6 FAQs about [Lead-acid battery voltage equalization principle]

What is equalizing charge in a lead acid battery?

Should you use equalization charge for flooded lead acid batteries?

If the specific gravity of the cells varies by 0.03 or more, you should apply equalization charge. Now, specific gravity measurements can be taken for flooded lead acid batteries only. So equalizing charge is ideally suited for such batteries only.

What is the equalizing voltage for a 12 volt battery?

The spec specifies equalizing voltage 14.1 V for 12 V block @ 25 °C (77 °F). I keep the batteries in an outdoor shed, and the temperature where I live tends to hang around 0 °C (32 °F) these days. So, for lead acid chemistry, would the equalizing voltage go up or down with temperature going down?

Why is a lead acid battery a little less?

It’s always a little bit less due to losses and internal resistance. A Lead-Acid battery consists of two primary components: lead dioxide (PbO2) as the positive plate and sponge lead (Pb) as the negative plate. Both od those electrodes are submerged in an electrolyte solution of sulfuric acid (H2SO4).

What are the 3 charging stages of a lead acid battery?

Bulk, Absorption, and Float are the 3 main charging stages of a typical lead acid battery. In addition, there could be one more stage called equalizing charge. Bulk Charging Stage So, the first charging stage is bulk, in which the battery is typically less than 80% charged.

How does an active equalization system affect a pack of batteries?

Figure 2 illustrates the impact of using an active equalization system for a pack of batteries. Indeed, with an active equalization system, a pack of batteries accomplishes at least 450 charging/discharging cycles, where the pack of batteries without active equalization reaches only 140 driving cycles.
