DOL Series Gel Lead-Acid Batteries（2V）

Product Features：

• Adopts exclusive gel battery technology from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO).

• Excellent energy storage performance with high reliability.

• Sealed maintenance-free battery; no water topping-up required throughout its service life.

• Rated Capacity: DOL12V Series: 24～280Ah @C20; DOL2V Series: 70～3250Ah @C10.

• Design service life at 25°C: Over 16 years for the DOL12V Series, over 20 years for the DOL2V Series.

• Suitable for frigid or high-temperature environments with outstanding performance across extreme temperatures; operates normally within -40°C ~ +55°C.

• Housing Material: ABS (UL94-HB, UL94-V0 optional); PP material is also available as an alternative.

• Special formulation enables internal gas recombination with an extremely low gassing rate.

• Ultra-low self-discharge rate; no recharging required after two years of storage at 20°C.

• Designed in compliance with IEC60896-21/22 and AS40861(1993) standards.

• 2V batteries meet the requirements of DIN 40742.

• Strong charge acceptance enables short charging times.

• Deep discharge resistance delivers excellent cycle life.

• Fully recyclable.

Technical Structural Features：

• Electrolyte: Solid gel electrolyte with no fluid flow and zero leakage. It prevents electrolyte stratification and effectively slows sulfation of active materials to extend battery service life.

• Plates: Tubular or pasted plate design manufactured from high-purity lead with purity exceeding 99.994%, offering superior corrosion resistance and longer service life.

• Battery Jar & Cover: Made of ABS material with great corrosion resistance and impact resistance for enhanced safety and reliability.

• Separator: Special PVC-SiO₂ separator dedicated for gel batteries, which effectively prevents short circuits caused by lead sulfate piercing the plates and improves overall battery safety and reliability.

• Terminal Sealing: Embedded copper-core lead-based poles with superior current carrying capacity and corrosion resistance. Unique pole sealing technology effectively eliminates acid creepage.

• Safety Valve: Stable opening and closing pressure with high reliability, preventing battery case bulging, cracking and electrolyte dry-out.
