SLA Lead Acid Batteries

SLA Lead Acid Batteries

Zhongneng Chengyu Power Co., Ltd specialized in export storage battery, UPS, inverter, solar power system and so on, rely on abundant technical strength, full support of our customers and careful and strict management, our products are safe and sealing technology levels are industry-leading....

Product Details

As SLA Lead Acid Batteries system with the longest history, lead–acid has been under consideration for large-scale stationary energy storage for some considerable time but the uptake of the technology in this application has been slow. Now that the needs for load-leveling, load switching (for renewable energies), and power quality are becoming more pressing, the development and application of appropriate forms of lead–acid battery is proceeding with more purpose.

Battery knowledge


There are several factors that should be taken into account when determining the total cost of ownership over the life of the battery.


1.Price: A battery with a low price is always attractive, but if low price comes

at the expense of quality and battery life, the need for frequent battery replacements

could boost the cost over time. That’s why it’s important to consider issues other than

price when making the decision.

2.Capacity: Battery capacity is important because it’s a measure of the amount of energy

stored in the battery.

3.Voltage: The battery bank voltage must be considered to ensure it matches the system requirements. The battery bank voltage is often determined by the inverter specifications

if installing a DC-to-AC system or by the voltage of the loads in a DC system.

4.Cycle Life: The most critical consideration is cycle life, which provides the number of discharge/charge cycles the battery can provide before capacity drops to a specified

percentage of rated capacity. Batteries from different manufacturers may have the same

capacity and energy content and be similar in weight. But design, materials, process and

quality influence how long the battery will cycle.
