Charging Stages
- Soft Start is used if a battery’s voltage is under 10.5V when
charging begins. It uses a low constant current to slowly bring
up voltage. This prepares a weak or neglected battery for the
Constant Current stage.
- Constant Current (sometimes called Bulk) is the main charging
stage. The charger puts out a constant current of 2A, its full power.
Battery voltage rises until the battery reaches the optimal charging
voltage CV* (See Voltage Table).
- Constant Voltage (sometimes called Absorption) is the second
charging stage. The charger regulates the current given to the
battery to maintain a constant voltage CV* (See Voltage Table).
As the battery nears a full charge, the current needed to maintain
this voltage decreases. Once the current falls below 0.5A (0.1A for
2012-AGM) the stage is complete.
- Battery Test is administered by reading your battery voltage
while resting the battery for 10 minutes. A voltage of under 12.5V
indicates a weak battery, under 11.5V indicates a shorted cell. The
battery is tested at completion of the Constant Voltage stage, and
every 12 hours while in Float.
- Float (sometimes called Maintenance) is the charger’s long term
stage. The charger can and should be left connected indefinitely.
This will keep the battery fully charged ensuring no sulfate can
form. The charger maintains float voltage FV* (See Voltage Table)
using very little power as it actively monitors the battery and adjusts
its output several times a second.

Additional Product Information
Indicator Light Features
- Power light is GREEN anytime the charger is plugged into AC Power.
- Battery Connection light is GREEN when the unit it is correctly connected to a battery. If the Battery Connection light is RED the polarity is reversed and the positive and negative terminals need to be switched. If the light remains RED after switching the connections, there is a short circuit.
- Battery Weak light is AMBER if the Soft Start mode is used or the battery fails a Battery Test. The indicator will stay on until the battery passes a Battery Test. A neglected battery can take over 2 weeks of desulfation to correct. If after 2 weeks it still reads as a Weak Battery, there is likely internal physical damage.
- Load light is AMBER if the charger is in Float and outputting 2A. This indicates a drain on the battery or a large battery that was not charged within the time limits. If possible remove any loads. When this light is on, the battery charge level lights correspond only to battery voltage, not charging stages.
- Bad Cell light flashes RED if the charger has not completed the Constant Current stage in 20 hours and battery voltage is under 11.5V ( Flashing), or if the battery is under 11.5V after a Battery Test ( Flashing). The charger shuts off output to avoid any damage to your battery. Loads or banks of batteries may trigger this mode if they are too large for this charger. Remove any loads and charge batteries individually.
- Testing light flashes BLUE when the unit is performing a Battery Test (see Charging Stages). BatteryMINDer® 2000 Series Rev. C-091911 Page 11 P/N VDC2000-MNL
- Desulfation light flashes BLUE any time the unit is desulfating. The BatteryMINDer desulfates any time it is outputting current.
- Temperature Compensation light is GREEN if the temperature is over 27°C/80°F, BLUE if the temperature is under 21°C/70°F. BatteryMINDer Model 2012 includes an ambient temperature sensor which allows it to vary the output voltage as necessary to properly charge your battery (-0.025 V/°C). Batteries charged at higher temperatures without compensation will overcharge and may outgas. Batteries charged at lower temperatures without compensation will undercharge allowing sulfation to build, possibly leading to the battery freezing. By using temperature compensation, the BatteryMINDer ensures your battery will never over or under charge, even in extreme conditions.
