With all the draw on the battery our new technology inflicts on it, it behooves us to get a smart battery charger (CTEK; GENIUS etc) and plug it every 6 months, the battery's life will be doubled if not tripled and you'll get you pay-back in $ & less inconvenience.

And why is that? Yes I know some people do it with their motobikes and custom LiFePO4 batteries and smart charger will 'balance' cells inside the box and etc; why to do it with Lexus SUVs lead-acid battery? 50 years ago people didn't get dead lead-acid battery in less than 2 years!

Lexus on-board computer may show smarter error messages if battery power is not enough to start engine.
