12V 7.5Ah Valve Regulated Lead-Acid Battery NP12-7.5 AGM Maintenance-free for Razor Scooter Solar System

12V 7.5Ah Valve Regulated Lead-Acid Battery NP12-7.5 AGM Maintenance-free for Razor Scooter Solar System

Features:

1. Valve-controlled design: When the internal pressure of the battery is too high, the safety valve automatically opens to exhaust and prevent expansion; when the pressure is normal, it remains sealed to prevent electrolyte leakage.

2. No need to add water: The electrolyte is adsorbed in the AGM (ultrafine glass fiber) separator, there is no free liquid, and no distilled water needs to be added during use.

3. Adsorption-type glass fiber separator: The electrolyte is fixed in the pores of the separator, with strong vibration resistance and suitable for mobile environments.

4. Lean liquid design: The amount of electrolyte is precisely controlled to reduce internal resistance and improve charging efficiency.

5. Sealed structure: The oxygen and hydrogen generated during charging are compounded into water inside, and almost no gas escapes.

6. Leak-proof design: There is no risk of electrolyte leakage, and it can be installed at multiple angles (not inverted).

7. High discharge rate: Supports high current discharge (such as car starting, UPS emergency power supply).

8. Low self-discharge: The monthly self-discharge rate is about 3%~5%, and the storage time is longer than that of ordinary lead-acid batteries.

9. Wide temperature adaptability: The operating temperature range is usually -20℃~50℃, and some models can be expanded to a wider range.

10. Cycle charge and discharge resistance: The deep cycle life can reach 300~500 times (under DOD 50%).

11. Anti-sulfurization: AGM technology reduces plate sulfidation and extends service life.
