Why should we activate the battery?

After long-term use, the battery capacity will gradually decrease. For example, the battery of our mobile phone can be used for a day when we just bought it, but it can only be used for half a day after a year. However, since the substation battery pack has been in a floating charge state for a long time, charging without discharging will cause the anode plate of the battery to be passivated, increase the internal resistance, and reduce the capacity. To avoid emergency power failure, we must perform regular maintenance on the battery. In view of the different actual conditions of backward batteries, carry out capacity tests on backward batteries, low-voltage constant current charging, or set multiple cycles to charge and discharge the smallest capacity battery multiple times to activate the active materials that have failed the battery plates and activate the battery. , improve the capacity of backward batteries.

Battery activation method

Most power stations use a battery activator to maintain battery packs. This instrument can perform a cyclic charge and discharge process on a single or group of batteries and activate the internal chemical components of the battery. First, connect the positive and negative poles of the battery and the activator with wires. Do not reverse the positive and negative poles to avoid burning out the instrument.

Set the test parameters of the activator battery voltage, battery capacity, charging voltage, discharge voltage, and number of cycles according to the battery nameplate information.
