2. Small service battery
PREREQUISITES
A dual battery system where the D250SE
charges a 40–300Ah service battery from a
generator which also charges a starter battery.
It is advantageous to use this installation when:
• The alternator is unable to deliver the desired
charging voltage.

BATTERY
TIP 2
If the alternator has external voltage detection
for the service battery, the voltage detection
wiring must be connected to the starter battery.
TIP 3
Complement the D250SE with a
SMARTPASS 120S if the service battery
capacity is greater than 100Ah or has parallel
consumption while charging is in progress. This
reduces the charging time.
