Lead acid batteries are heavy and contain a caustic liquid electrolyte, but are often still the battery of choice because of their high current density. The lead acid battery in your automobile consists of six cells connected in series to give 12 V. Their low cost and high current output makes these excellent candidates for providing power for automobile starter motors.
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
Applications that have these profiles are solar energy storage and energy storage for off-grid power. Two of the most common mistakes that lead to lead-acid battery damage involve charging — or lack thereof. Some owners discharge their batteries too deeply, permanently altering their chemistry and function.
A lack of maintenance or improper maintenance is also one of the biggest causes of damage to lead-acid batteries, generally from the electrolyte solution having too much or too little water. All of the ways lead acid can be damaged are not issues for lithium and why our batteries are far superior for energy storage applications.
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate. As more material sheds, the effective surface area of the plates diminishes, reducing the battery’s capacity to store and discharge energy efficiently.
Internal shorts represent a more serious issue for lead-acid batteries, often leading to rapid self-discharge and severe performance loss. They occur when there is an unintended electrical connection within the battery, typically between the positive and negative plates.

Get PriceA car battery is a lead-acid battery. It consists of a series of lead plates immersed in an acidic solution. When the engine is running, the alternator charges the battery, which provides power to the starter motor and other electrical accessories. When the engine is not running, the battery provides power to these same accessories.
Get PriceThe car battery is considered a wet cell design. Each battery contains six cells filled with lead alloy plates and a sulfuric acid solution, known as the electrolyte. Each cell will produce about two volts of energy, creating the 12-volt battery. The sulfuric acid triggers a chemical reaction between the plates, causing it to produce lead ...
