I have a Royobi 12 volt drill which came with 2 batteries.
It is now approximately 2 years old and neither battery will hold a charge
for longer than a day.
I assume that this is due to a memory problem with the nicad batteries.
I am not sure why this has happened as my previous battery drill is probably
9 years old but is still capable of retaining a charge.
Is there anything on the market that will revive the batteries?
