Recommended charging rates

1. Two-stage charge mode.
If it is possible to carry out constant charging from the dedicated converter channel (operation of batteries (batteries) as an emergency power source), a charge with a two-stage mode is more preferable.
 1st stage - charge by current 0.1 It A until the charging voltage of the batteries is reached depending on the ambient temperature:
- at a temperature of plus 40 ° C - 1.40 V per battery;
- at a temperature of plus 30 ºС - 1,43 V per battery;
- at a temperature of plus 20 ° C - 1.46 V per battery;
- at a temperature of plus 10 º C - 1.51 V per battery;
- at a temperature of 0 ° C and below - 1.58 V per battery.
Deviations of the set charging voltage from the set value should not exceed 2%.
The first stage of charge should last for 24 hours.
Then the charger should go to the 2nd stage - a constant charge with a current of no more than 0.005 It A.
The inclusion of the first stage of charge should occur after each disconnection of the centralized power supply or when the voltage of the batteries decreases under a load less than 1.1 V.
When the voltage drops below 1.0 V, the batteries must be forcibly disconnected from all loads and connected only after charging.
2. Charge at constant voltage.
If it is not possible to organize a two-stage charging mode, in order to ensure the installed battery life without refilling of distilled water (when operating in buffer mode), the electrical equipment must provide the following algorithm for changing the charging voltage, depending on the ambient temperature per battery:
- 1.40 V at a temperature of plus 40 ° C;
- 1.43 V at a temperature of plus 30 ° C;
- 1.46 V at a temperature of plus 20 ° C;
- 1.51 V at a temperature of plus 10 ° C;
- 1.58 V at a temperature of 0 ° C or lower.
At the same time, the maximum charging current of the batteries should be limited to the level of 0.1 It A. Accuracy of maintaining the charging voltage is ± 1%.
