These

Hold or / and Press

modes are advanced charging modes that

require your full attention before selecting.
Using 6V NORM (Hold)

This mode is designed for 6V lead-acid batteries only. Consult the
battery manufacturer before using this mode.

Using 12V LITHIUM (Hold & Press)

This mode is designed for 12V lithium-ion batteries only, including
LiFePO4. Some lithium-ion batteries may be unstable and unsuitable for
charging. Consult the lithium battery manufacturer before charging and
ask for recommended charging voltage and current.

Using 12V REPAIR (Hold & Press)

This mode is for LEAD-ACID batteries only. It is an advanced battery
recovery mode for repairing old, idle, stratified or sulfated batteries.
NOT all batteries can be recovered. For optimal results, take the battery
through a full charge cycle, bringing the battery to full charge, before
using this mode. When this mode is chosen, do remember press Mode
button for choosing appropriate 12V Mode(s). One REPAIR cycle can take
up to

eight (8) hours

to complete the recovery process and will enter to

charge (8 steps charging cycle) when completed. This mode uses a high
charging voltage and may cause some water loss in WET cell batteries.
Plus, some batteries and electronics may be sensitive to high charging
voltages. To minimize risks, disconnect the battery from the vehicle
before using this mode.
