New lead-acid batteries often fail to reach the capacity after the first charge, and should be discharged and cycled. The initial charging of the lead-acid battery is carried out in two stages: first, it is charged with the initial charging current until the electrolyte releases bubbles, and the single cell voltage rises to 2.3~2.4V. Then reduce the current to 1/2 the initial charging current ...
