I have a dual battery set up and controlled by a 4 position rotary perko switch with the following settings "off, bat1, both, bat 2"
The boat has been sitting in my garage for about 6 months and I want to use a trickle charge battery tender to bring the batteries up to full charge.
Do I need to disconnect the batteries and charge them individually or can I position the switch to "both" and charge them simultaneously? If I do charge them with the switch in "both" do I run the risk of damaging my electronics?
Thanks
