This battery worked well for the first year or so. Recently, after 16 months of use, the battery now does not support computer operations for more than a few minutes before failing. It does not give a low-battery warning, but just fails and the computer crashes. The LEDs on the battery still show a full charge, but the computer will not turn on until plugged in. After it has charged back up a little, it will work properly, but again for just a few minutes.I won't recommend this battery or buy it again.
