3. PLACING IN SERVICE
Verify that the baery weight meets or exceeds
the minimum truck weight requirements. Allow the
baery to cool or warm to room temperature before
charging or adding water. Make sure the baery
charger is properly matched to the baery. Use a
charger with automac charger terminaon controls.
Open the vent caps from each cell and check to see
that the electrolyte level is above the top of the
separators. If it is obvious that the electrolyte has
spilled out of any cells, replace it with electrolyte of
the same specic gravity as found in the other cells of
the baery. Close the vent caps and give the baery a
freshening charge unl there is no increase in specic
gravity for three hydrometer readings taken at one
hour intervals.
During shipment of the baery, low temperatures
and/or normal shock and vibraon oen results in
a drop in the electrolyte level. If the level is below
the top of the separators, recheck it aer 3 hours of
charging. If the level remains below the top of the
separators, add water or electrolyte to the proper
level at the end of charging.
Following the rst week of service, the baery
should reach its normal operang specic gravity of
1.295 +/-0.005 at 77° F (25° C)
IF BATTERIES ARE NOT IN USE, KEEP THEM
CHARGED. CHECK THE SPECIFIC GRAVITIES
MONTHLY AND GIVE A FRESHENING CHARGE
(3 OR 4 HOURS AT THE FINISH RATE) IF THE
GRAVITIES HAVE FALLEN 0.030 OR MORE;
OTHERWISE GIVE A FRESHENING CHARGE
EVERY THREE MONTHS.
4. OPERATION
Baeries are rated in ampere-hours (Ahr) and are
selected to perform a specic workload within an
established period of me. Increasing the workload
or me period could result in over discharging, thus
shortening baery life. Limit discharging of the baery
(to 80% or less) so that specic gravies do not go
below 1.180. If truck operaon results in only paral
discharges (40% or less) and specic gravies are
1.250 or more at the end of the shi, recharging may
be deferred and the baery used for another shi,
providing the workload is not expected to increase.
Hydrometer readings and experience will determine
the frequency of charge intervals under these
circumstances.
A baery should always be recharged immediately
following a complete discharge. Never allow it to
remain in a discharged condion; otherwise,
permanent damage may result. A baery is designed
to be operated as follows:
8 hours discharge
8 hours charge
8 hours cool-down
Tubular baeries are designed and built to deliver 80%
of their rated capacity at 77°F (25°C) each cycle.
5. TEMPERATURE
In the operaon of move power lead acid baeries,
the electrolyte temperature must not exceed 110°F
(43°C). If the baery is connuously operated at or
above this temperature, the service life of the baery
will be severely diminished. Under normal operang
condions, baery electrolyte temperature should be
maintained between 60-100°F (15-38°C). Following
charging, the baery should be allowed to cool-
down or rest approximately 8 hours prior to another
discharge cycle.
If your baery is ever hot to the touch, allow it to cool
to room temperature before charging or discharging.
If a baery consistently operates at high temperatures
greater than 100° F (38° C), contact your local Stryten
Energy representave for service.
6. CHARGING
When recharging a fully discharged baery, the
starng charge rate may be 3 mes higher than
the nish charge rate. The charge rate should taper
down to the nish rate by the me the baery is
85% charged and may be even lower when fully
charged. High “on charge” temperatures or frequent
need for water addions are indicaons
of overcharging. Short running mes and/
