Hi, I tried out the suggestions mentioned in your previous mail: - Left the battery out for longer than 30 minutes - Used a Desktop to charge for more than 6 hours.
Unfortunately, the battery is still dead. I am now suspecting the charging circuit or possibly the battery has gone into a highly deep discharge state. I'll probably get hold of a digital multimeter and check the voltages being delivered to the battery. Any other suggestions are always welcome.

I suggest trying again for a longer time, perhaps 30 minutes. I don't know that 30 minutes are required, but I do know that when I do this, I usually forget and don't get back to that project for much longer than 10 minutes. > > I am using a Dell laptop to charge it.

Possible, but I've handled well over a dozen batteries by now and have yet to see one fail this way. Not to say it's impossible. Where are you located?
