Batteries like this can be tricky. You don't know if you have a good one until after several months of use. So far , so good on this one. It charged up fine and seems to be keeping a charge.
My Dell battery seemed to crater early in the first year or two.... made it a laptop always needing a chord unless you could do all you needed in 20 min before it ran out of juice. Very dissapointed. To this battery, I think, Very satisfied. 2months so far..spent a little extra for this brand than the cheapest..now glad..might buy another.
