IBM / Lenovo Thinkpad T61 Battery and Lenovo R61 Battery

My Lenovo R61 battery stopped to serve. I bought this battery to replace my Lenovo R61. It was perfectly compatible with my R61. After I charged this battery for 12 hours I put it into my computer. I do a test in my R61 to ensure if it can continue to run 3 hours without plugging on AC adapter. And the consequence is gratifying.
It is a good replacement for Lenovo R61 battery.

My laptop computer isn't Lenovo Tin Yat F41A, mine is Lenovo T61, but my battery also exist the design flaws. I have bought my T61 over 2 years, it no longer belongs to the range of products can be returned. So I bought my replacement battery from Brilliantstore.com. It works well as the description for two weeks. It seems a 6 cells Lenovo battery. And it can approximately last 3 hours without plugging on AC adapter. I think it is a good replacement for Lenovo T61.

My original Lenovo Thinkpad T61 battery stopped supply when there is 60% of capacity. I seems the state of my battery is good. But I can't find the reasons. I ask some experts in repair computer, they can't tell me the reason. They suggested me to buy a battery. I bought my T61 battery from this site. Finally, it prove that my original Lenovo T61 battery has broken. Now the battery work well and the battery life has returned to 3 hours. By the way, the customer service is really good.

I have a Lenovo T61 FRU P/N 42T5262 and ASM P/N 42T5263. There is also the bar code number: 11S42T5263Z1ZDEJ77TM4E. This battery works very well and gives me enough power to do my work when I'm travelling, and especially on a plane. Will come back to Brilliant Store! Thanks!
