7.1 Operation
The UPS system contains no user-serviceable parts. If the battery service life (3 - 5
years at 25°C ambient temperature) has been exceeded, the batteries must be
replaced. In this case please contact seller.
7.2 Storage
If the batteries are stored in temperate 20°C~25°C, they should be charged every three
months for 1-2 hours. You should shorten the charging intervals to two months at
locations subject to high temperatures.
