Power Supply Battery
Advanced gel energy storage battery with low-Calcium/high-Tin alloy grid, special formula active material, and proprietary gel electrolyte composition. Designed for long service life, low self-discharge, and reliable deep cycle performance.
Our GEL batteries use a low-calcium and high-tin alloy grid, providing excellent corrosion resistance, low gas evolution, and stable performance for long-term operation.
A specially formulated lead paste provides excellent charge acceptance, strong deep discharge recovery, and reliable cycle performance, making the battery suitable for demanding backup and deep-cycle applications.
The battery uses high-quality fumed silica-based GEL electrolyte to create a stable, non-layering electrolyte structure. This helps prevent electrolyte drying and supports consistent battery performance.
GEL electrolyte technology provides better heat dissipation than conventional AGM sealed batteries, helping reduce the risk of thermal runaway and maintaining reliable performance in demanding environments.
Designed for long-term operation, our GEL batteries offer excellent deep-cycle capability, a self-discharge rate of less than 1% per month, and a design life of over 10 years under standby use at 25°C.
Designed to perform reliably across a wide operating temperature range of -20°C to 50°C, making these GEL batteries suitable for a variety of industrial, backup power, and demanding environmental applications.
The completely sealed, maintenance-free design eliminates the need for regular electrolyte maintenance. High-purity raw materials, advanced manufacturing equipment, and 100% pre-delivery inspection ensure stable and consistent battery quality.

Suitable for solar photovoltaic systems, ensuring stable and reliable energy storage.

Designed for wind power generation systems for effective energy storage and dispatch.

Reliable backup power for telecommunications base stations.

Uninterruptible power supply applications requiring consistent backup power.

Emergency lighting and safety systems requiring reliable long-term standby power.

Railway signaling and control systems requiring high reliability.

Control power for power plants and substations.

Marine and offshore applications requiring vibration-resistant, sealed battery solutions.
Correction factor: 4mV/°C per cell
If the battery is fully discharged (100% depth), the typical charging time is 24-27 hours.
The battery is considered fully charged when:
