CHARGING STEPS
USING THE G7200
Step 1: Diagnostics
Checks the battery voltage to make sure battery connections are good and the 
battery is in a stable condition before beginning the charge process.
Step 2: Recovery
Initializes the Recovery process, if needed, for deeply discharged or sulfated 
(desulfation) batteries by pulsing small amounts of current.
Step 3: Soft Start
Begins Bulk charging process with a gentle (soft) charge.
Step 4-7: Bulk
The Bulk charging process continues using Max Rate, High Rate, Medium 
Rate and Low Rate charges and returns 80% of battery capacity, indicated by 
the 25%, 50% and 75% CHARGE LEDs.
Step 8: Absorption
Brings the charge level to 90%. The battery charger will deliver small amounts 
of current to provide a safe, efficient charge and limit battery gassing. 
Step 9: Trickle
Battery is fully charged and ready to use, indicated by the 100% CHARGE 
LED being a solid Green. In this step, the battery charger will only deliver 
enough current to keep the battery full. If the battery tells the charger that 
more current is needed, the battery charger will switch to Maintenance.
Step 10: Maintenance
Continuously monitors the battery voltage to determine if a Maintenance 
charge should be initiated. If the terminal voltage falls below 12.8V (12V) and 
25.6V (24V), the charger will start the Maintenance cycle until voltage reaches 
14.4V (12V) and 28.8V (24V) and then discontinues the charge cycle. The cycle 
between Trickle and Maintenance is repeated indefinitely to keep the battery at 
full charge, without overcharging. The battery charger can be left connected
indefinitely.
Step 11: 13.6V Supply
The 13.6V SUPPLY mode is used for low voltage batteries, maintenance 
charging or as a power supply.
Step 12: 16V Boost
The 16V BOOST mode is used to recover battery capacity from a stratified 
(sulfated) battery by applying a specialized high 16.5V (17V Max) voltage 
to soften and melt down sulfate from the battery plates so that the material 
becomes usable again.

WICKED SMART FEATURE
AUTO-MEMORY. If at any time the battery charger is disconnected from 
its power source, either from a power loss or accidentally disconnecting 
the AC power plug from the electrical outlet, the battery charger will 
remember the previously selected charge mode when power is restored. 
The battery charger will automatically resume the charging process to 
ensure your battery is fully charged.
Now That’s Smart, Wicked Smart.™
WICKED SMART FEATURE
RECOVERY MODE. The Recovery Mode is a specialized charging step 
designed to rescue sulfated batteries by switching to a pulse cycle, 
if needed, to help regain battery capacity. The Recovery Mode is not 
always used. The Recovery Mode will only be initiated if the battery 
charger detects it can improve the battery’s performance.
