Hogging
the Spotlight!
AND WHY NOT? FOR THE PAST 100 YEARS, NOBODY HAS
MATCHED THE WORK CAPACITY OF OUR IRONCLAD® BATTERIES.
The reason is simple: square tubes expose more surface area of the positive plates to the
electrolyte, which delivers higher sustained voltages (and higher work capacity) than in
round or flat plate designs, throughout the discharge cycle.
We call this the Ironclad® Effect, because it’s an advantage you get with every Ironclad
battery from EnerSys®. To find the Ironclad battery that’s right for your application,
call 1-800-EnerSys.
Ironclad® square tube
technology provides
22% to 67% more
positive surface plate
area, depending on
battery type and size.
Greater porosity of
fiberglass material
allows better electrolyte
circulation for higher
voltages.
Exclusively Square. Exclusively Powerful.
