Gateway Laptop Battery Dies In 3 Months?

I have had a Gateway laptop for just a little over a year. About every 3 months the bGateway Laptop Battery fault light comes on. Gateway gave me two new Laptop Battery and even "fixed" the computer after I sent it back and installed a third battery. When asked they said their fix was just a new battery. Warranty is now out and same problem continues. Gateway says it is now my problem as it is out of warranty.




The battery indicator will go to "0" charge but will run for 1-1/2 hrs (battery not really dead).




Any help will be appreciated.

Shall I have to buy a new one? How about Lenovo Laptop Battery?
