solar battery; gel battery; deep cycle batteries
VRLA battery basically conquer some weakness of normal batteries, gradually replacing other type of sealed lead acid batteries. There are some features of VRLA battery:
(1)Maintenance free, no need add water, no need do proportion of acid and so on.
(2)High-current discharge performance, especially the excellent perfoemance of the impact of discharge.
(3)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.
(4)No leaking acid, no mist, non-corrosive, does not hurt, low pollution on environment.
(5)Long life, uesd under 25 ℃ floating charge, the battery life is up to 10-15 years.
(6)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.
(7)Don't exist the shortcoming of "memory effect"(referring to the cycle of work, the capacity loss) of nickel-cadmium battery.
