Battery Construction 4

Today’s Genesis®NP Battety series is

the culmination of more than ten

decades of battery manufacturing

experience. High energy density,

leak proof construction, excellent

performance in either float or

cyclic applications and long

service life combine to make the

Genesis NP Series the most

reliable and versatile maintenance

free rechargeable sealed lead acid

batteries available.

Construction

Electrolyte Suspension System

Gas Generation

Maintenance Free Operation

Low Pressure Valve Regulated System

The construction and sealing techniques of the Genesis NP

battery guarantees leakproof operation in any position

except inverted, with no adverse effect to capacity or

service life.

All Genesis®NP batteries utilize an electrolyte suspension

system consisting of a high porosity, glass fiber material

which in conjunction with plates, totally absorb and

contain the electrolyte. No silica gels or any other

contaminants are used.

Genesis NP batteries incorporate a built-in design that

controls gas generation and induces recombination of

more than 99% of gases generated during float usage.

There is no need to check specific gravity of the electrolyte

or add water to Genesis NP batteries during float service

life. In fact, there is no provision for this type of

maintenance.

All Genesis NP batteries are equipped with safety release

valves, designed to operate between 2 and 5 psi and

automatically reseal. Hence, there is never an excessive

accumulation of gas within the battery.

Deep Discharge Recovery

www.enersys.com

Heavy duty lead calcium tin alloy grids provide an extra

margin of performance and service life in either float or

cyclic applications, even after repeated over discharges.

More than 1000 discharge/recharge cycles can be realized

from Genesis NP batteries, dependent on the average

depth of discharge.

Genesis NP Series batteries have an expected life span of

3 to 5 years in float service applications.

The self discharge rate of the Genesis NP series at room

temperature is approximately 3% of rated capacity per

month.

Genesis NP Batteries may be operated over a broad range

of ambient temperatures.

Genesis NP batteries recover their capacities even after

repeated deep discharges.
