that the charger is operating at peak amperage. If, after 5 minutes charging time, the ammeter reading has not

decreased, unplug the charger and discontinue the charging process.

• Using a voltmeter, determine the voltage of the battery and if it is under 12 volts, the battery is probably beyond 

repair or recharging, and will need to be replaced.

• If the voltage is over 12 volts, reconnect the charger and resume the charging process for another 15-20 minutes. If, after

that time, the ammeter still has not moved towards a lower reading, repeat the voltmeter test. If the reading is still over 12

volts, there is a problem with the battery that requires professional service or replacement.

NO AMMETER READING

•  Make sure that the charger is powered by a "live" 110/120-volt AC outlet.
•  Unplug charger and check battery connections - ensure that there is a good connection with the battery terminal and/or

vehicle chassis.

• Check to be sure that the battery is not sulfated.
• Check that the correct charge rate has been selected for the battery being charged.
•  Ensure that enough charging time has been allowed for - check table in Appendix for approximate charging times.
• See Pre-charge Battery Activation

AMMETER DISPLAYS A READING, BUT BATTERY IS NOT ACCEPTING CHARGE

•  First, make sure that battery is capable of being charged - ensure that it is not sulfated or damaged.
•  Refer to Charging Time Table in Appendix to ensure that enough time is being allowed to charge the battery.

APPENDIX A – CHARGING TIMES

To calculate the approximate charging time required to fully charge a battery, it is necessary to determine the specific grav-

ity (or, percent of battery charge) using a hydrometer. Use this technique, if battery vent caps can be removed. Check each

cell. If there is one cell with a very low specific gravity compared to the other cells, there is probably a shorted cell in the

battery. Replace the battery.

The following chart converts hydrometer readings into percent of charge values.

The times shown in the chart above are approximate and refer to an average automotive battery. For smaller batteries, the

charge time should be adjusted using the formula shown below and adding 1 hour to the time calculated.

To estimate charging time for a discharged battery, divide the AH rating of the battery by the charge rate selected. This is

the number of hours required to recharge the battery. For example, a 50 AH (12 volt) battery is discharged (10 volts). How

long should it be charged at the 10 Amp rate? Divide the 50 AH by 10 AH. The answer is approximately 5 hours. Always

round up the charge time by 25% to ensure full charge. In most cases, battery recharge times will vary depending on the

age and condition of the battery. Smaller batteries should be charged at the lower rate (2 Amps) and add an extra hour to

charge time.
