What effect will it have if the battery is often dead?

There is no adverse effect, at most, the anti-theft fails when the power is cut off, and then the throttle user data is cleared, and the idle flow learning value is cleared. I will teach myself after the electricity is turned on. Nothing else, but in other words, your relay is only 200 amps, so it doesn't matter if you light a fire? In winter, the cold car in the northern region starts over 200A, right?
