  • Page 11 Never attempt to charge or discharge the following types of batteries. A battery pack which consists of different types of cells (including different manufacturers). Non-rechargeable batteries (Explosion hazard). Batteries that require a different charge technique from NiCd, NiMh, Li-ion, Li-Fe, Li-HV, LiPo or Gel cell (Pb, Lead acid).
  • Page 12 Charging. During the charge process,a specific quantity of electrical energy is fed into the battery. The charge quantity is calculated by multiplying the charge current by the charge time. The maximum permissible charge current varies depending on the battery type or its performance and can be found in the information from the battery manufacturer.
  • Page 13 Discharging. The main purpose of discharging is to check the capacity of a battery or to reduce the battery’s voltage to a defined level. The same attention should be paid to the discharging process as charging. The final discharge voltage should be set up correctly to avoid deep-discharging. Lithium batteries cannot be discharged to lower than the minimum voltage, or it will cause a rapid loss of capacity or a total failure.
