10.BATTERY CHARGING

10.1This charger adjusts the charging time in order to charge the battery completely, efficiently and safely. However, this section includes guidelines that can be used to estimate charging times.

10.2The amount of time required to fully charge a weak battery is dependant on a number of factors. In addition to the degree of discharge, these factors include the type and rated capacity, temperature, age of the battery, and amperage rating of the charger. At 70°F (22°C) the average discharged battery will be recharged as follows.

Charging Times are based on a 50% discharged battery - approx 12-12.2 volts.

NR = Not Recommended.

Charging times will vary with battery type and condition.

10.3Battery State – If a battery has only been slightly discharged, it can be charged in less than a few hours. The same battery could take up to 10 hours if very weak. The battery state can be estimated by using the built-in tester. The lower the reading the longer charging will take.

10.4.Battery rating – A higher rated battery will take longer to charge than a lower rated battery under the same conditions. A battery is rated in ampere-hours (AH), reserve capacity (RC) and cold cranking amps (CCA). The lower the rating the quicker the battery will be charged.
