How To Charge A Lead Acid Battery
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off. During charge, the lead sulfate of the positive plate becomes lead ...
What is Valve Regulated Lead Acid (VRLA) Battery

Freshening Charge – Lead-acid batteries will self-discharge from the day they are manufactured until they are put into service. As it is often several months before the battery is installed, it is important that a "freshening" charge be given before the battery exceeds its storage shelf life. For lead-antimony or selenium, this is usually 3 months, and for lead-calcium, 6 months. Some ...
