Specialized solar battery is a kind of subdivision of storage battery according to different application fields. It is improved on the basis of ordinary storage batteries, adding SiO2 to the original technology to make the battery resistant to low temperature, higher safety, better stability and longer service life. Thus, it is suitable for use in bad weather, making the use of solar special batteries more targeted.

Product Advantage
Long life, using special lead-calcium alloy with good corrosion resistance made of pole plate, can have a long float charging life; using special colloidal electrolyte, increase the amount of acid in the battery, prevent the electrolyte from stratification, stop the pole plate branched crystal short circuit, to ensure that the battery has a long service life. Gel battery is based on the valve regulated sealed lead-acid battery technology to achieve long life. So 12V series gel battery design life is 6-8 years (25℃); 2V series gel battery design life is 10-15 (25℃).
Adoption of suitable positive and negative alloy formulations makes the batteries more suitable for the usage characteristics of deep charge/discharge cycles.
The design of colloidal electrolyte effectively inhibits the unavoidable electrolyte layering phenomenon in AGM valve regulated lead-acid batteries, and can better inhibit the shedding of active substances and the sulfation phenomenon of the pole plate, which slows down the degradation of the performance of the battery in the process of use and improves the deep charge-discharge cycling life of the battery.
Low self-discharge, which makes the battery have a longer shelf life and reduces the frequency and workload of battery maintenance during storage.
Low float charge voltage, small float charge current, high battery charging efficiency; good charging acceptance ability, strong undercharge recovery ability.
