Maintenance free storage battery 12v4ah is used for building interphone, fire alarm system ,UPS and so on.
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.
Maintenance and Attention Matters
1.Battery is not allowed close to Tepid source or basked under the sun for a long time.
2. No charge in the obturate container
3. No short circuit. Battery should be stored full of electronic when not in need,and the battery should be charged every three months in order to avoid the irreversible sulphation. When battery case bursts or electrolyte leaks, battery should be changed lest the acid
4. No battery in environment with the acid gas.
5. When battery is used as the backup battery, be careful and check it at regular time to avoid the damage battery. Especially the battery beyond one year should be checked in time, and change the less capacity and scrapped battery.( some batteries maybe have voltage but no current; some batteries maybe have current but no voltage; some maybe have both but less capacity: all these conditions cannot meet the work,reach the power-on time. Do not for the small battery,cause the huge losses )
6. Forbidden battery in the fire, otherwise it will cause an explosion.
7. When battery cracks or electrolyte leaks, please use cotton cloth clear it. When skin contacts to the liquid, please wash with fresh water immediately. See doctor if serious.
8. No wash on the surface of the battery with the organic solution.
