Page 21: Storage
Floating charge Floating operation is the best operation condition for battery. In floating operation, the battery keep fully charged state, under this condition, battery could reach the longest service life. For floating operation, the charge voltage should be suitable adjusted according to ambient temperature as shown in Table 3-2. - Page 22 Quarterly Maintenance Repeat every item of monthly inspection. Measure and record the floating voltage of each on-line battery. After temperature emendation, if more two batteries with a voltage of lower than 2.18V, the battery system needs equalizing charge. If the problem is not solved, go on annually maintenance even three yearly maintenance items.
