How to charge lead-acid batteries correctly?

by：Vglory 2021-03-23

The initial charging of a lead-acid battery is generally carried out in two steps: First, the initial current is used to charge until the electrolyte releases bubbles, and the single cell voltage of the battery rises to 2.3-2.4V. Then continue to charge the current to 1/2 of the initial current until the electrolyte releases violent bubbles, and the voltage should continue to remain stable at 3H. The total charging time is about 45-65H. It should be overflowing when charging for the first time, but overflowing does not mean overcharging. Under normal circumstances, the charging time is about 5-6 hours, so that the battery can be overflowed. The daytime charging time is easier to grasp, and the subsequent charging can slightly increase the time. When using lead-acid batteries, develop the habit of charging on the day of use. Do not wait for the battery to run out and then recharge, so as not to shorten the battery life due to deep discharge. Fully charged batteries should be charged every month if they are not used for a long time. once. Do not charge with the battery upside down.
