SAFETY PRECAUTIONS
Although all valve-regulated cells have the electrolyte immobilized
within the cell, the electrical hazard associated with batteries still
exists.
Work performed on these batteries should be done with
the tools and the protective equipment listed below. Valve-
Regulated cell installations should be supervised by personnel
familiar with batteries and battery safety precautions.
WARNING: Risk of fire, explosion or burns. Do not disassemble,
heat above 40°C, or incinerate.
Protective Equipment
Although VRLA cells can vent or leak small amounts of electrolyte,
electrical safety is the principle but not the only concern for safe
handling. Per IEEE 1188 recommendations, the following minimum
set of equipment for safe handling of the cells and protection of
personnel shall be available:
1.
Safety glasses with side shields, or goggles, or face shields
as appropriate. (Consult application specific requirements)
2. Electrically insulated gloves, appropriate for the installation.
3. Protective aprons and safety shoes.
4. Portable or stationary water facilities in the battery vicinity for
rinsing eyes and skin in case of contact with acid electrolyte.
5. Class C fire extinguisher.
6. Acid neutralizing agent.
7. Adequately insulated tools (as defined by ASTM F1505 “Standard
Specification for Insulated and Insulating Hand Tools)
8. Lifting devices of adequate capacity, when required.
Procedures
The following safety procedures should be followed during
installation:
(Always wear safety glasses or face shield when working on or
near batteries.)
1. These cells are sealed and contain no free electrolyte. Under
normal operating conditions, they do not present any acid dan-
ger. However, if the cell jar or cover is damaged, acid could be
present.
Sulfuric acid is harmful to the skin and eyes. Flush
affected area with water immediately and consult a physician if
splashed in the eyes. Consult SDS for additional precautions
and first aid measures.SDS sheets can be obtained at

2. Prohibit smoking and open flames, and avoid arcing in the
immediate vicinity of the battery.
3. Do not wear metallic objects, such as jewelry, while working on
batteries. Do not store un-insulated tools in pockets or tool belt
while working in vicinity of battery.
4. Keep the top of the battery dry and clear of all tools and other
foreign objects.
5. Provide adequate ventilation (per IEEE standard 1187 and/or
local codes) and follow recommended charging voltages.
6. Never remove or tamper with the pressure relief valves.
Warranty void if vent valve is removed.
7. Inspect all flooring and lifting equipment for functional adequacy.
8. Adequately secure battery modules, racks, or cabinets to the floor.
9. Connect support structures to ground system in accordance
with applicable codes.

RECEIVING & STORAGE
Receiving Inspection
Upon receipt, and at the time of actual unloading, each package should
be visually inspected for any possible damage or elec-trolyte leakage.
If either is evident, a more detailed inspection of the entire shipment
should be conducted and noted on the bill of lading. Record receipt
date, inspection data, and notify the carrier of any damage.
Unpacking
1. Always wear eye protection.
2. Check all batteries for visible defects such as cracked containers,
loose terminal posts, or other unrepairable problems. Batteries
with these defects must be replaced.
3. Check the contents of the package against the packaging list.
Report any missing parts or shipping damage to your East Penn
agent or East Penn Mfg. Co. immediately.
4. Never lift the batteries by the terminal posts.
5. When lifting batteries, the proper equipment is needed such as a
forklift or a portable crane. Always check the lifting capacities of
the equipment being used and never lift more than one cell at a
time by the handles in the metal sleeve.
Storage
1. Cells should be stored indoors in a clean, level, dry, cool location.
Recommended storage temperature is 0°F to 90°F (–18°C to 32°C).
2. Stored lead cells self discharge and must be given a boost
charge to prevent permanent performance degradation.
0°F to 77°F (-18°C to 25°C) storage:
Batteries should be recharged six months from date of manufacture.
>77°F (25°C) storage:
Use the chart below for recharge intervals. Voltage readings
should be taken on a monthly basis. Cells that reach 2.10V per
cell or less should be recharged regardless of scheduled interval.
Record dates and conditions for all charges during storage.
3. If a boost charge is required; the recommended charge is 24
hours at a constant voltage equal to 2.40V per cell.
4. Do not store beyond 12 months.
INSTALLATION
General
Caution should be taken when installing batteries to ensure no damage
occurs. The battery string cabinet, tray, rack, etc. shall be inspected for
sharp edges that could cause damage to the battery casing. Batteries
shall not be dropped, slid, or placed on rough or uneven surfaces such
as tray lips or grated flooring. Mishandling of batteries could result in
equipment damage or human injury. East Penn will not be liable for
damage or injury as a result of mishandling or misuse of the product.
