Hey folks, I need some advice. I just changed my car battery, and the starting power seems strong. But why does it show low battery voltage as soon as I turn off the engine? Even after driving 100 kilometers, it still reports this issue. What's the reason?

My Volvo S40's battery seems fine. Why does the electrical system show a fault, and it starts smoking as soon as I start it? We've checked but can't find what's wrong.

Why does the display always show 7.0 liters per 100 kilometers, both on highways and at low speeds?

The 80th Anniversary Edition car with a 1.3T engine showing a battery voltage of 12.1V when running seems a bit low, doesn't it?

Can I use the air conditioning while charging the AION on high-voltage charging? How can I do it without damaging the battery and the small battery? Thanks!

I've checked the high and low beam lights outside the car, and they can be turned on and off normally. However, when I switch to the high beams, the dashboard keeps showing a "high beam fault," whereas there is no fault reported for the low beams. Can any experts advise on what exactly might be the problem?

Should I choose the 2024 Zeekr 009 with a 400V long-range 140kWh battery or the 800V high-voltage 108kWh battery? Any advice from fellow enthusiasts?

The car often reports that it can't detect the key as soon as I open the door... The key is a replacement. What's going on?
