Maintenance-fre NP12-9 12V 9Ah Vrla Battery New Original High Quality
►Brief Description
NP12-9 12V 9Ah Vrla Battery
1. Battery Type - 12V 9A Sealed Lead Acid Battery
2. High Impact Resistant Battery Housing Made of Non-Conductive ABS Plastic.
This material is highly resistant to shock, vibration, chemical corrosion and heat.
3. The acid inside the battery is absorbed by the plates and held in place by a very fine fiberglass mat. This combined with our battery's valve-regulated, spill-proof design ensures trouble-free, safe operation in any orientation.
The NP12-9 Battery is a maintenance-free valve-regulated battery that is ready for use with a simple one-time installation.

►Pay attention to when using valve-regulated batteries
1. Matching charger: Use a dedicated charger and strictly follow the charging voltage and current recommended by the manufacturer. Overcharging can cause gassing, swelling, and even explosion; undercharging can cause sulfidation and reduce capacity.
2. Floating charge voltage control: During long-term floating charge (such as UPS applications), the voltage must be accurate (usually 2.25-2.3V/cell). Too high voltage will accelerate aging, and too low voltage will cause capacity loss.
3. Temperature compensation: The charging voltage needs to be reduced in high temperature environments (the voltage drops by about 3mV/cell for every 1°C increase) to avoid thermal runaway.
4. Temperature environment: The optimal operating temperature is 20-25°C. When it is higher than 30°C, the life span is shortened by about 50% for every 10°C increase; the capacity drops significantly when it is lower than 0°C.
Heat dissipation and ventilation: Avoid confined spaces or direct sunlight, and leave heat dissipation gaps during installation to prevent heat accumulation.
►Safety precautions
1. Short circuit prevention: Tools must be insulated during installation to avoid metal contact with positive and negative electrodes causing short circuits.
2. Explosion-proof measures: Ensure that the safety valve is normal, and do not disassemble or block the exhaust hole. The charging environment must be ventilated to avoid hydrogen accumulation (although the amount of escape is small, prevention is still required).
3. Protective equipment: Wear gloves and goggles during maintenance. The electrolyte is corrosive, so rinse with clean water in case of leakage.
