BATTERY CHARGER

Instructions for Proper Use and Operation

WARNING

: HAZARD OF EXPLOSIVE GAS MIXTURE

When charging, a lead acid battery gives off hydrogen gas. The Gel type battery is a lead

acid battery with pressure relief type vents. Although it only gives off a small percentage of the

gas that a wet lead acid battery does, the following precautions should be observed:

1. Do not position your face over the battery, at any time while making connections.

2. Do not smoke, strike a match, or cause a spark in the vicinity of the battery during

charging.

3. Charge battery in a dry, well ventilated area.

4. Always unplug the AC supply cord before connecting or

disconnecting the charger leads

from the battery.

As additional protection from the hazard of electrical shock:

5. Do not expose the charger to rain.

6. Replace defective cords and wires immediately.

General Information for Charging Gel type Batteries

1. The time required to fully charge a battery will, of course, depend on the battery ampere

hour rating and the amount which the battery has been discharged. The charger ammeter

reading is your best indication of the battery's state of charge. In most cases, if the battery has

been discharged at all, the current meter will initially read close to 10 amperes. After 5 minutes

or so, the meter will drop to some lower level. This reading can be used as a rough guide to

determine the state of charge as shown on the front panel of the charger. Do not use the initial

reading obtained just after starting the battery charge. Some charger models will have a battery

fully charged light to indicate a full charge.

2. When fully charged, a new battery in good condition may cause the meter to "bounce"

around the "0" mark. This is normal and, in fact, indicates a true "full" charge.

As it ages or is wearing out, a battery may, in some cases, not drop below 1 ampere no matter

how long it is left connected to the charger.

If an audible click is heard when connecting the battery charger leads to the battery,

or if the meter is seen to move abruptly to the right (off scale), disconnect the charger leads

immediately. They have been connected in reverse polarity. Always connect the red (+ or

positive) clip to the positive terminal of the battery and the black (- or negative) clip to the

negative battery terminal.

4. In some cases, a severely discharged battery can cause the circuit breaker to open because

the battery is drawing more current than the charger can safely provide. If such is the case, it is

permissible to let the charger run for as much as 10 minutes with the circuit breaker turning the

charger on and off. The circuit breaker resets automatically. There is no reset button provided.
