There's no such thing as a "deep charge".<br /><br />You should use the 2 amp setting for at least 6 hours if it's completely dead...then you can switch to 6 amps if you want.Originally posted by Nate in AR:<br />Car batteries dont need a deep charge.
No battery NEEDS a slow charge, ALL batteries will benefit from it. Cars don't NORMALLY cycle the battery at all; however, Heinz has. In doing so it has created more sulfation than would happen on a deep cycle battery. A slow charge is better at removing the sulfation. The thickness of the plates has nothing to do with how long it takes to charge, amp hours are amp hours. If you are not in a hurry a slow charge is best for every type of battery.Originally posted by Nate in AR:<br /> Should have been more clear. Car batteries do not need a Deep Charge (as in like a slow charge like you would do a trolling motor battery)<br /><br />Cars dont need it because they do not cycle low enough to create much sulfide(sp?)on the plates. They also have thinner plates than a deep cycle battery therefore do not take as long to charge as a deep cycle battery.
Dang ZMOZ, you are darn near as smart as I am on some things. Good solid advice.Originally posted by ZmOz:<br /> <br /><br />No battery NEEDS a slow charge, ALL batteries will benefit from it.
