Lead acid batteries are the most commonly used battery type in PV systems. The reason is that although lead acid batteies have a low energy density, moderate efficiency and high maintenance requirements, they have a long life and low cost compared to other battery types.
As the most common form of battery used in most rechargeable battery applications (e.g., starting car engines), lead acid batteries, therefore, have a well-established and proven technology base. Aokly not only ranks top in Lithium ion battery producers but is also one of the best lead-acid battery manufactures in China.
The sealed lead acid battery is commonly referred to as VRLA battery - valve regulated lead acid battery, and SLA battery - sealed lead acid battery. They are widely used in energy storage, emergency lighting systems, emergency power, communication systems, electric vehicles, etc.
The common battery is the VRLA battery, with capacities ranging from 2V, 4V, 6V,12V, etc. Battery life, ampere-hours, life cycle and depth of discharge will vary depending on the battery selected and the conditions of use.
