AC Mains Charging
When the battery is less
than 9.5V, all loads are
disabled and the changing
current is limited to 10A.
The charger charges at this
rate until the battery voltage
is 10.5V
Solar Charging
When the battery is less
than 10.5V, all loads are
disabled and the changing
current is limited to 10A.
The charger charges at this
rate until the battery voltage
is 12.3V
During This mode the battery is
charged with a limit of bulk-
absorption current limit until the
battery voltage reaches bulk-
absorption voltage limit and charge
current of less than 2A. Then it
changes to Float mode.
This mode has a time limit of 5
Hours for a 100AH battery. If the
battery is not charged within this
time the charger will automatically
enter float mode. And will repeat
its-self in 6 hours time.
If charging from solar, the same
charging profile is followed – within
the limitations of the power
available from the panels at that
time.
Once in Float mode, the charge current is
limited to 10A and keeps the battery topped
up.
This mode has a time limit of 6 Hours for a
100AH battery. When this time is reached
the charger will go back to bulk absorption
mode.
Analyse Mode: BatteryPlus35 assesses the battery, sources and time continuously at all times. In analyse mode
the charger uses all information to decide what needs to be done next.
Note: Bulk and Float Charging times can be changed by changing the battery capacity using the Trek.

Bulk Absorption Mode
During this mode the battery is
charged with a limit of
bulk-
absorption current limit
until
the battery voltage reaches
bulk-absorption voltage limit
and
charge current of less than 2A.
Then it changes to Float Mode.
This mode has a time limit of 5hrs
for a 100Ah battery. If the battery
is not charged within this time, the
charger will automatically enter
Float Mode and will repeat itself in
6hrs time.
If charging from solar, the same
charging profile is followed –
within the limitations of the power
available from the panels at that
time.
