I think my battery finally died in my 2016 Promaster 2500. Seems letting my van sit for 3 weeks without starting it might have killed my battery. I do have it connected to a DC to DC converter but when the ignition is off it the DC to DC charger turns off. I'm guessing the battery slowly drains regardless. I connected a Noco battery charger to it and it shows the voltage at or less than 25% and after an hour shows the battery at 100% but if I disconnect and reconnect within seconds, the battery is back at 25%.
Hi, do you need to plug the vent tube back in?
What was the battery size. Could you get a AGM Replacement. Did you reconnect the breather vent hose?? Thanks
Thank you!
thanks!
