Technical Features Benefit
Construction
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.
Electrolyte Suspension System
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.
Gas Generation
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.
Maintenance Free Operation
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.
Low Pressure Valve Regulated System
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.
Heavy Duty Grids
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.
Cyclic Service Life
More than 1000 discharge/recharge cycles can be realized
from Genesis NP batteries, dependent on the average
depth of discharge.
Float Service Life
Genesis NP Series batteries have an expected life span of
3 to 5 years in float service applications.
Self Discharge - Shelf Life
The self discharge rate of the Genesis NP series at room
temperature is approximately 3% of rated capacity per
month.
Operating Temperature
Genesis NP Batteries may be operated over a broad range
of ambient temperatures.
Deep Discharge Recovery
Genesis NP batteries recover their capacities even after
repeated deep discharges.
