LED INDICATORS

CLAMPS REVERSED (red) LED flashing:

The connections are reversed.

CHARGING (yellow/orange) LED lit:

The charger is charging the battery.

CHARGED/MAINTAINING (green) LED lit

:

The battery is fully charged and the charger is in maintain mode.

NOTE:

See the Operating Instructions section for a complete description of the charger modes.

Page 8

BATTERY TYPE BUTTON

Use this button to set the type of battery.

NOTE:

Each of the three settings apply for regular and deep-cycle batteries.

•

STANDARD –

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.

• AGM –

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 efficiency. 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.

•

GEL –

The electrolyte in a GEL cell has a silica additive that causes it to set up or stiffen. The recharge voltages on this type of cell are lower than those for other styles of lead-acid battery. This is probably the most sensitive cell in terms of adverse reactions to overvoltage charging. Gel batteries are best used in

VERY DEEP cycle application and may last a bit longer in hot weather applications. If the wrong battery charger is used on a gel cell battery, poor performance and premature failure will result.
