Brand new true start 12v aux battery One car is jumped with a battery pack it has no problem starting and continuing to run. Once you power it off it will not start back. Checked 12v battery voltage at the terminals and read 12.4v. Pulled a p2610 code with a snap on scanner I have checked for loose terminals on the battery compartment everything is tight. I’m going to try and swap in my old battery see if the problems come back. No triable or exclamations or anything out of the ordinary so far. iPhone ?
Hi... I spent the first 8 years of my life in your town of Los Altos... That is if it's the one in California. As for your error code, let's get the 12v battery issue solved first. Check all you connections, look for any signs of damage or things out of place, put a trickle charger on your 12v to give it a good charge. Then once that is done try this and let us know the results:
You might have bought a dud. 12.4 volts is not very good. Is purchase through a local dealership? I would complain, and have them test it's Cold Cranking Amps with an electronic load tester. You can DIY the test with something like Solar BA9. Nowadays nobody should be sold a battery without an electronic load test at time of purchase, it eliminates the fiinger pointing. You might also have a higher than normal phantom load drawing the battery down: have you got any accessories plugged in all the time? Maybe something's not shutting down properly? You can test for this by disconnecting the negative lead, splicing your multimeter in series. Doing that I found around 16~20 milliamps, steady, with regular spikes to around 40. The spikes may have been the little security icon blinking on the dash, not sure.
Check the battery negative terminal cable. It should be solidly bolted to the car metal. Make sure it’s snug... not on the battery side but also on the car sheet metal. Otherwise, sounds like the battery is a dud.
Yea, a fully charged battery with no load should be 13.0-13.2 volts. 12.4 is no good unless it's running the headlights.
It might be.......but it doesn't NEED to be. The nominal resting voltage for most AGM batteries is 12.8-12.9. More than that probably means that it was disconnected from a charging source in the last couple of hours......with no load.
Ahh, right... I was thinking the charge voltage. But even with the headlights on, it should be able to stay above 12 volts. If you run the headlights for a few minutes and the voltage drops below 11.5 ( and doesn't quickly come back up ) it's no bueno.
