CR 2032 batterry vs. 2025
Any reason why I can't use a CR 2032 batterry in an IBM Thinkpad about
12 years old, instead of the 2025 it came with? They're both 3 volts, both lithium, neither rechargeable, both the same size. I'm sure there's some difference but I would think either would work fine ?? Thanks. |

For 9 or 10 dollars., I coudl buy a 2025 already soldered to a wire with a connector, and heatshrunk,, but I hasen't time to wait for it to be delivered. |

Since the CR2025 is thinner, you have to fiddle with it, to get the clip to grip it. And if the computer is shaken or bumped, it could come loose and make a poor connection. I don't know if it could completely escape the socket or not. I got it to hold well enough for my purposes (desktop - located stationary on a table). Batteries have a voltage rating and a milliamp-hour rating. The voltage on the CR2032 and CR2025 is the same. The milliamp-hour rating of the CR2025 is lower, so it lasts fewer years when called on. Will it last for a week or two, while you're getting the proper battery ? Sure. The CR2032 is around 225 mAh. The CR2025 is 163 mAh. So the CR2025 lasts about 72% of the life of the CR2032, about 2 years worth if the computer is unplugged. Paul |

So the CR2025 lasts about 72% of the life of the CR2032, about 2 years worth if the computer is unplugged. Paul Two years is a substantial difference. I used to know how old this laptop was, but maybe 12 years now. I bought it maybe 4 years ago on Ebay and it worked just fine. It may have has had the original battery all this time becuase I didnt' replace it This all relates to my prior thread about attaching leads straight to the battery. There is actually no battery holder in the IBM Thinkpad 600E, just a little connector a short pair of wires and leads that are spotwelded straight to the battery. Then it's all heatshrunk and stuffed in a little spare space. Somehwhere you asked me to use my imagination, but I already had. There was just no spare space in the memory compartment, where the connectiion is, and no way to get to the other compartments, except maybe by taking it apart far more than I want to do. So before I buy the 9 dollar battery, or even the 4 dollar battery hoder that holds from the side, that is on the page John McGraw found me., I want to know if the computer works with the new harddrive, so I decided to make the wires t0 inches long and route them where the CD drive slides into the bay, through the crack and outside the computer. Then I put some heatshink on. And the computer does start now, though it doesn't yet boot for some reason. I've been using the partition software, 7 different programs, on Hirend's boot Cd to try to figure it out. I'm tired tonight. I'll work on it tomorrow. But the battery holder was designed for a 2032, and I bought it at RShack for $1.19. Yesterday I ripped one from an old mobo, destroyed the whole computer to get it , but it was even thicker than this one. I hoped this one might be thin enough. but it wasn't, I thought I had to get this done by Wednesday or Thursday to take it with me to meet my brother's family in the Smokey mountains**, but last night I arranged to boroow a much more recent ACER notebook. Maybe this one will be ready after all. **It's not that I need my email so much, or even newsgroups, but I think I will need tourist information for my drive down and back, a day and half each way. While I'm there, my older brother is in charge. |

If you stack them, you will add the amps - why not put in 2 on top of each other, both the same way round. |

Putting them side by side would add the maximum amperage, and share the battery depletion between them, at the same voltage. So they would last twice as long. They don't make battery holders like that either. but one could t ape two of the singles together, and dangle it outside the laptop like I did mine. I did this with my uninterputible power supply. It came with ribs inside definiing the space for the battery. I broke out the ribs and put in a bitgger battery, same voltage, more maH in parallel. It will twice as long to fully charge, but there is plenty of time to charge. When I need it to power the computer, it will be charged and last twice as long. |

CR 2032 batterry vs. 2025
Yeah, you can use it. The 32, the 25, and the 16 are pretty much interchangable except as noted above. I cut the battery terminals close to the battery and shoved them into the space between the replacement battery and a piece of shrinktube then shrunk the tubing down. Made good enough contact to keep things lit up for the last 3 or 4 years. The next time I may add a contact pad to the end of the wire. I'm generally leary of the cheap batteries. Don't mind using them for car door locks or scales but don't trust them in most computers where they are buried in the innards. |
