I have an HP/Compaq Presario CQ50 laptop. This is my 1st computer. It says I need a new battery. The reviews for the HP replacement are abysmal. I "Googled" "battery replacement" and clicked on a site called Technology 8 or something like that. Found a battery for half the price, says the cell is made by Sanyo. Can I trust a non-OEM battery? I rarely use my laptop on battery power, only to walk to Mom's room to show her something. This one has lasted since Dec 2010. Thanks in advance.
