Ghostshad Posted September 17, 2016 Posted September 17, 2016 Will a bad marine battery give a false reading on a built in battery charger ? It says to check connection which i did & it still says check connection & never fully charges . Quote
Ski213 Posted September 17, 2016 Posted September 17, 2016 Have the battery tested. I had an MK charger that did that on one bank. It was the charger that was bad in my case. Quote
Super User fishnkamp Posted September 18, 2016 Super User Posted September 18, 2016 Yes either a battery with a bad cell can do it and so can a charger cause it. I suggest you go to your local harbor Freight ( or auto parts store, but HF is cheapest) and get yourself one of these simple battery load testers. They sell for $22 Quote
