Batteries needed

[jalichty]

I am probably reaching the end of the life of the batteries in my FW and boat. I currently have 2 size 24 dual purpose batteries in my FW and I have noticed the useful charge in them has diminished quite a bit. They are over 7 years old. Boat batteries are over 10 years old. Would love to go with lithium, but way too expensive so I'm looking at AGMs. Have been told by a dealer that my Jayco HT 26.5 RLS's convertor will handle this type of battery and I am looking mostly at full deep cycle ones. I would appreciate comments as I am not experienced with AGMs in the least.

As far as the boat, I'm thinking a dual purpose one would work great for the starting battery and perhaps just deep cycle for the electric trolling motor.

Again, any comments would be greatly appreciated.

Seven and ten years of service is excellent.

“Have been told by a dealer that my Jayco HT 26.5 RLS's convertor will handle this type of battery”

Verify this by reading the convertor’s manual and the proposed battery’s requirements.

ISTR something about boat batteries where you need certain amps draw for pounds of thrust for trolling. That determines whether a battery can do the job if it can do the amps for how long at how many amps.
The boat starting battery is no good for that apparently. Not sure if it said you can use the trolling batt for starting. Perhaps you can find info in that from Google.
EDIT
Here is that article--scroll down to where he talks about trolling motors and lbs of thrust etc.

I had real good luck with AGM. No watering, they hold a charge for a very long time when sitting, and can be mounted on their sides if need be.

Yes, they will cost you more, but like they say, you get what you pay for.
