just ordered new battery for my hp laptop. 10.8v 8800mah 2 year warranty. most other sites seem to only offer 1 year. Of course, the warranty may not be worth the paper it's written on. 89 bones. free shipping.

If it isn't a mfg battery made for your system by the computer company, you might check to see if the company that made it has had any recalls.

some outside mfg batteries have had serious problems in the past, including frying 'puter systems and catching or causing fire by heating up too much. I spent the extra 50 bones on a Dell battery, because the cheaper ones just didn't seem worth the risk for the money.

There is no warranty on the system they fry, only on the battery.
