Keeping a Japanese car's battery alive through a Dubai summer
Toyotas here are typically high-mileage and reliable enough that servicing gets deferred; the two things that catch owners out are water pumps and the ignition coils on the 2.7 and 4.0 petrol engines. For the battery specifically: park in shade where you can, drive far enough to actually recharge rather than only starting the car, and have it load-tested before summer rather than after. A battery that reads 12.4 volts at rest can still fail its load test, and the load test is the one that predicts the morning it does not start.
