Cheap chargers kill batteries. Your best option is to either replace it
(which is certainly worth it if they're quality cells in there) or at
very least to run it through a timeswitch and never run it for more
than the recommended 5 hours. Personally I have an old half-hour
"boost" timer that I use for this and charge the battery in a number of
short blasts. This gives it a chance to cool down between bursts.

But those cheap chargers are just crude battery killers. Avoid them if
you possibly can.

I've modified a few to constant current charge at 1/10th battery capacity
- ie approx a 14 hour charge. Overnight is really no more of a problem
than 4 or five hours, and guarantees the longest cell life. It costs less
than a quid for the components.
