I got this for my Dell Inspiron 1525 and it only charged once to 100%, after that it would charge a bit but would not charge all the way. As of now the battery is sitting at 0% and won't charge. I've had the battery for about a week now.
The battery charger plugs into computer not the battery...???? maybe something is wrong with the charger...take the charger to a computer place and have them check if its putting out ,the charger might not be charging. If you have a voltmeter you can check the charger yourself or maybe the battery they sent you might be bad.
