BATTERY TYPE BUTTON
Use this button to select the battery type.
– Used in cars, trucks and
motorcycles, these batteries have
vent caps and are often marked “low
maintenance” or “maintenance-free”.
This type of battery is designed to
deliver quick bursts of energy (such as
starting engines) and has a greater plate
count. The plates are thinner and have
somewhat different material composition.
Standard batteries should not be used for
deep-cycle applications.
– The Absorbed Glass Mat
construction allows the electrolyte to
be suspended in close proximity with
the plate’s active material. In theory,
this enhances both the discharge and
recharge efciency. The AGM batteries
are a variant of Sealed VRLA (valve
regulated lead-acid) batteries. Popular
uses include high-performance engine
starting, power sports, deep-cycle, solar
and storage batteries.
