Installing Batteries
Multi-Stage Charging
Most Truecharge2 Battery Charger models have three outputs that share the
full rated current enabling it to charge three different batteries or battery
banks that either have the same chemistry or can tolerate the same charge
sequence and thresholds. The Truecharge2 Battery Charger can perform
either three-stage charging (Bulk, Absorption, and Float) or two-stage
charging (Bulk and Absorption).
IMPORTANT: The battery banks are not galvanically isolated from each
other. They share a common negative as shown in the diagram below.
The negative bus to chassis connection as shown below may not be suitable
in some applications.
