Description of 12v40ah battery
Advantage
1.The battery is full of power when it’s out of factory, no need to use liquid charge;
2.no memory, no need to discharge battery use, suitable for circuit design;
3.by high partition, adsorption and strong;
4.there is no flowing liquid (poor liquid), does not leak acid and free Upside down,
5.comply with environmental requirements, ease of use,
6.the use of lead-calcium alloys, battery self-discharge is very low, 7
.easy storage, less maintenance;
8.using ABS plastic shell and valve technology for safe use.
Application
The VRLA battery 12v40ah can be used in lamp, UPS, solar systems and so on.
