YUASA NP2.1-12 UPS Battery 12V 2.1AH Industrial VRLA Batteries Maintenance Free

Product Specification

YUASA NP2.1-12 UPS Battery 12V 2.1AH Industrial VRLA Batteries Maintenance Free Valve Regulated Lead-Acid

Valve-regulated lead-acid battery (VRLA) is a sealed maintenance-free lead-acid battery that reduces electrolyte loss through internal gas recombination technology. It is widely used in UPS, communication base stations, medical equipment, solar energy storage and other fields.

Specification:

1. No need to add water: Adsorbed glass wool (AGM) or gel (GEL) technology is used, the electrolyte is fixed and there is no risk of leakage.

2. Valve control design: When the internal pressure is too high, the safety valve automatically exhausts to prevent the battery from expanding or exploding.

3. Float charge life: usually 3~10 years (depending on the use environment).

4. Cycle life: 300~1000 times (deep discharge affects life).

5. Wide temperature operation: generally -20°C~50°C (gel batteries have better low temperature performance).

6. Good shock resistance: more suitable for mobile devices than ordinary lead-acid batteries.

7. Monthly self-discharge rate is 3%~5%, and it can still maintain a high power after being stored for half a year.

8. Backup power supply: Rapidly switch power supply when the city power is interrupted, requiring high-rate discharge capability.

9. Long-term floating charge: The battery is always in a fully charged standby state, requiring good floating charge resistance.

10. Temperature sensitivity: High temperature will accelerate aging, and the ideal ambient temperature is 20-25℃.
