So, I got 3 years out of a laptop battery, but it finally failed. Not bad.

[HopeHoops]

The laptop is a 17" HP (dv9000) and a total power hog. I love the thing and use it constantly, on and off the cord. I had noticed the battery life dwindling from its original whopping 2 1/2 hours down to under an hour, but over the last couple of weeks it couldn't get the battery over a 17% charge even when it was plugged in 24x7. So, I bit the bullet and ordered a new one. FORTUNATELY, they were on sale at $35 off the regular price! Free shipping, too (which is always nice). It showed up with a 58% charge less than an hour ago and it is already at 89%. I'm happier now.

I think the longest I've gotten from a laptop battery was about 5 years. How about everyone else?
