2. The battery must be kept in full charge state. Due to in transit or retention of the internal cause of the discharge will lose part of the capaci
1, UPS floating charge, please use the charging voltage 2.275v/Single-cell (20 ℃ setting value), the fixed voltage charge or 0.002CA below the current for fixed current charging.
Voltage stability---a mains voltage is susceptible to the power transmission line quality, from the transformer substation more near the user voltage is higher than 130~120v
