INTRODUCTION
The Auto Charge D2 is a triple battery system automatic battery charger de-
signed specifically for vehicles with a DDEC control and a separate engine
battery.
The engine battery on DDEC equipped vehicles presents a unique problem.
While it is desirable to have a charger to maintain this battery in a fully charged
condition, this battery is relatively lightly loaded. It is never required to operate
any of the vehicle mounted accessories and is rarely discharged.
however, may have multiple batteries which may be heavily loaded and require
considerable charging. The unequal loading may cause either overcharging the
engine battery or poor charger capacity utilization. The Auto Charge D2 spe-
cifically addresses this problem and automatically recharges and maintains both
vehicle and engine batteries.
The battery charger features are:
• Independent charge controls for each battery
• Electronic remote sensing of true battery voltages,eliminates the need
for sensing wires
• Automatic current limiting for both engine and vehicle batteries
• Built-in 5 ampere BATTERY SAVER
• Remote dual battery charge/condition indicator
• Power "ON" LED indicator
• BATTERY SAVER overload indicator
DESCRIPTION
Independent Charge Controls & Electronic Remote Sensing
The charger contains three independent charge controls, one for each battery.
This allows each battery to be independently charged while maintaining battery
isolation. Each battery voltage is remotely sensed, electronically, eliminating
the need for six sense wires. Each of the charge controls is completely auto-
matic and stops charging the battery when it is fully charged. There is no
trickle charge and therefore no danger of overcharging and water boil-off.
