Lead and Gel Battery details
Valve regulated maintenance-free lead-acid battery characteristics:
Sealing: The battery compartment cover, pole double-sealed design to prevent leakage of acid, a reliable safety valve to prevent outside air and dust into the internal battery.
Maintenance-free: H2O regenerative capacity, high sealing efficiency of the reaction, the battery without pay or make up the acid to maintain throughout the process.
Safe and reliable: No acid overflow, reliable safety valves and explosion-proof device to the battery in the entire process more secure and reliable.
Long-life design: Computer refined the design of corrosion-resistant calcium pewter and other multiple alloy grid, ABS corrosion resistant material shell, a high sealing efficiency of the reaction, thus ensuring a long battery life.
(1) Weight, volume energy, the resistance of small, high output power.
(2) charge-discharge performance. The self-discharge less than a month and 2percent (20temperature).
(3) To restore good performance, deep discharge or charger failure, short circuit for 30 days, can still be charged to restore its capacity.
(4) without a balanced charge. Due to the resistance of individual cells, capacity, consistency float voltage to ensure that the battery in a floating state without a balanced charge.
Adaptable temperature: -25 ~ 50 temperature temperature under the security.
Easy to use and transport safety: Man charged the factory, there is no free electrolyte, the battery can be placed horizontally, and non-hazardous materials, water and land transportation.
