Maintenance free, no need add water, no need do proportion of acid and so on.
High-current discharge performance, especially the excellent performance of the impact of discharge.
Self-discharge current, whose self-discharge daily rate 2% below under 25℃ which is about 1/4-1/5 of other types of sealed lead acid battery.
No leaking acid, no mist, non-corrosive, does not hurt, low pollution on environment.
Long life, used under 25 ℃ floating charge, the battery life is up to 10-15 years.
Compact construction, good sealing, the battery can be installed with other equipment in the same room, can be vertical or horizontal installation, small footprint, good vibration resistance.
Don’t exist the shortcoming of “memory effect”(referring to the cycle of work, the capacity loss) of nickel-cadmium battery.
Gel battery: AGM battery add gel is called Gel battery. Gel can avoid the water disappear when the valve release the gas. The gel is immobile, like gelatin, so it avoid the electrolyte to spilt out and corrosion the battery container. Even if they are cut open, the gel does not flow out of the battery. And also the gel also can protect the lead drop off the plate and delay the battery’s life. Gel batteries have a better resistance to extreme temperature changes, and are more vibration-resistant and shock-resistant than other types of batteries. The design life is 10-12years.
