Is there a way to fix/charge a dead battery?

[Nina]

I have two compaq presario batteries, one shows at 6%, the other, as
uknown, that won't charge. Is there a way to fix these batteries so
they will charge again, before I go spend another 200 bucks?

Thanks

probably not... You might try taking it down to your local battery shop and
try having it reconditioned or they should be able to rebuild it cheaper
than a new battery, but its still pretty expensive.

reconditioning is usually ~ $15
a rebuild they replace all of the cells and is usually a little cheaper than
buying a new battery, and is just as good.

Thanks, I found a third battery that is at 70% and the laptop still
wouldn't charge it. So, I think the problem is with the laptop, not
the batteries. I just get a blinking orange light (instead of the
solid orange when it's charging) and the batteries never charge at
all, even after hours of the lappy being plugged in.

So, I am back to the question of finding an external charger that's
not too expensive. Hope you have some ideas on that. thanks

if its lithium-ion type which is controled with micro-processers
because they are dangerous and need very rigid charging cycle. They
are not to be fully discharged or sometimes the charger will never
kick in. I had a dead sony nicad camcorder battery (not lithium which
I would not mess with this way) that would not charge. so I manually
zapped it a few seconds with a car battery charger to get some volts
to readout. Then back to the sony charger and it charged up fine and
the camera liked it to!
