I think that your batteries may have expired due to old age and are refusing to hold a charge.
Ni cad batteries have a shelf life and once that time limit has expired, you need to replace the batteries with new ones which will begin counting down to their expire date and also go dead.
once ni cad batteries have expired and past their time limit
nothing can be done to revive them ,they are forevermore dead and must be replaced.
that is the reason why i buy 120 volt ac drills instead of battery powered drills which are always dead by the time i need to use them and wont hold a charge when i try to recharge them.
my cordless radio phone batteries go dead after 1 hour on the phone, when they were newer,i could talk for 4 hours and still have 1/4 charge left. soon they will only last 30 minutes and need a 12 hour recharge to come back to 4 bars.
so i expect to have to pay 4 new batteries by christmas.
One other option may be that your charger is not working properly and developing the required voltage.
that also happens but not as often as dead batteries that wont hold a charge.
if you have a radio shack nearby, even if its a 20 mile drive
they can test your batteries and also test your battery charger. just ask for a salesman that has a battery tester and a vom [volt,ohm,milli amp meter] also called a multi meter. The vom will test your charger and came also test your batteries, but most salesmen dont know enough about the vom to use it as a battery tester .
PS a battery tester is just a vom scaled down for battery testing only, made easy to use for dummies.
