Bringing an AGM Battery back to life


Recommended Posts

Posted

As the title says, My Yukon has been in the garage for about a month. I went to start it and it would't start. I charged it for approx 24 hours and the charger said 100% but @ 6 volts (it won't go any higher than 6 volts). What can I do or is this battery trash?

Battery is an Odyssey 34/78 AGM, charger is AGM compatible W/ 3amp & 15amp charging capabilities.

The voltage is too low for the charger to turn on. Trick it by wiring another battery in parallel, and then start the charge. Charge at the lowest possible setting.

Thank you _Paralyzed_, I found an article and video on this and I'm going to try this when I get home. Also known as Boost Charging
