Land Cruiser vs Camry batteries – same replacement routine? 

Got a bit of a weird situation at home – I daily drive a 2021 Camry for work commuting around Dubai, and the family weekend car is a 2018 Land Cruiser. Both are starting to crank slower in the morning heat, especially after the recent humidity. I know the battery size and specs are totally different, but I was wondering if the actual replacement process and diagnostics are similar between them. Been looking into toyota land cruiser and camry battery replacement options online and came across that Battery Zone UAE page, but what I really want to know is whether the Land Cruiser’s dual battery setup (mine has the factory auxiliary) makes it more complicated than the Camry’s straightforward swap. Has anyone here done both? I’m trying to figure out if I can just grab batteries from the same shop or if the Cruiser needs extra attention with the electrical system. Also, any tips on avoiding the dreaded radio code lockout on the Camry would be great – last time I disconnected mine, it was a headache.
