Proprietary Case, Cover, and Pressure Vent
We design and mold our own rugged polypropylene cases, vents
and covers in our on-site, state-of the-art plastics molding facility.
This provides ultimate control of our high performance designs,
quality and delivery to our manufacturing plant, assuring you the
highest quality battery and most reliable service.
Environment and Worker Protection
It’s nice to know that every possible safeguard was designed into
our process to protect our co-workers and the environment…
special safeguards that are exclusive to East Penn. One benefit
is assurance of a consistent source for batteries without fear of
governmental interference or delays.
Over 250 Quality Assurance Checks
Hundreds of quality checks are performed to assure total
confidence in the performance and life of our batteries.
For example:
• 100% Cycling. After initial charging, every battery
is discharged and then recharged at the factory. This
allows us to check the performance of the battery and give
it a second charge that equalizes the cells for improved
performance and longer life.
It’s interesting to note that, as a cost-saving measure, we use
the current generated during the initial discharge to recharge
other batteries in this computer-controlled process.
• Extended Shelf Stand Test. Before shipment, every
battery is required to stand for a designated period of time.
Beginning and ending voltages are compared. This extra
quality assurance step verifies that the critical pressure
control valves are functioning properly.
• Filling Weight Control. During this computerized process,
batteries are weighed before and after filling. This assures
that the exact amount of electrolyte is in each battery.
• Multi-Staged Filling and Vacuuming Process.
Every battery is filled and vacuumed several times during
this computerized process. Multi-staged vacuuming
assures complete electrolyte-to-plate interface, with no
power-robbing air pockets.
• Computerized Polarity Check. Every battery is checked by
computer for proper polarity.
• High Rate Discharge Test. Every battery is discharged at
approximately twice the rated capacity. A sensitive computer
monitors the voltage drop during this discharge to assure that
every battery performs as designed.
• Formed Element Inspection. Elements are assembled and
charged outside the battery container in a computerized
forming and drying process. This allows visual inspection of
every grid, plate, separator, and formed element before being
sealed inside the battery, assuring perfect cell elements with
longest life and highest performance.
• Tank Formed Plates. Voltage matched plates are critical
in standby applications. Forming each plate outside the
battery assures the highest quality, best matched plates
in the industry, and also allows a visual check before and
during assembly.
State-of-the-Art Technology
