Odyssey Ultimizer Battery Charger

After our Odyssey battery was drained to 0 volts by a phantom load in the Jeep (now fixed), we tried charging the battery with a trickle charger. It didn’t work. The battery would charge to 10 volts and immediately lose voltage as soon as the charger was removed. The Ultimizer gave the battery a 14.7-volt bulk charge, finished the charge with the absorption phase, and made the battery perform as new again.
