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,
ply 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
Mauritania Sealed lead acid battery 12v4ah can be used in building interphone, fire alarm system and so on.
