Query: Poor long term life

This batter fits well in a Dell 6000 and I have had no problems with it when I first bought it. The batter had about 2.5 hour run time at first. It worked well for a few months. But now about 6 months later it has a 5 minute life which was very dissapointing since the Dell OEM battery lasted almost 2.5 years. The computer is used allot with at least 1 to 2 charge cycles a day. For about $60 this Lenmar battery you might get 6 - 12 months of use. For a Dell OEM you will see around 2 to 3 years of use. For the money buy OEM unless you need a cheap short term solution.
