How to Prolong Lithium-based Batteries :  battery

1. Cycle life as a function of depth of discharge
A partial discharge reduces stress and prolongs battery life

2. Estimated recoverable capacity when storing Li-ion for one year at various temperatures
Elevated temperature hastens capacity loss. The capacity cannot be restored. Not all Li-ion systems behave the same.

Simple Guidelines for Storing Batteries

  • Primary batteries store well. Alkaline and primary lithium batteries can be stored for 10 years with moderate loss capacity.
  • Remove battery from the equipment and store in a dry and cool place.
  • Avoid freezing. Batteries freeze more easily if in discharged state.
  • Lithium-ion must be stored in a charged state, ideally 40 percent. This assures that the battery will not drop below 2.50V/cell with self-discharge and fall asleep.
  • Discard Li-ion if the voltage has stayed below 2.00/V/cell for more than a week.
