The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density spite this, they are able to supply high surge currents.These features, along with their low cost, make them …
Charging voltages range between 2.15V per cell (12.9V for a "12V" 6 cell battery) and 2.35V per cell (14.1V for a "12V" 6 cell battery). These voltages can be applied to a fully charged battery without overcharging or damage, since they are below the "gassing" voltage, and cannot break down the electrolyte.
Lead-acid batteries come in different types, including flooded (wet), absorbed glass mat (AGM), and gel batteries. Each type has specific charging requirements regarding …
