Make sure you check if your replacement battery is the 12.25v or the 7.4v. This laptop could have came with either.

Actually you could to upgrade your battery from 43 WHR to 52.5 WHR but this requiring little bit research…

So is there a battery shaped similarly that will increase the battery life? My laptop will only last about 2 hours.

Hi, is your battery is 52.5 Whr? Is it orginal?

If the answer to both is yes, I would recommend to replace the battery because it might be dying (wearing).

but before you change it check with the lenovo support what battery can you buy.

(support lenovo-register-detect device-parts-recharble batteries)

if that doesnt help you can always ask lenovo support specialist
