be given an equalizing charge aer 50-100 hours of
operaon. If you are unsure of baery use hours, give
the baeries an equalize charge every two weeks.
6. AGV CHARGING
The baery/charger systems are “BALANCED” on each
AGV applicaon to maintain a design operang “STATE
OF CHARGE” within the baery. This state of charge is
dependent on such factors as:
• AMP-HOUR USED
• CHARGE TIME ALLOWED
• CHARGE CURRENT
Any plant operaons that will cause these factors to
deviate signicantly from the original design could
cause sucient baery/charger imbalance aecng
the baery life and performance. Plant deviaons such
as:
• Plant Shutdowns
• Extended Tesng
• Duty Cycle Change
• Vacaons
have the potenal to cause these imbalances. In
general, when opportunity charging is being used, any
nonoperaonal period of greater than 24 hours should
be controlled to prevent extended baery charging.
This can be accomplished in an AGV applicaon by
using the vehicle supervisory controls. Stryten Energy
recommends a 7 hours oncharge-17 hours o-charge
control for these 24-hour periods.
7. SAFETY
• Wear appropriate safety equipment when working
around electrically live baeries.
• The AGM200 baery can emit hydrogen gases under
some abnormal charging condions. Whenever
possible, charge in a well-venlated area and
keep open ames away from baeries. However,
normal warehouse venlaon is adequate for
normal AGM200 usage.
• Li baeries with a hoist, crane, li truck, or similar
equipment; move baeries on trucks, conveyors, or
rollers.
• Make sure equipment is of ample strength and
properly installed. Be sure to place a rubber mat
or similar insulang material across tops of baeries
without covers when handling. This will prevent
accidental shorts.
• Disconnect baery from the truck when performing
maintenance and repair on motor or electrical
system.
• Open, or “break” baery circuit before aempng
repairs to charging plug or receptacles.
• Familiarize yourself with baeries and rules for
charging and handling. Contact your local Stryten
Energy representave for informaon.
• Assign baery and charger care to properly trained
personnel. Review your company safety regulaons.
• Familiarize yourself with industry and government
guidelines (OSHA, ANSI, etc.) to help reduce
personnel accidents and equipment damage.
8. OPERATION
Baeries are rated in ampere-hour and are selected
to perform a specic workload within an established
period of me. Increasing the work load or me period
could result in over discharging, thus shortening
baery life. In general, all lead-acid baeries should
not be discharged to more than 80% of its six-hour
rated capacity. ONE BATTERY IS REQUIRED PER TRUCK
PER EIGHT-HOUR SHIFT. If a li interrupt is used or
installed on the li truck, a minimum interrupt voltage
of 1.86 VPC (under load), 2.02 VPC (open circuit)
mulplied by the number of cells, should be set to
avoid over-discharge of the baery.
Since your AGM200 is a VRLA baery, its state of
charge cannot be approximated by specic gravity.
However, average cell voltage (Volts per Cell) with
the baery under load can be used to approximate
the baery depth of discharge as shown in Figure 1.
Alternavely, the baery at 80% depth of discharge
will have an open circuit voltage equal to 2.02 VPC
mulplied by the number of cells in the baery.
