recharging a cordless drill battery?

Question

i have 3 dead ryobi batterys, they sell plans on ebay to recharge a battery that wont take a charge. dose anyone know how?

Answer 1

There is a possibility that there might be something out there that can instill life back into a Ryobi battery, but it's slim. How come you have 3 dead? are they stone cold dead, if so that could be your charger malfunctioning, because It's unlikely that all three a just dead, if they are wearing out they still will take some charge, even a dead one will give you a small charge. I'll just bet that the charger tip end needs replacing, is all, it's not making a good contact with the battery base, thus no charge. I have a couple of Ryobi's and that was the problem I had with mine not charging.I cut off the tip, spliced on a new one and I was good to go. Is the red lite illuminating when you plug it in to charge? It should.

Plug the battery charger directly into the outlet. Avoid using extension cords to reduce the effects of voltage drop. Cordless drill battery chargers use transformers and solid-state components for charging batteries. Supplying less than adequate voltage to the charger has the potential to cause overheating and damage to the charger and battery.

Remove the battery from the drill and wipe any debris from the exposed terminals before inserting it in the charger. Line up the battery with the charger and slide it in all the way. A red or green power light will come on when the battery is in the charger. Different cordless tool manufacturers build chargers specifically for their batteries. For this reason, most batteries will only fit into chargers provided by the same company.

Charge cordless drill batteries when temperatures are between freezing and 100 degrees Fahrenheit. Keep the charger clean and the vents free of debris. Allow the battery to stay on charge until the charger indicator shows the charge to be complete. Because different tool manufactures use a different sequence of colored indicator lights on their chargers, check the tools operating manual for the meaning of each light. Today's chargers often have a legend stuck to the charger showing what each light means and how to tell when the charge is complete.

Better buy a new one. After a battery dies theres no way use it again.
