squonk 38,919 #27 Posted January 18, 2015 Hate to tell you this but 12.2 volts is only about 40% fully charged. 2 Share this post Link to post Share on other sites

tunahead72 2,341 #29 Posted January 18, 2015 I believe squonk is correct. I forget where I read it years ago, one of the battery or charger manufacturers, maybe Yuasa, Interstate or Battery Tender. They consider 11.4 volts completely discharged, 12.9 volts fully charged, anything in between is proportional. Your 12.2 volts is about 50% charged, maybe enough to start your tractor but not much more. 1 Share this post Link to post Share on other sites
1973Auto 80 #30 Posted January 20, 2015 (edited) Thanks all !! As long as she starts, and the Light stays bright, that is all I am hoping for. The battery is about 4 years old so she is probably about due. Thanks Again for all the help.!!! Edited January 20, 2015 by 1973Auto Share this post Link to post Share on other sites
