2015 CX5 doesnt have any power but battery is good
 

Hey, i need some advise here. I replaced the battery 3 days ago an today the car was dead. I checked the battery with a voltage meter and it was good but the whole car is without any electric power, none of the lights will turn on, radio, signal lights, literally nothing. I have no idea what could cause this to happen. Any ideas????

How did you test the battery? What were the results?

I tested the battery using a voltage reader and it was reading 12 - 12.2 v

Too low, a fully charged battery will be 12.7 to 12.8v

Also the battery requires a load test rather than just a simple voltage check.

Get it fully recharged, & professionally tested.

Does your vehicle have i-stop?

No, it doesnt have i stop. But i would expect that with 12v at least some lights should turn on, but the car is completely out of power, not a single light turns on not even dimmed. Its like if something is preventing power to run from the battery to the rest of the car but at the same time seems like something is still draining the battery.

Have you tried jump starting it?

Have you tried starting it by pushing the remote against/into the start button? This will eliminate a flat or low remote battery.

Have you cleaned the battery terminals?
