the plane, etc. |

Matched - No. Assuming you install them with the correct polarity and the protection module is functioning correctly, the explosion risks are from another category. There is also a connection sequence for attaching the module to the series-connected cells. IIRC it starts at the most positive terminal and progresses to the negative end last. But matching IS important in that the protection module monitors cell voltage DIFFERENCES. This has a two-fold effect. If the diffences exceed a certain threshold value, the pack will be disabled by the module. Below that threshold value, end-of-charge voltage will be determined by the highest cell voltage (which leaves the others less than fully charged) while end-of-discharge is conversely determined by the lowest cell voltage. So as the differential increases the usable capacity reduces in the interests of safety. |

No, that would only apply to packs without a protection module (such as NiXX chemistries). LiXX protection modules will intervene and open-circuit the pack when the lowest cell voltage reaches a predetermined threshold - usually 3v0. |

When I did a similar thing with my Ni Cad driver/drill battery pack I found the batteries on Ebay. Also one would think googling rebuilding Lenovo battery pack, etc might produce results. NiCds are usually standard cells packaged in a proprietary housing. LiIon cells themselves are usually proprietary. It's dangerous replacing them with cells that aren't identical to the originals. Just buy the whole assembly. They're usually available from aftermarket sources for about a third of what Lenovo wants. Sometimes there are issues with the laptop not recognizing the chip in the battery but a reputable source will help. |

Dear Joe I'd like Answers to the same Problem! Executive summary...GIVE IT UP. Details... While getting the cells, be sure to pick up a battery tab welder. Yes, you can buy tabbed cells, but the fit is usually too tight to accommodate a solder joint at the tabs. Anybody recommending you solder directly to the cells probably races motorcycles drunk and has unprotected sex with $2 hookers. Wear face protection. NOT GOGGLES. Wear a full-face helmet with windshield. Exploding cells can knock goggles right off...ask me how I know. You could do this with NiCd cells. Lithium, not so much. The protection chip is designed to thwart your efforts. I've NEVER been able to make lithium pack work correctly. Some dells, will power the computer, but the battery gauge doesn't work and it gets rather warm on charge. I've NEVER been able to get an IBM pack to wake up. There's a program available to reprogram the chip. IF it has a program for your pack. IF you want to build a hardware interface and solder wires onto the pack. They claim to be able to do it. The program is priced for industrial users, way above what's cost effective for a few rebuilds. Quality cells will cost about as much a new aftermarket pack. I've bought a few cells of various types of ebay. They were mostly crap. You have no way of telling ahead of time. I tried to get a quote from a local battery store. They wanted to send the pack out of state to see if the guru could actually do that one. Was gonna cost $20/cell plus whatever the guru added on for the rebuild. Rebuilding a computer battery pack is WAY more complicated than replacing the cells in your dust-buster. Did I mention, give it up? |

Dear Joe I'd like Answers to the same Problem! might want to ask over at candlepowerforums and post pics there. so there's two different types of cells in there? Normally I would just expect to see a bank of 18650s... I'm guessing that that is actually 4500 mAh not Ah?

I am glad you correted him because car battery is around 600 AMP/hour A big car battery is about a tenth of that. CCA is a measure of the current available into the starter at some (low) temperature. It is *NOT* amp-hours. |

Hi. I realize that this is an old thread but I just was looking for the same answer you were and wanted to share. That type of li-ion (rectangular with a hard metal case) is a prismatic cell. http://www.powerstream.com/liprism.htm I hope you found this out some time ago but if not here you go. |
