People here act like gas cars don’t have batteries. lol. Idiots. Why in Florida do I have to change out my gas only BATTERY every couple years? People don’t think.
Not lithium ion batteries. This battery is for running an electric starter primarily, is portable, and does not cost anywhere near the worth of the entire car.
And the engine is used to turn an alternator to charge that battery.
If you need to change batteries even as frequently as that, then you need to avoid cheap batteries.
