BATTERY CHEMISTRY SELECTION

The Multi-Chem function allows you to set the charging profile to suit each battery's
chemistry type (Lithium, GEL, AGM, WET and Calcium). This ensures correct and
thorough charging and maximises battery performance and battery life. The following
section describes the charge profiles for each chemistry type.
POWER SUPPLY (CONSTANT VOLTAGE OF 13.8 VOLTS)
This sets the charger in power supply mode giving a constant voltage of 13.8VDC.
This mode is best used where appliances are drawing power from the battery, for
example a Fridge.
LITHIUM (MAX VOLTAGE OF 14.2 VOLTS)
Charger will use a lithium-specific 5 stage charging algorithm.
GEL (MAX VOLTAGE OF 14.1 VOLTS)
This charge mode is designed for GEL batteries and has a maximum charge voltage
of 14.1V. Note that some GEL batteries require a higher charge voltage such as 14.4V.
The AGM mode can be used if this is required.
AGM (MAX VOLTAGE OF 14.4 VOLTS)
This charge mode is designed for AGM batteries and has a maximum charge voltage
of 14.4V.
WET (BULK AND ABSORPTION 14.7 VOLTS, RECONDITION UP TO 16 VOLTS)
This charge mode is designed for WET batteries and has a maximum charge voltage
of 14.7V during Bulk and Absorption stages and 16.0V during the Recondition stage.
CALCIUM (BULK AND ABSORPTION 14.7 VOLTS, EQUALISATION AND
RECONDITION UP TO 16 VOLTS)
This charge mode is best suited for Calcium batteries that have been deeply discharged
and require an equalisation charge to restore a full electrolyte reading. If the battery
requires a simple 'top-up', the WET charge mode can be used.
