Yuasa’s unique construction and sealing technique ensures
no electrolyte leakage from case or terminals
Electrolyte Suspension System
All NP batteries utilize Yuasa’s unique electrolyte suspension
system incorporating 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 design of Yuasa’s NP batteries incorporates 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 gasses within the cell, the battery is almost maintenance
free.
Terminals
NP batteries are manufactured using a range of terminals which
vary in size and type. Please refer to details as shown.
Operation in any Orientation
The combination of sealed construction and Yuasa’s unique
electrolyte suspension system allows operation in any orientation,
with no loss of performance or fear of electrolyte leakage.
(Excluding continuous use inverted)
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. Note. On no account should the battery be
charged in a sealed container.
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.
Separators
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.
Long shelf Life
The extremely low self discharge rate allows the battery to
be stored for extended periods up to one year at normal ambient
temperatures with no permanent loss of capacity.

NP
Available in a wide range of sizes to suit general applications.
NPH/NPW
High performance batteries specially designed for applications
requiring high rate discharge, supplying up to 50% (NPH), (NPW)
more power (Watts) for short durations when compared to conventional
NP models.
NPC
Specifically designed to suit the arduous requirements of cyclic
applications allowing increased cycle life (at least double
that of conventional types). (NPC Shortform refers)
NPL
Long Life Model also to BS6290pt4 (FR Options)
Dedicated literature available on request. (NPL Shortform refers).
Applications
Yuasa NP batteries, having excellent deep discharge recovery
characteristics coupled with long life on float standby, are
ideal for numerous applications in both cyclic and standby modes.
For advice on the use of NP batteries in your particular application
please contact our Sales Office.
Charging For Float Standby Applications
Charged at 2.275 volts per cell continuous. The battery will
seek its own current level and float fully charged. However,
users should be aware that when charging from fully discharged,
the battery can draw an initial charge current of approximately
2cA. Care should therefore be taken to ensure that this initial
charge current (if ungoverned) is within the output capability
of the equipment. Final charge current at 2.275 volts per cell
is typically between 0.0005cA to 0.004cA.
Charging For Cyclic Applications
See cyclic recharge regime graph.
CAUTION
- Do not Short Circuit
- Do not charge in a sealed container
- Service life and operational characteristics will be affected
by temperature
- AC Ripple reduces service life.
WARNING!
The battery type NP65-12I must never be installed permanently
suspended by their handles; they are not designed for this purpose.
