Duff 206 #2 Posted January 9, 2010 If you have a float charger that shuts down automatically at full charge, I would recommend leaving it on overnight and letting it get a maximum charge.... Duff :thumbs: Share this post Link to post Share on other sites
Rideawaysenior 25 #3 Posted January 9, 2010 Im sure it can be done but at 2 amps, it's kind of hard to over charge a battery. Did you use distilled water when you filled it? Share this post Link to post Share on other sites
rocking 416 1 #4 Posted January 9, 2010 no it took a good amount of water tho I figure long slow charge will do it some good My john deere i have to charge tomarow nite and check for parasitic draw Basicly i think Re wire rather then patch Its a 1972 Share this post Link to post Share on other sites
rmaynard 16,292 #5 Posted January 9, 2010 I always leave a 10 amp automatic charger on for 12 to 24 hours to get a full charge. I have a 420 cold cranking amp battery on my horse. Battery dealer once told me that you need at least 10 amps for a minimum of 12 hours to get a full charge. That is assuming that you don't have a weak or dead cell.

rocking 416 1 #6 Posted January 9, 2010 I was under the impression Slow steady charge was best " Trickle " I charged my 416 it had 11.6v i charged it for about 5 hours 12v 2 amp She has 13.2 now. I guess its all a madder of opinion. My john deere however i may take up up on that advice. It mesured 6.2 volts on 12v battry I got it on 12 v 2amp now ill see how she is in the morning. Im not trying to be a " Know it all " just looking an listing to some new an unheard of ideas :thumbs: Share this post Link to post Share on other sites
