DOA. Installed in a T42 running the latest Windows 7 with the latest BIOS.

The power light kept flashing amber. Windows reported that it was plugged in but not charging. As soon as line power was removed, the laptop shut down. Effectively, the battery was not seen at all.

I tried re-seating the battery several times in case it was just an issue with dirty / misaligned contacts. No improvement.

Note that it was mis-sized by about 1/2-1mm, so that the back of the laptop was not flush, as it is with the original IBM battery. Maybe poor fit is the reason it didn't work, but I simply could not make it fit any better.

On the plus side, because this was fulfilled by Amazon, shipping, return and refund were quick and easy as usual. Given the ease of ordering and returning on Amazon, you might try your luck despite my 1-star experience. Some people seem to have gotten a working battery, maybe its a mixed lot. "You never know."

This battery fits perfectly and works great. I have not done an endurance test to see the absolute limit of time, but for the short periods I power up unplugged, it works just fine. The important thing is that my T43 likes it - has no compatibility issues.

The battery seems good and offers much greater life than the worn out old battery that it replaced. That being said the case isn't quite "perfect" and doesn't fit quite flush with the case of the computer. That being said, this battery seems to present great value for the dollar and is a good way to keep your old laptop computer churning for a while longer.

This is my first t-40 battery for this ancient machine I've retro"d. It has charged and drained as scheduled, and considering there is only 4400mah it runs this little machine reasonable long. Maybe it's Debian 8 that’s helping, but the battery works. If it fails, I'll write back!

It fits, but the latch needed a little work with a razor knife to make it latch properly. Looked like extra flashing from the mold. Other than that, it takes a charge and holds a charge. Get similar to OEM run time out of it. A great alternative to the OEM at a fraction of the cost.

Bought 2 of these to replace dead factory ones - figured for the price it wasn't going to be the best but just needed something.

Both would not fit - came close but would not snap and lock. Bulges in the middle but didn't care about looks but probably helped with it not fitting. Tried to even charge them to see if that works as I could shave the case or tape it - that didn't even work.

Good luck but I would go with something else.

The battery came on time and looked like new with full capacity. However, upon examining the voltage requirement for this battery, I found out thatit does not comply with the OEM charger for IBM R51. (It may be good for other IBM R series model, but definitely not for mine) I have let it charged overnight for more than 24 hours and the battery is still not charged at all. Now I just use it until it is fully discharged and dispose it...A total waste.

This battery looked the same as my original R52 model battery, but just slightly longer. it would not go all the way in even with forcing it. It would not snap in place, making any slight jarring makes the battery pop out. I never attempted to charge it and just sent it back.
