How to connect Two batteries and one Inverter

[brianmoser]

Hi.. I have two 12 V batteries and one 12 V inverter. I want to connect them with a switch so that I can change the battery its working with without having to re wire the whole thing again, to the other battery. What kind of switch do I need, and How do I connect it? Thank you

Can the inverter not work off charging batteries?

You could plug your charger into the inverter and connect it to the battery, it'd be permanently on charge then...

Maybe use a 3 position 2 pole changeover switch to...switch between the batteries, 3rd position being off.

the charger is built into the inverter. What Archy Styrigg said would be the ideal solution. Can Anyone post a link to one? I ve been googling but there seem to be so many such switches. I want the exact name/spec so I can buy the right thing when I go shopping. Thanks for the replies

What's the inverter model?

This gives a permanent connection for both batteries.

No need to disconnect.

the charger is built into the inverter, and there is only one set of wires coming out of it to the battery. It does the charging. still looking for a suitable switch. thanks for all the replies.
