I'm trying to replace the battery on my modified 2016 Toyota FJ Cruiser which has a dual-battery setup for my fridge and auxiliary lights, and most shops I've called either don't understand what "group size 34R with reverse terminals" means or just try to sell me whatever they have in stock. I need someone who can actually look up the correct cold cranking amps and reserve capacity for my specific setup, not just hand me a battery that sort of fits. A fellow off-road guy told me to find a Dubai Professional Amaron Battery Dealer that works with overlanders and understands the difference between starting batteries and deep cycles. Does anyone have a recommendation for a shop where the staff actually knows their product line beyond just reading a catalog? I'm willing to pay a bit more for proper advice that keeps my fridge running overnight without killing my starter battery. Really appreciate any leads from people who run dual-battery setups here.
