DISCONNECTING A BATTERY FROM THE J35
To disconnect a battery from the J35:
1. Power off all loads connected to the J35, the easiest way is with the switch
connected to the J35 Load Isolation input
2. Turn off and remove all power sources (mains/solar/AUX) to the J35
3. Disconnect the battery’s negative (black) terminal from the J35 Batt-
connection point
4. Disconnect the battery’s positive (red) terminal from the J35 Batt+
connection point

CONNECTING MULTIPLE BATTERIES
Before connecting multiple batteries in parallel to the J35, check that all batteries
are:
1. Of the same type, for example, deep cycle AGM battery
2. Of the same capacity, for example, 100Ah
3. By the same manufacturer
4. Fully charged
5. Of the same age-never use batteries that differ in age
The recommended wiring for connecting multiple
batteries in parallel to the J35 is given in Figure 4.
Depending on system requirements, a qualified
auto-electrician may wire the batteries differently.
