BATTERY TYPES
VRLA Gel Batteries
Valve-Regulated Lead-Acid (VRLA) Gelled-electrolyte
batteries offer many significant advantages over conventional “flooded” batteries. Gel batteries are spillproof* and
leakproof, and resist over-discharges that can shorten the
life of the battery.§
Gel batteries have a self-discharge rate of less than 1%
per month (at 68°F). They provide ample cranking amperage for quick, sure starts, and deliver longer trolling time
than comparable flooded models. Their VRLA design
minimizes gassing, making them safe to install around
people and sensitive electronic equipment. Gel batteries
offer a viable alternative when you can only choose one
battery. Gel batteries are maintenance-free.
§ Charge/Absorption/Equalize between 13.8 – 14.6 Volts
@ 77°F (25°C).
Float/Standby between 13.4 – 13.6 Volts @ 77°F (25°C).
Temperature corrected charging required.
* Rated non-spillable by International Commercial Airline
Association (ICAO), International Airline Transport
Association (IATA) and DOT definitions.

VRLA AGM Batteries
Valve-Regulated Lead-Acid (VRLA) Absorbed Glass Mat
(AGM) batteries use special absorbed electrolyte technology that is superior to flooded lead-acid batteries.
Fine, highly porous microfiber glass separators absorb
the electrolyte, increasing efficiency by lowering internal
resistance and boosting capacity.
Lower internal resistance also means that the batteries
can be recharged faster than conventional batteries,§
allowing the user to put them back into operation sooner.
The valve-regulated AGM battery virtually eliminates gas
emissions and acid leakage for longer and safer battery
operation. AGM batteries are also completely maintenance-free.

Flooded Batteries
Flooded lead-acid batteries are the most widely used
batteries both in automotive and marine applications.
Lead-acid batteries are usually less expensive than
either the Gel or AGM batteries, but do not provide the
same cycle life and convenience.
Most flooded batteries require maintenance. Electrolyte
levels must be maintained above the cell’s plates.

Deep Cycle Service
A deep cycle battery is called upon to deliver a long,
slow discharge of fewer amps...for several minutes or
hours...in a deep cycle application, such as running a
trolling motor or heavy marine accessory load (e.g.
depth finders, fish finders, radios, radar, lights, coolers,
house power, etc.).
In this case, the power comes from deep within the
plates, not merely off the surface as in starting.
Therefore, deep cycle batteries are specially engineered
with heavier, thicker plates with fiberglass reinforcement,
special power-producing active material and special
heavy-duty separators.
With these features, the battery can withstand the
potentially damaging effects of continual deep discharge
and recharge. The unreinforced, thinner plates of a starting battery cannot handle this constant deep cycling,
and will fail in short order.

BATTERY SAFETY
Proposition 65 Warning: Batteries, battery posts, terminals, and
related accessories contain lead and lead compounds, and other
chemicals known to the state of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling!
Always wear safety glasses when working on or near batteries.
BE CAREFUL! Batteries produce explosive gases. Keep sparks,
flames and cigarettes away from batteries at all times.
Lead-acid batteries are virtually 100% recyclable!
Be sure to return your used lead-acid battery to a
retailer. In most states it is illegal to discard a
battery in the trash.

Deep Cycle, Starting, Dual Purpose...
Which Should I Choose?†
Ideally, you could have one battery for starting and an
auxiliary deep cycle battery for the trolling motor and
accessories. If however, you can only have one battery
on board, the one you choose depends on the power
draw required.

Dual purpose batteries are ideal for applications that
require starting and deep cycle service. They deliver
powerful cranking amperage for easy starting, and
low amp draw service for reliable auxiliary power.
Dual purpose batteries are a perfect compromise
between the unique demands of starting service and
deep cycling, low amp draw service.
† Always be sure that the replacement battery CA and
CCA meet minimum engine starting requirements.

When a battery is called upon to deliver several hundred amps of power to the starting motor, the battery
must be able to deliver this power quickly...within a few
seconds. This power comes off of the surface of the
plates inside the battery. Therefore, a battery with more
plate surface area and less resistance will deliver power
quicker than one with less plate surface and high resistance.
That’s why starting batteries are made with thinner
plates...because you only use the power off the surface
of the plates for starting the engine.
For light to moderate-duty low amp draw service, choose the
dual purpose battery, specially designed to handle both starting
and cycling.
For heavy-duty cycling, choose the deep cycle battery.
This will give you enough cranking amperage to start your
engine, and the most reserve power to keep your trolling motor
and accessories running longer. Use the following convenient
chart to help you select a battery type appropriate for your
specific situation.
