About T500 battery issue

I bought a T500 in Jan, 2009. So far my battery only has 53 cycles. But it only could last at most 20min. Sometimes, the gauge shows 60% full, but the next minute it shows less than 1% full and shut down automatically. Although I bought a 3-year warranty for my T500, the representative said the warranty for battery is only one year... And I found I need to spend more than $150 for a new battery...

 

The manufacturer is Sony and FRU number is  42T4623. It is a Li-Ion battery and the gauge still says this battery is in good condition. What's the problem with battery? Do I have to buy a new one?

 

Thanks for any advice.

 

Hao

Re: About T500 battery issue

Thanks, but do I have to buy a new battery back, i.e. 6 cell or 9 cell?

Re: About T500 battery issue

6 cell or 9 cell should all be fine. If you are getting a new battery, you maybe interested in reading this post.

Boston Battery mentioned in the post has 3 years warranty and is only around 70 USD.

Re: About T500 battery issue

do you think this link is good for T500 15.4"?

http://www.laptopcharge.com/category/notebook+battery/ibm/thinkpad+t500/lib200-gs.aspx#pt

 

From power manager, I got my battery FRU# is 42T4623 but from Lenovo website warranty page, I got my battery FRU# is 42T4777, MFG# is 92P1142. It's very weird.

 

From the above link, I found it's compatible with 92P1142, but did not find 42T4623 or 42T4777 in the compatibility list as below:
