● Designed life for floating charge is 5 years (20℃);

● Design with flat plate, GEL electrolyte and AGM separator technology;

● GEL electrolyte inside of battery keeps uniformity condition, battery is with excellent cycle life;

● GEL electrolyte has huge thermal capacity, thermal runaway phenomena never occur;

● High strength ABS material for container & lid;

● Wide temperature scope of application(-15~45℃).

●Best temperature of application(20±5℃);

● No leaking, safe and reliable;

● Standing or lying down for using, convenient to transport and install;

● Low self-discharge rate.

● Batteries should be stored in dry and clean warehouse which has good air exchange system. Batteries should avoid direct sunlight. Batteries should not be near to heat (such as radiator, the distance should more than 1m). Batteries should avoid any toxic gas and organic solvent.

● When the ambient temperature is less than 25℃, the longest storage life is 6 months. If ambient temperature is higher, the longest storage life varies as specified in below chart.

Storage Temperature (℃)≤2526~3334~40
Storage Time (Month)631

●Batteries should be recharged within the storage life or before using.

Charging methods: maximum charging current 57.5A, constant voltage 2.45±0.05V/cell (25℃);

Charging time: 15~20h; Temperature compensation coefficient: -5mV/℃/cell.


1) Communication Systems: Switch, Microwave Stations, Mobile Base Stations, Data Centers, Radio and Broadcasting Stations.

2) Motility Field: Robots, Electric Toys, Electric Tools & Portable Vacuum Cleaners.

4) EPS&UPS Systems

GEL batteries Benefits

1. Solve electrolyte stratification, sulfuric acid evenly distributed.

2. The silica gel electrolyte lead-acid batteries can be so deep discharge, thus greatly extending the cycle life of the battery.
3. The battery float current is small (about 1/3 AGM battery), the floating charge lower energy consumption, less warming, reduce battery thermal runaway risk.
4. low self-discharge rate of the battery.


1. Don’t near the hot source and don’t under the sunshine.

2. Don’t charge in the sealed container.

3. No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.

4. Don’t store in the space of acid gas.

5. You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.

6. Don’t put the battery in the fire, or it will explode.

7. Please use cotton cloth to clean, if the battery is broken down and leak electrolyte. Please wash your skin when touch the electrolyte.

8. Don’t clean the battery by using the organic solution. (e.g. petrol)
