Charger and Battery: General Information
Battery
The battery has an internal fuse for protection and is not serviceable.
Replacement of the battery is required to fix a blown fuse. To verify there is a
blown fuse, test the circuit on the battery between the positive and negative
circuits.
The LED status bar on the battery will shows the current charge level. When
the button is pressed, the lights should first cycle through all lights, then end on
the light showing the amount of charge. If no lights come on when the button is
pushed, the module in the battery is failed, replace the battery.
The battery will go to sleep after a short period of time. The power head or
charger will wake up the battery via the communication line, allowing operation
of the mower.
Charger
The charger has an internal fuse for protection and is not serviceable. When
there is a blown fuse, lights will not turn on.
The charger will only charge when the battery is in the temperature ranges
of 41–104º Fahrenheit (5–55º Celsius). If the battery is installed over the
temperature range, the charger will attempt to cool the battery before charging.
The charger starts the charge at 0.8 amps until the battery reaches a desired
temperature, then the charge goes up to 2.0 amps.
If a battery is above the allowable charging temperature range or stored in
temperatures above the allowable charging temperature range, the charger
will attempt to cool the battery with an internal fan if it is over the charging
temperature range when the battery is placed on the charger. If the temperature
is not cooled below the allowable range in two hours, the charger will stop the
attempt to charge. To restart the process, un-dock and re-dock the battery. If
the battery is below the allowable charging temperature range or stored in
temperatures below the allowable charging temperature range, the charger will
wait two hours after the battery is placed on the charger. If the battery does not
warm in the two hours, the charger will stop attempting to charge. Unlike hot
temperatures, the charger has no means to warm the battery. To restart the
process, un-dock and re-dock the battery.
When the battery is installed in the charger, the battery State Of Charge (SOC)
lights will cycle. If the SOC button was pressed shortly before the battery is
placed on the charger, the lights will not cycle again when the battery is placed
on the charger.
The charger light will blink green when it is charging and the battery voltage
is below 90%. The charger light will change to solid green when the battery
voltage is charged over 90% and the charger will continue charging to 100%.
If the battery was placed on the charger when the voltage was already above
90%, the charger will not initiate the charge process to 100%. The charger light
will be solid green.
The charger is not a trickle type charger, as found with lead acid batteries. This
type of continuous trickle charging at the end of charge will damage a lithium ion
battery.
