Do not charge frozen battery (batteries may freeze at temperatures of +20~F or colder if the state of charge is very low). If it is suspected that a battery is
Battery Fast Charger Recommendations
40-50 amperes minimum charge rate capability for discharged battery.
To prevent overcharge, a timer (one or two hour) or voltage regulator (18 volt maximum) to stop or reduce the charge rate as battery is recharged.
Ammeter or charge indicator. (Extremely cold and some completely discharged batteries may appear not to accept a charge on this meter. In
Automatic polarity protection. Some of these devices require some activating voltage to become operational, therefore, a by-pass or override
Charging Time Required
The time required to charge a battery will vary depending upon the following factors:
Size of battery - a completely discharged large heavy-duty battery requires more than twice the recharging as a completely discharged small
Battery temperature - a longer time will be needed to charge any battery at 0~F than at 80~F. When a fast charger is connected to a cold battery,
Charger capacity - a charger which can supply only 5 amperes will require a much longer period of charging than a charger that can supply 30
State of charge - a completely discharged battery requires more than twice as much charge as a half-charged battery. Because the electrolyte is
Battery chargers vary in the amount of voltage and current they provide. Thus, the time required for the battery to begin to accept measurable charger
REMEMBER, EVEN WITH CHARGER ON HIGHEST SETTING, IT MAY BE SEVERAL MINUTES BEFORE CHARGING CURRENT IS
Observe indicator for presence of green dot. If not visible, charge battery prior to testing.
Observing polarity, connect a voltmeter and a battery load tester across battery terminals.
Apply a 15 amp load or turn on headlamps for 15 seconds to remove surface charge from the battery. Remove the load.
Wait 15 seconds to let battery recover and apply load. See specifications for proper load.
Read voltage after 15 seconds with specified load applied, then disconnect load.
If voltage does not drop below the minimum listed in the Load Test Chart, the battery is good and should be returned to service. (The battery
If the battery passes the load test, its in good condition. No further tests are necessary. If it fails the load test, check further to see whether it should
