I recently installed the Mighty Max 26AH battery from Amazon. Fits perfect.
Also using the True Isolator. Bought the kit with the wires but not the full kit with the volt-meters. The cable I found that was too short was the ground wire since I wanted to tie it across directly from the AUX to the MAIN. I just went to walmart and bought a longer ground wire in the lawn and garden section (same guage as the kit... 6 awg). I cut it to the length I needed and put new terminators on it.
One thing to note from my experience, that the True isolator does NOT just allow one-way current. There's even a note on the instructions that the unit is "ambidextrous" so you can't hook it up backwards. I realized this when I had my battery tender hooked up the the AUX battery and after a while when the AUX battery was fully charged, the light came on meaning it was charging my main battery as well.. I was confused at first, so I looked again at the True instruction sheet and found the little "FYI" note about the two-way charging.
By no means is this a bad thing... both batteries will be isolated from each other when the voltage on either one becomes too low.
Another thing that I think is a misconception. Both batteries need not be of same type and capacity when using an isolator.
It's when you DON'T have an isolator and just simply wire 2 batteries in parallel that they need to be the same. If they are not then one will always try to draw current off the other all the time depending on type/age/size of each.

I bought but have not installed the optima deep cycle but have not installed it. I plan on putting it under the driver seat. I like exploring and have been stuck and need long winch pulls and running out of battery is very frustrating so this battery will run the winch and any lights and a radio with no problem
