The indicator regarding how accurate or inaccurate now on the charge status of the battery, I can not judge. We have a 6-year-old battery and because it often shows yellow on. At the last inspection, we have also been pointed out that the battery is coming to an end. I find it totally convenient that I only the window must be shut in the garage, the indicator must be stuck to the cigarette lighter socket and into the socket with the hanging thereon charger and you're done. This is almost like the fire brigade. Since the vehicles depend on whatever power when required.
