Does Fast Charging NiMH Batteries Cause Damage or Reduce Their Lifespan?
NiMH batteries require three to four full deep and slow or fast charging cycles before reaching their peak capacity. If you need or prefer using a fast NiMH battery charger, it is important to use a device capable of fast charging NiMH Batteries that has been designed to charge quickly without overcharging or causing excess heat ( ie. less damage and longer Lifespan ) Some cheap or poorly designed fast charging NiMH battery chargers will decrease the battery lifespan by overcharging or generating excess heat. These are caused primarily by: Not detecting the End of Charge; and, Continuing to charge at a high rate. Some NiMH Batteries cannot handle high charge currents; and, When heat builds up, the NiMH Battery Charger fails to take appropriate action. Chargers other than fast charging NiMH battery chargers are also capable of causing damage and reducing the lifespan of your NiMH batteries. Using a medium rate or an overnight charger can also cause damage from over charging and the buil
