Dorset battery 12V120AH quotes Applications ● electrical equipment ● Communication equipment ● UPS / EPS power handling, storage ● battery heavy and brittle shell, handling should be gently, non-tumbling and wrestling storage battery, taking care not to make the terminal by force. ● Battery should be stored or installed in a dry and ventilated place, away from direct sunlight, away from heat and place is easy to produce sparks. ● Before storing the battery should be full charged state, does not allow discharge after storage. ● Battery should be under the environment 0 ℃ ~ 30 ℃ storage, storage batteries should be carried out once every three months to add power, the longest storage time should not exceed one year, otherwise the battery capacity and life will be reduced. 4. Maintenance Maintenance Monthly maintenance cycle maintenance item 1. Thoroughly clean and maintain housing, clean the terminals and a vent flow; 2. Check housing for deformation, whether terminal corrosion discoloration, whether leakage; 3. Measurement and record the ambient temperature, the temperature of the battery case and the pole temperature; 4. Measure and record the total voltage of the battery pack, charging voltage drift or changes in circumstances should adjust charging parameters. Monthly maintenance 1. Repeat quarterly maintenance items; 2. Measure and record the single battery float voltage, float current and other parameters, and timely adjustments; 3. Check the connecting member is loose, if loose should be tightened screws; 4 For balanced charging the battery, the charging time 24H. Annual maintenance 1. Repeat quarterly maintenance items; 2. Check the safety valve is loose, and tighten, but do not remove the safety valve; 3. Battery Pack to conduct a verification of the actual load discharge test, release the rated capacity of 30 % ~ 40%. Three years maintenance 1. Repeat the annual maintenance; 2. Make 10Hr capacity test, release 80% of rated capacity.
