CHARGING YOUR VEHICLE
New Battery Break in
New batteries require a break in period of up to 40-cycles. The batteries will not have their full capacity during
this break in period and may require longer charging times.
Charging Time
Average charging time is 8 to 12-hours. The time required to fully charge your batteries will vary depending on:
• Capacity of the batteries, higher capacity requires longer charge time.
• Output of the charger, higher output requires less charge time.
• Depth of discharge, the deeper a battery is discharged, the longer it takes to charge.
• Temperature, low temperatures require longer charge time.
It is not unusual for charge times to exceed 15-hours, especially with new batteries.
Industrial Charger Operation
If equipped with an industrial charger, it is either specified by or provided by the end user. Refer to the
operating instruction supplied with your charger or contact the charger manufacturer for more information.

HB series chargers use a semi-automatic charging system. The charger
will turn itself ON when the AC power cord is connected to the AC power source and
turn itself OFF when the batteries are fully charged. Refer to the data plate on the
charger for the voltage and type power required for the charger.
There is a series of LED’s on the faceplate of the charger that serve two functions:
1: Status of charge. The LED’s will display an approximate percent of charge
during the charging cycle. Refer to the table below.
2: Error condition. All three LED’s flashing is an indication of a charging problem (charger will also be
beeping). Refer to the
Charger Troubleshooting
section for information on error codes.
