SEALED VALVE REGULATED LEAD-ACID (SVRLA) GELLED ELECTROLYTE BATTERIES
WARNING: Always wear safety glasses when working around batteries! Keep sparks and flames away! The valve regulated pressure relief
valve should never be removed or loosened!
Above are examples of available designs. Contact your local sales representative for more information and proper selection.
1. Upon receipt of the PowrMate, if there are signs of rough handling,
or exposed electrolyte, or loose or missing vent(s),
file a claim with the carrier and advise your Deka representative.
2. Make sure that the PowrMate “SERVICE WEIGHT,” which is stamped
below the lifting hole in the steel tray, falls within the battery weight
range shown on the truck nameplate. East Penn Manufacturing Co.
cannot be responsible for determining that the battery weight is
sufficient to counterbalance your particular truck.
3. The batteries should receive a charge prior to placing the PowrMate
into service. The batteries shall be charged by using the supplied
on-board charger. The charge is complete when the charger
automatically terminates. No other charger should be used. Doing so
will void the warranty.
4. The batteries shall only be charged when the vehicle battery
discharge indicator is below 50% state of discharge. The charge
shall continue until the charger terminates the charge automatically.
The steel tray cover or the truck compartment should be kept open
during the entire duration of charge.
5. Measuring the open circuit voltage provides a way to determine the
state of charge of the batteries. The open circuit voltage shall be
taken with a voltmeter. To confirm 100% State of Charge, voltage
measurements should be taken no earlier than 4 hours after charge.
6. EPM recommends when lifting a PowrMate that an insulated lifting
beam be used. Also, make certain that the lifting hooks are the
correct size and are properly aligned with the holes in the lifting ears
of the tray prior to hoisting the PowrMate.
WARNING: Charging shall be performed by using only the supplied on-board charger for PowrMate. The valve-regulated vent should not be
removed. Removal of the vent will adversely affect the battery’s life and performance. The battery’s warranty will be void if these guidelines
are not followed.
INSTALLATION INSTRUCTIONS
1. The top of the batteries should be kept clean and dry at all times.
Simply clean the tops of the batteries with a damp cloth. The valve
regulated vent and shroud shall remain on the batteries at all times.
2. The cables and connectors should be inspected daily for exposed
copper wires, frayed or cracked insulation, loose connections, or
pitted contacts, and repaired as required.
3. Be especially careful to keep metallic objects off the top of the
batteries. Any metal touching two or more connectors may cause a
short circuit resulting in an arc or spark which ignite battery gasses
explosively.
