EnerSys NP4-12 12V 4 Ah Sealed Lead Acid BatteryThe EnerSys NP4-12 is a 12 Volt, 4 Ah Rechargeable, VRLA Sealed Lead-Acid Battery with F1 terminals (0.187"). Typically found in Burglar Alarm Systems, Fire Alarm Systems and Access Control Systems, the EnerSys NP4-12 offers a reliable and convenient solution for backup battery power. The NP4-12 is an extremely versatile battery that can operate in any installation where a 12 Volt, 4 Amp Hour sealed lead acid battery is required.
Enersys' unique construction and sealing technique ensures no electrolyte leakage from case or terminals, making it one of the safest sealed lead-acid batteries available.
Electrolyte Suspension System
All NP batteries utilize EnerSys's unique electrolyte suspension system, incorporating a microfine glass mat to retain the maximum amount of electrolyte in the cells. No gels or other contaminants are added.
Control of Gas Generation
The design of EnerSys' NP Series batteries effectively incorporates the very latest oxygen recombination technology to control gas generation during normal use.
Low Maintenance Operation
Due to the perfectly sealed construction and recombination of gasses within the cell, the battery is almost entirely maintenance free.
The NP4-12 has F1 (.187") Terminals
Operation in any Orientation
The combination of sealed construction and Enersys' unique electrolyte suspension system allows operation in any orientation, with no risk of electrolyte leakage or loss of performance.
Valve Regulated Design
This battery is equipped with a simple, safe, low pressure venting system which releases excess gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge.
Lead Calcium Grids
The heavy duty lead calcium alloy grids provide an extra margin of performance and life in both cyclic and float applications and give unparalleled recovery from deep discharge.
Long Cycle Service Life
Depending on the average depth of discharge, over a thousand discharge/charge cycles can be expected.
Float Service Life
The expected service life is five years in most float standby applications.
The use of the special separator material provides a very efficient insulation between plates, preventing inter-plate short circuits and prohibiting the shedding of active materials.
