EnerSys NP4-6 6V 4Ah Sealed Lead Acid BatteryThe EnerSys NP4-6 is a 6 Volt, 4 Ah, Rechargeable VRLA Sealed Lead-Acid Battery with F1 (.187") terminals. The NP4-6 is most commonly found in Burglar Alarm Systems, Fire Alarm Systems and Access Control Systems as a Rechargeable Backup Battery for maintaining power during inconsistent power surges and power outages. The NP4-6 is the best choice when looking for a 6 Volt, 4 Amp Hour battery, regardless of the application.
Enersys' unique construction and sealing technique ensures no electrolyte leakage from case or terminals.
Electrolyte Suspension System
The NP4-6 utilizes EnerSys's unique electrolyte suspension system which incorporates a microfine glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells. No gels or other contaminants are added.
Control of Gas Generation
The NP4-6 harnesses the very latest oxygen recombination technology to effectively control the generation of gas during normal use.
Low Maintenance Operation
Due to the perfectly sealed construction and the recombination of gases within the cell, the battery is almost maintenance free.
NP batteries are manufactured using a range of terminals which vary in size and type.
Operation in any Orientation
The combination of sealed construction and Enersys' unique electrolyte suspension system allows operation in any orientation, with no loss of performance or fear of electrolyte leakage.
Valve Regulated Design
The batteries are 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 upon 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 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.
