Battery lifetime
The battery life time is aected by the battery temperature. The battery temperature
changes depending on the intake temperature and height of the storage system, the
conguration, operation of the controller boards and drives, charge-discharge count and
others. The battery lifetime will be three to ve years.

down procedure. If not, the battery might reach its lifespan earlier than
expected and become unusable within three years. When replacing the
battery, follow the given procedure for disposing a used battery.
