Commissioning
Assure battery operation in the clean environment.
Before operation, battery charge voltage must be adjusted as constant value as per ambient
temperature. Such as, at 25
℃
, charge the battery with 2.25V/cell for 16 to 24 hours, or with
2.35Vpc for 8 to 12 hours;
If the storage condition is serious, adjust charge voltage is necessary.
Maintenance
1. Cleaning Notes:
Battery appearance, terminal area and working environment must be kept clean and dry.
In battery cleaning process, avoid use of electrostatic cleaning tools.
Clean the battery with damp cloth. Do not use of gasoline, alcohol or other organic solvents;
also do not use cloth containing these substances.
2. Inspection and Maintenance
VRLA batteries are not maintenance-free batteries, battery operation process gradually
changes with time. In order to ensure good battery usage, operational management and
control are very important. To understand the operation status of batteries and equipment
and to prevent accidental damage, regular maintenance is required. Periodically check
and record the measurements using the following method for batteries used in UPS system
room and base station (including outdoor station) site.
