The Battery Box seven stage smart charger is based on an advanced software program that monitors your
battery. Smart charge will select from the following cycles to optimise your battery’s performance.
Stage 1: Testing
Checks the battery capacity when the Battery Box is first turned on and predicts the hours left until fully
charged.
Stage 2: Charge
Commences recovery of battery back to peak voltage. Charges the battery up to a set voltage at which point
the battery is approximately 95% charged. Please note if you are using an external charging source (e.g. solar
panel) the screen will show ‘External Cycle’ after a few minutes of charging since the internal smart charger is
bypassed.
Stage 3: Bulk
Period just before boost when volts are constant.
Stage 4: Boost
Peak charge for maximum performance. Battery is charged for 1.5 hours at constant voltage. At the end of
boost the battery is 100% charged.
Stage 5: Resting
Allows the battery to consolidate after boost. The Battery Box ceases charging and allows the battery to rest
while allowing voltage to drop to float voltage.
Stage 6: Float
Maintains performance and prolongs battery life. Battery is continually monitored and voltage is maintained at
13.5V (13.7V for Lithium Phosphate) by automatically adjusting charge current for 500 hours.
Stage 7: Re-Awaken
Exercising the battery and avoiding sulphation build-up. After 500 hours of conditioning the charger
automatically returns to charge cycle.
Charging the Battery using Solar Panels (not supplied)
You can charge the battery via the external terminals using a solar panel array. To do this the isolator switch
must be in the ‘on’ position. The smart charge PCB will be bypassed with this configuration so there will be no
control over battery voltage. It is important to use an external voltage regulator (not supplied) when using solar
panels. The main data screen will show ‘External Cycle’ after a few minutes of charging. In this case the time
left figure is not displayed and the normal charging stages are bypassed.
Charging the Battery with an External Charger using the External Terminals or Accessory Sockets
Connecting the battery via the external terminals or accessory sockets to an external charging source can be
done as long as your charging source is regulated. The reason is because this method bypasses the internal
smart charger. The main data screen will show ‘External Cycle’ after a few minutes of charging.
