THESE INSTRUCTIONS TO BE SHIPPED WITH BATTERY AND DELIVERED TO USER
AGM200
Previously Marathon Element.
1. RECEIVING BATTERIES
Immediately upon receipt of shipment, examine the
outside of the packing for signs of rough handling
before accepng baery from carrier. If there is
evident damage, the receipt should be signed and
both copies (carrier’s and receiving copies) marked
“Shipment Received Damaged”. The carrier should
be called immediately and asked to make a “Carrier’s
Inspecon for Damage Report”. If “concealed”
damage is later detected, the carrier should be called
immediately and requested to make a “Carrier’s
Inspecon for Concealed Damage Report”. Aer
inspecon by the carrier, arrangements should be
made with the local representave to have the baery
repaired before placing it in service.
2. PLACING IN SERVICE
All AGM200 baeries must be given an equalizing
charge prior to their use. To accomplish this, connect
the baery to an approved charger and commence
charging unl the automac charge control
terminates.
3. CHARGING*
The charger must be matched to the baery with
respect to voltage and ampere-hour capacity. The
charger must be an approved Stryten Energy charger
with a constant current-constant voltage-constant
current prole that has automac charge control
features and a nominal nish rate of 2 amps per 100
ampere-hours of rated capacity. The constant voltage
poron of the curve is 2.37 volts per cell. Under no
circumstances should you aempt to remove the
safety relief-valve vent cap. Such removal shall void
the baery’s warranty and seriously impair baery
performance.
4. COOL DOWN
When the baery reaches an 80% depth of discharge,
disconnect baery from the li truck and connect to
an approved Stryten Energy charger. The baery will
normally reach full charge in eight hours or less. Once
the charge is complete, the baery must be allowed to
cool down for eight hours. At a minimum, the baery
must be allowed to cool down for a me period equal
to the me period spent on charge.
5. EQUALIZING CHARGE
Each cell of a AGM200 baery may have slight
dierences in uniformity of construcon and content.
These slight dierences cause some cells to take
less charge than the other cells in the baery. To
bring the cells with a lower state of charge up to the
same level as the others, the baery is given
an “equalizing charge”. The baery should

be given an equalizing charge aer 50-100 hours of
operaon. If you are unsure of baery use hours, give
the baeries an equalize charge every two weeks.
6. AGV CHARGING
The baery/charger systems are “BALANCED” on each
AGV applicaon to maintain a design operang “STATE
OF CHARGE” within the baery. This state of charge is
dependent on such factors as:
• AMP-HOUR USED
• CHARGE TIME ALLOWED
• CHARGE CURRENT
Any plant operaons that will cause these factors to
deviate signicantly from the original design could
cause sucient baery/charger imbalance aecng
the baery life and performance. Plant deviaons such
as:
• Plant Shutdowns
• Extended Tesng
• Duty Cycle Change
• Vacaons
have the potenal to cause these imbalances. In
general, when opportunity charging is being used, any
nonoperaonal period of greater than 24 hours should
be controlled to prevent extended baery charging.
This can be accomplished in an AGV applicaon 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 baeries.
• The AGM200 baery can emit hydrogen gases under
some abnormal charging condions. Whenever
possible, charge in a well-venlated area and
keep open ames away from baeries. However,
normal warehouse venlaon is adequate for
normal AGM200 usage.
• Li baeries with a hoist, crane, li truck, or similar
equipment; move baeries on trucks, conveyors, or
rollers.
• Make sure equipment is of ample strength and
properly installed. Be sure to place a rubber mat
or similar insulang material across tops of baeries
without covers when handling. This will prevent
accidental shorts.
• Disconnect baery from the truck when performing
maintenance and repair on motor or electrical
system.
• Open, or “break” baery circuit before aempng
repairs to charging plug or receptacles.
• Familiarize yourself with baeries and rules for
charging and handling. Contact your local Stryten
Energy representave for informaon.
• Assign baery and charger care to properly trained
personnel. Review your company safety regulaons.
• Familiarize yourself with industry and government
guidelines (OSHA, ANSI, etc.) to help reduce
personnel accidents and equipment damage.
8. OPERATION
Baeries are rated in ampere-hour and are selected
to perform a specic workload within an established
period of me. Increasing the work load or me period
could result in over discharging, thus shortening
baery life. In general, all lead-acid baeries 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)
mulplied by the number of cells, should be set to
avoid over-discharge of the baery.
Since your AGM200 is a VRLA baery, its state of
charge cannot be approximated by specic gravity.
However, average cell voltage (Volts per Cell) with
the baery under load can be used to approximate
the baery depth of discharge as shown in Figure 1.
Alternavely, the baery at 80% depth of discharge
will have an open circuit voltage equal to 2.02 VPC
mulplied by the number of cells in the baery.

9. BATTERY DISCHARGE ALARM/MONITORS
Your AGM200 baery is equipped with a Baery
Discharge Alarm to protect your Marathon Element
baery from over-discharge. An intermient 80-db
alarm will start to sound whenever the baery’s
voltage drops to or below the alarm reference voltage
for a xed period of me. The alarm will stop if and
when the baery’s voltage recovers to above the
THE AGM200 BATTERY SHOULD NOT BE
DISCHARGED BELOW 1.86 VPC (UNDER
LOAD), 2.02 VPC (OPEN CIRCUIT) (80% DEPTH
OF DISCHARGE)
alarm reference voltage within a xed period of me.
The baery is at 80% depth of discharge when the
alarm sounds connuously. As soon as the alarm
begins to sound connuously, the baery should be
completely recharged using an approved charger
and proper charging procedures. Baeries may be
equipped with monitoring devices by Stryten Energy.
Damage to or tampering with these devices shall void
all warranes. Any addion of monitoring devices
axed to the baery, not authorized in wring by
Stryten Energy, shall void all warranes.
10. TEMPERATURE
Normal operang condions shall be between 60°F
and 100°F. Operang temperature above 100°F
will reduce the baery’s service life. Operang
temperature below 60°F results in less capacity and
special charging is required.
11. MAINTENANCE
Because this is a AGM200 baery, there is lile to
do regarding maintenance operaons. The top of
the baery should be kept clean and dry and may be
washed to remove any accumulated foreign maer. In
the unlikely event of an accidental contaminaon with
electrolyte or lead, contain the spill and nofy your
local Stryten Energy representave who is equipped
to handle any environmental concerns. Spill kits are
available from the Stryten Energy Parts Center by
calling [phone]. Never aempt to add water to
the baery - it has been designed to funcon without
any such addions over its enre life. As previously
noted, any aempt to remove the vent caps shall void
the warranty.
12. CHANGES IN OPERATIONS
If any me aer inial purchase you have changes to
your operang condions, such as extended shis,
increased loads or other changes that alter your inial
purchase condions, please contact your local Stryten
Energy representave immediately to ensure you are
properly equipped and are not aecng the life of the
baery.
