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.

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

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?
