Mixing AGM and Sealed Acid Batteries

I agree, it does not answer my underlying question of whether or not I can mix AGM with Sealed Acid Batteries. I was responding to whether there was a switch on the charger. It appears to be automatic. As I indicated earlier, I will need to check with Jayco to determine if the house charger charges the chassis batteries. Unless someone on this forum knows the answer.

Thanks

I think this is correct.

I just found this at the intelipower website:

NOTE: All battery chargers must be modified to work properly with true Gel Batteries. Gel Batteries prefer slightly lower voltages. If you plan to use your Inteli-Power with a Gel Battery, please contact us for details. AGM and all other types of lead acid batteries do not require this modification. Optima batteries are AGM batteries and work with these chargers with no modifications. If in doubt, please contact us for more information.

This though doesn't answer the question of can a bank consist of both flooded and AGM. The manual on my "smart" battery charger indicates the charger switches between charging modes based on battery voltage it senses. That leads me to believe that if the different batteries have different charge acceptance profiles it could lead to problems if they are mixed in the same bank being charged. Not sure if the intellipower does something like this, but I'll bet it probably does.

Check the height of the starting batteries, deep cycle are taller than starting batteries and you may have an interference.
There are agm starting batteries available now, very pricy for this application and very limited benefit IMHO.

I will check this.

Does the 9200 have a charge wizard?

House batteries and starting batteries will be different due to their use anyway. The house needs to be true deep cycle batteries and the starting batteries need to kick out lots of current fast for the starter and are not designed for a deep discharge. Go ahead and get whatever is the best battery for the house that you want.

Most RVs do NOT charge the chassis battery while plugged in. There is a device called a Trik-L-Start that installs easily that will poach a little bit of the carge when plugged in to maintain the chassis battery.

The alternator normally charges both sets of batteries. A relay kicks in when the engine is running to combine both sets of batteries.

I can see why you would want all house batteries to be the same ( and all new at the same time) but if the engine is charging from a different source why does it matter if it (they) are a different type than the house?

Now I am a little confused. I thought the Charger also maintained the Chassis Batteries?

I am very confident the Alternator charges both the chassis and the house.

I may need to talk to Jayco to get an answer to this.
