As there's a topic going one here. I'll ask the question.
I get what MB is saying about the charger putting charge into both batteries. My problem is that currently I have 2 different chemistry batteries aux is agm and starter is calcium. I know that I need to have different settings for each when charging, but when the charger is connected it's charging both as one system. Will putting an isolater in like the one pictured work. If I have it off/closed and the charger is connected to the aux it will only charge that one and when connected to the starter will only charge the starter?
Is that right..
When the starter needs to be replaced what is recommended so it will match the aux.
Thanks
Guys

Am I over thinking this.
Surely there are people with 2 different batteries that plug a charger in and just charge.

No , I charge them independently because a Calcium needs up to 16 v to charge properly and remove stratification where as the Agm shouldn’t go above 14.8 or you risk damage to it.
If the batteries are already charged and you want to just maintain them while not in use then being connected will be fine ,but charge on the AGM setting

Thanks mate.
Batteries are charged, cars driven everyday. I was told to throw a charger on them every 3-6 months to keep them healthy extend their lives.
Think I'll still go with the isolater.

Agree with Yeti's Best for independent charging. IMO, Good idea to occasionally charge your Calcium battery up to its 100% SOC voltage (eg: 16volts) if you are not already doing it as the alternator in the vehicle would be designed for FLA charge regime and would not reach the Calcium max charge voltage.
Also, have read that AGM have a lower float voltage than FLA. I guess AGM batteries would be adversely effected on long trip sitting at higher float voltage especially in prolonged hotter operating conditions (somthing to consider).
The isolator you illustrated would work but I would prefer to use some thing like a red keyed operated one (eg: Airflow and need only on auxillary):

Every car owners manual that I have read over the years actual says to charge the battery to help extend there lives.
But yes it is always good to keep them topped up
