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 free storage battery 2V400ah is used for solar energy systems/Ups/Telecom/Security systems/Emergency lighting and so on.
1. Don't near the hot source and don't under the sunshine.
2. Don't charge in the sealed container.
3. No short circuit. It should be addition charge if you don't use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.
4. Don't store in the space of acid gas.
5. You should be careful and regular check when use the battery. To avoid the battery don't work. You should change the battery if the capacity is not full or has been damage, especially after one year using.
6. Don't put the battery in the fire, or it will explode.
7. Please use cotton cloth to clean, if the battery is broken down and leak electrolyte. 8. Please wash your skin when touch the electrolyte.
9. Don't clean the battery by using the organic solution. (e. G. Petrol)
