2V500AH maintenance free long cycle life lead acid battery used for Solar system/UPS Power/Telecom spower system
Inquire NowDescription
The 2V500AH maintenance-free long cycle life lead acid battery is designed specifically for use in solar systems, UPS power supplies, and telecommunications power systems. This advanced battery employs absorbent glass mat (AGM) technology, which allows for efficient gas recombination of up to 99%. As a result, it requires no electrolyte maintenance, eliminating the need to check specific gravity or add water. With its strong performance in both high and low temperatures, it enhances charging efficiency by reducing internal resistance and high-pressure water loss during operation.
Engineered for longevity, this battery boasts a design life of up to 15 years, thanks to its Pb-Ca multi-alloy corrosion-resistant grid. Additionally, its low self-discharge rate ensures that it retains its charge effectively over time. Environmentally friendly and non-polluting, the battery’s gas recombination technology prevents acid fog from escaping, making it a sustainable choice for various applications.
