2: INTRODUCTION
Thank you for your purchase of East Penn's Deka Ready Power
Lithium-Ion Motive Power battery. Deka Ready Power is the ideal solu-
tion for powering Class I, II, and III forklift trucks in high intensity two
and three-shift operations. Its many benefits include:
• Available in a wide assortment of 24, 36, & 48 volts with UL listing
• Lithium Iron Phosphate ("LiFePO
highest performance and safest Li-Ion chemistry
• Lower overall operating and ownership costs - minimal kwh's
to recharge
• Very long cycle and calendar life
• Consistently high capacity run time and faster charging capability
• Stronger operating performance during lifting/driving (constant voltage
during discharging)
• Increased productivity with zero battery changes, saving money,
space, and staffing requirements
• The battery can be turned off when not in use, allowing for safe
transport of the lift equipment with battery installed
• No special safety considerations for fire suppression
• No hazardous waste/spills or neutralizing washes

3: Safety
NOTE:
All service work must be completed by an authorized Deka
service representative.
When used properly, The Deka Ready Power Li-ion Motive Power
battery is a safe, dependable source of electrical power. The materials
contained within this product may present a hazard or hazardous
condition if the integrity of the cell or battery is compromised.
Only trained and QUALIFIED personnel should install, use, or service
this equipment. Consult the Safety Data Sheet (SDS) for additional
precautions and first aid measures. The SDS can be obtained
at www.eastpennmanufacturing.com
3:2 Elements of Concern
There are five main potential hazards when not used and maintained
as designed in a Deka Ready Power Li-ion battery: electrolyte,
off-gassing, arc flash, shock potential, and weight.
1. Electrolyte: The electrolyte in a Li-ion battery plays a key role in
transporting the positive lithium ions between the cathode and anode.
The most commonly used electrolyte is comprised of lithium salt,
such as LiPF6 (an organic solvent), containing ethylene carbonate,
dimethyl carbonate, and diethyl carbonate. Electrolyte can be a safety
hazard since it contains flammable solvents. If the Deka Ready Power
is damaged or incorrectly charged, it may lead to explosion and fire.
Electrolyte in the presence of water will also produce Hydrofluoric
acid. Consult SDS for additional precautions and first aid measures.
2. Off-Gassing: Cells have pressure relief valves to vent excessive
pressure due to the breakdown of the electrolyte. This breakdown
may produce an "organic" smell (similar to a permanent marker) odor.
Allow off-gassing to dissipate before servicing a battery and contact
the local Deka Representative for further guidance.
3. Electricity: Electric shock hazard exists for persons who contact live
parts of batteries when the voltage is over 50 volts. The higher the
voltage, the greater the electric shock hazard. Do not touch battery
terminals while the Deka Ready Power is operating.
4. Arc Flash: The light and heat produced as part of an arc fault is a
type of electrical explosion or discharge that results from a connec-
tion through air to ground or another voltage phase in an electrical
system. Be sure to consult a hazard category classification table, like
that found in NFPA 70E. Table 130.7(C)(15)(a) lists a number of typical
electrical tasks by various voltage levels and recommends the cate-
gory of PPE that should be worn. The second method of selecting PPE
is to perform an arc flash hazard calculation to determine the available
incident arc energy. An industry manual from the Institute of Electrical
and Electronical Engineers (IEEE) labeled IEEE 1584 provides a guide
to perform calculations given the maximum fault current, duration
of faults, and other general equipment information is known. Once
the incident energy is calculated, the appropriate Personal Protective
Equipment (PPE) can be selected. Only personnel trained in NFPA 70E
and the Deka Ready Power should service the Deka Ready Power.
