Tips: Rechargeable batteries don't last forever — the average battery last 1 to 3 years. If the battery is old/dead, it will not accept a charge, which is not the charger's problem. If you're unsure whether the battery or the charger is failing, you must have a volt meter in order to tell whether or not a charger is working.
