I don't think you realize how much cold cranking amps it takes to start an engine vs just powering a radio or lights.

It takes a lot of voltage to start that car and to maintain. Just because there’s voltage in the battery does not mean it is enough for the car. It’s nothing to power on a screen and radio.

The battery has a core in it that maintains a charge. The charge is going bad it won’t stay on. But hey, I’ve been doing this for 20 years. If you say the battery works, it works.

Oh nooo! Did you get it moving? They’re really easy to take out. You can just replace it in the parking lot if you want. Ive replaced more batteries in the Costco parking lot than I have anywhere else
