Yes, when a battery is being used for a long time, you need to let it cool down and take it to charged. Although there is many fast charger now, but in order to protect the battery, I recommend you to buy a second battery for replace.

And, if you do not know where to find the right one? Here is some suggestion for your Dewalt DC920KA Battery

Depending on how old or more to the point how many times you have already charged the battery, it may be worn out. All rechargeable batteries do reach a point where they won't charge up anymore. If you have fully discharged the battery and tried to fully charge it up again and it won't take a charge or only lasts a few minutes on a charge it may be time to recycle it and buy a new one.

should be coverd by warrenty

You may want to try a different charger base. Any way you can borrow one so you don't have to purchase first?
If for some reason the charger isn't working well, you may be getting a partial charge and only that.

You may even want to rent a cordless just to try charging your own battery on a different base.
before you buy.

if it is under warranty ,take it back .if it isnot then bite the bullet and buy a new battery ----try TOOLKING

if the battery are less than a yr old should be a warranty
if drill DC920 or DC925 they are on recall for switch. may be co'z the battery to die. have them check at ur nearest service center.
