Cworth Gel Battery G-12V 100AH

Gel Battery G-12V 100AH

The Cworth Energy G-12V 100AH is a sealed maintenance-free GEL VRLA battery engineered for solar energy storage and backup power. Its gelled electrolyte delivers excellent deep-cycle performance, strong resistance to over-discharge and a low self-discharge rate below 3% per month, so it can be stored for over six months at 25°C. With a 100Ah capacity, 1000A short-duration discharge and approximately 5.0 mΩ internal resistance, it is an ideal, hassle-free choice for homes, telecom sites and small off-grid systems.

Gel Battery G-12V 200AH

The Cworth Energy G-12V 200AH doubles the stored energy of the 100AH model for larger residential and commercial storage banks. Built with high-purity GEL technology, it offers up to 2000A of surge discharge, a lower ~4.0 mΩ internal resistance and a wide operating temperature range. Fully sealed and maintenance-free, it withstands demanding cycling duty and pairs perfectly with solar arrays, inverters and backup systems where dependable long-life storage matters.

Why Cworth GEL

Gel battery advantages

Safe & long life cycleDeep-discharge-tolerant silica-gel electrolyte greatly extends cycle life.
Even acid distributionAcid is fixed in the colloid — no stratification or tilt; mount vertically or horizontally.
Efficient float chargingFloat current about 1/3 of an AGM battery — less heat and lower thermal-runaway risk.
Low self-dischargeSuppresses spontaneous PbO reduction, so it stays charged in long-term storage.
Eco-friendly & economicalNo acid mist, no leakage, no combustion or explosion, no pollution in use.
Wide temperature rangeRuns reliably from -40°C to 65°C, easing hard starts in extreme cold and heat.
