The Batteries are a vital part of your home UPS inverter system and constitute a large portion of your out lay.
The life span of your battery or battery bank will largely depend on the quality, type of the battery and how well you look after the batteries. Incorrect charging, lack of maintenance or deep discharging are battery killers.
Make sure the inverter you chose has a proper charge controller and low discharge battery protection.
