Instructions for Proper Use and Operation
WARNING: HAZARD OF EXPLOSIVE GAS MIXTURE
When charging, a lead acid battery gives off hydrogen gas. The Globe Gel type 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.
3.
!
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.
