We've never had a battery last more than 3 years in the high desert. Heat kills....but it can get below freezing at times too. When fully charged, car batts should be 12.6 volts. If you're at 12 volts even, start looking at electrolyte levels or a new one. Glad your issue was just the batt.

I have a problem in my rx350 2011 model. I drove it for about 6hours journey a day before it developed this problem. It was fine and had no problem whatsoever, I then pop to the shop to get water and returning to the car to leave, it won't start. Everything works well, it crank as if it's gonna start but never start up. A suppose profession came to have a look and he is not even sure what the probs is, he is suggesting is the brainbox that is faulty but still not 100peecent sure haha. I can for holiday to my home country in Africa and am not surprise the electrician can't diagnose it. Can anyone help with suggestion please before they start guessing solutions with the car. Thank you

Disconnect both terminals, measure and record voltage with nothing connected. Clean posts and clamps. Verify polarity, reconnect. Measure voltage. Should be 12v or slightly more. Turn ingestion ON and measure voltage again [should be the same]. Apply brakes and confirm the brake lights light up.
If by chance the battery terminals were reversed, check fuses in the engine compartment fuse box.
