Connecting 2 batteries together
I have space for 2 batteries where I currently have one. The one I will be adding is identical, except it is about a year older. Am I right, I need to daisy chain them?

- There are a lot of myths about paralleling batteries.
For the most part the only thing you need to concern
The Connecting cables need to be large enough (Same as the cable that runs off to who knows where)
And the polarity.
Most everythign else the batteries will work out by themselves
In some very high current installs there is more (Load Balance) But you are into the hundreds of amp loads before that's a concern.
With GC-2's there are additional concerns but since you are not going that route. That is all folks. Dutch_12078 wrote:
No... Two 12-volt batteries must be connected in parallel to still supply 12 volts, but at twice the amp/hours. "Daisy chained" would supply 24 volts, possibly burning out most of your 12 volt devices.
Well in electrical terminology for daisy chain in residential IS parallel connections.
But potato pototo.
Yes parallel them. Not series.- No... Two 12-volt batteries must be connected in parallel to still supply 12 volts, but at twice the amp/hours. "Daisy chained" would supply 24 volts, possibly burning out most of your 12 volt devices.
