What is the difference between

gel cell and traditional wet batteries?

Wet cells do not have special pressurized sealing vents, as they do

not work on the recombination principle. They contain liquid elec-

trolyte that can cause corrosion and spill if tipped or punctured.

Therefore, they are not air transportable without special containers.

They cannot be shipped via UPS or Parcel Post or used near

sensitive electronic equipment. They can only be installed “upright.”

Wet cells lose capacity and become permanently damaged if:

– left in a discharged condition for any length of time (due to

sulfation). This is especially true of antimony and hybrid types.

– continually over-discharged, due to active material shedding.

This includes specially designed deep cycle wet cells,

but is especially true of automotive types.

Deep cycle antimony wet cells have seven times less shelf life as well.

Our gel cells have triple the deep cycle life of wet cell antimony alloy

deep cycle batteries, due to our unique design.

How do gel cells recharge?

Are there any special precautions?

While our gel cell will accept a charge extremely well due to its

low internal resistance, any battery will be damaged by continual

under- or overcharging. Capacity is reduced and life is shortened.

Overcharging is especially harmful to gel cells because of their

sealed design. Overcharging dries out the electrolyte by driving the

oxygen and hydrogen out of the battery through the safety valves.

Performance and life are reduced.

If a battery is continually undercharged, a power-robbing layer of

sulfate will build up on the positive plate, which acts as a barrier

to electron flow. Premature plate shedding can also occur.

Performance is reduced and life is shortened.

Therefore, it is critical that a charger be used that limits voltage

to no more than 14.1 volts and no less than 13.8 volts at 68°F.

Batteries used in float service should be charged at 13.8 volts.

For deep cycle service, a maximum voltage of 14.1 should be used.

The charger must be temperature corrected to prevent under- or

overcharging due to ambient temperature changes. (See Charging

Voltage vs. Ambient Temperature chart on page 11.)

Important Charging Instructions

The warranty is void if improperly charged. Use a good constant

potential, temperature corrected, voltage-regulated charger.

Charge gel cells to at least 13.8 volts but no more than 14.1 volts

at 68°F (20°C). Constant current chargers should never be used

on gel cell batteries.

Can gel cells be installed in

sealed battery boxes?

NO! Never install any type of battery in a completely sealed

container. Although the normal gasses (oxygen and hydrogen)

produced in a gel cell battery will be recombined as described above,

and not escape, oxygen and hydrogen will escape from the battery

in an overcharge condition (as is typical of any type battery).

For safety’s sake, these potentially explosive gasses must be

allowed to vent to the atmosphere and must never be trapped in

a hermetically sealed battery box or tightly enclosed space!

Can our gel cell be used as

a starting battery as well?

Our gel cell will work in SLI (Starting, Lighting and Ignition)

applications providing the voltage is regulated between 13.8 and

14.1 volts at 68°F. Most vehicle’s regulators are set higher than

14.1 volts. Therefore, the charging system must be adjusted for the

battery to recharge properly for best performance and longest life.

What do the ratings and specifications

signify for this line?

All ratings are after 15 cycles and conform to BCI specifications.

CCA = Cold Cranking Amps at 0°F (–17.8°C)

Cold cranking amps equal the number of amps of current a new,

fully charged battery will deliver at 0°F (–17.8°C) for thirty seconds

of discharge and maintain at least 1.2 volts per cell (7.2 volts for

a 12-volt battery).

CA = Cranking Amps at 32°F (0°C)

Same as above, tested at 32°F (0°C). (Note: All cranking ratings

are guidelines. Gel batteries are designed for cycling foremost.)

RC = Reserve Capacity at 80°F (27°C)

The reserve capacity is the time in minutes that a new, fully charged

battery can be continuously discharged at 25 amps of current and

maintain at least 1.75 volts per cell (10.5 volts for a 12-volt battery).

Minutes discharged at 50, 25, 15, 8 and 5 Amps

Minutes discharged is the time in minutes that a new, fully charged

battery will deliver at various amps of current and maintain at least

1.75 volts per cell. These are nominal or average ratings.

Ampere Hour Capacity at 20, 6, 3 and 1 Hour Rates

Ampere hour capacity is a unit of measure that is calculated by

multiplying the current in amperes (amps) by the time in hours

of discharge to 1.75 volts per cell. (These are nominal or average

ratings.)

EXAMPLE

10 amps for 20 hr. (10 x 20) = 200 Ah @ 20 hr. rate

8 amps for 3 hr. (8 x 3) = 24 Ah @ 3 hr. rate

30 amps for 1 hr. (30 x 1) = 30 Ah @ 1 hr. rate

Therefore, if you have an application that requires

a draw of 17 amps for 3 hours, you would need

a 51 Ah battery (@ 3 hr. rate)…(17 x 3 = 51).

However, the 51 amp hours delivered is

100% of the capacity of this 51 Ah battery.

Most system designs will specify a battery that will deliver a

minimum

of twice the power required. This means the battery

will discharge to 50% of its capacity. Using a 50% depth of

discharge (versus 80% or 100%) will dramatically extend the life

of any battery. Therefore, when helping to specify a battery for a

system, choose a battery with twice the capacity required for best

performance. If 50 Ah is required, specify at least a 100 Ah

battery.
