My battery failed on me today. Its 3 years old. I have a Power On Board Smart 25 AMP Battery Charger / 75 AMP Engine Start (B001MHW60M) from sams club that has a battery recondition cycle on it. I decided to run it. They thing has been going for about 4 hours non stop.

Does anyone know how long it takes to complete?

Also is it bad to stop the recondition cycle and just go straight over to charge?
