NP55-12 12V 55ah Automotive Battery/Electric Scootere battery/ multi-purpose VRLA Storage batteries/ Maintenance Free BatterySla Battery/Car battery/ Truck battery from china supplier
Features:
1. Completely sealed and water-free maintenance; No acid gas and environmental friendly.
2. It has adopted colloid electrolyte technology, avoiding density stratification problem of acid solution and eliminating plate corrosion and passivity caused by density stratification. It has a long float charge life. The designed life of 12V series small battery can reach up to 6 to 8 years ( environment temperature between 20° C to 25° C)
3. The battery is performed very well in cycling and recovery from deep discharge, especially in rainy days.
4. Good performance in cold environment and the battery capacity decreases little when using in low temperature.
5. Little self discharge because of the super-pure material and the low density of the electrolyte, it can be stored over 6 months.
Applications:
-1)Fire protection and security uninterruptible power supply
- 2)Electronic appliance and other backup power supply
- 3)Telephone and telecommunication equipment
- 4)Uninterruptible power supply systems for bank and hospital
- 5)Emergency lighting or small lamp fitting
-6) Electric power system
- 7)Security system
