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 — this is not the charger's problem.

If you're unsure whether the battery or the charger is faulty, you must have a volt meter in order to tell whether or not a charger is working.
