Basically charging rates for UPS batteries depend on type of batteries cell such as Lead-acid (Pb) or Nickel Cadmium (NiCd).This two types of batteries cell have a different method to charging up. For Lead-acid (Pb) cells is used a ‘constant voltage’ method.It mean where the current varies as the state of charge changes.Different method for [...]
When indicator for batteries level shown a it need to recharge,We must charge the batteries to ensure it in full capacity and can operate during power failure.But for UPS batteries charger it typically build in the UPS system.
