Tips: Rechargeable batteries don't last forever — the average battery lasts 1 to 3 years. If a battery is old or dead it may not accept a charge; this is not a charger defect. If you are unsure whether the battery or the charger is at fault, you must use a volt meter to determine if the charger is providing the correct output.
