Original Dorset battery BT-HSE38-12 a penalty 1, the battery connection ● different capacities, different performance, different battery manufacturers can not be connected together. ● The actual capacity of the battery or the same battery used in tandem before. ● The actual voltage of the battery or the same battery pack only in parallel. ● battery connections and leads, please use the appropriate wire. ● Be sure to turn off the power when connecting and disconnecting, electric shock or explosion hazard. ● positive and negative can not be reversed or shorted, otherwise it would severely damage the battery, or even an explosion. ● connecting parts should lock to prevent the sparks; if the contact surface is oxidized, available soda water. ● New batteries should be installed before use floating charge for 72 hours so that the internal battery power balance before testing or use. 2, battery charge and discharge ● charging parameter settings used when the float float voltage series models largest single-cell float current temperature compensation coefficient AGM Series 2V series 2.26 ~ 2.28V / cell 0.2C -3mV / ℃ 2.27 ~ 2.30V / cell 0.25C -3mV / ℃ ● recycled charging parameters when setting the maximum charge voltage series models are single-cell charging current temperature compensation coefficient AGM Series 2V series 2.30 ~ 2.35V / cell 0.2C -5mV / ℃ 2.35 ~ 2.40V / cell 0.25C -5mV / ℃ ● discharge current and discharge voltage discharge time (H) 240 120 20 10 Discharge current (A) 0.0042C 0.0083C 0.05C 0.1C discharge termination voltage of 1.97V / cell 1.92V / cell 1.87V / cell 1.82V / cell Note: "C" indicates the rated capacity of 3, 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 vents unblocked; 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 adjustment; 3. Check the connection part 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 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 10Hr capacity test, release 80% of rated capacity.
