Deep cycle battery: AGM battery adds tin is called deep cycle battery. Tin is good at electric conduction, and it not only makes the battery deep discharge , but also easily it is easily to charge. The design life is 8-10 years.

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 25degreewhich 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 degree 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.
