How Create a Cheap DIY Quick Disconnect Fitting and Charge Two Batteries Using One Deltran Battery Charger.




Introduction: How Create a Cheap DIY Quick Disconnect Fitting and Charge Two Batteries Using One Deltran Battery Charger.

This video will show you how to charge two batteries using one deltran battery charger junior. If the two batteries are exactly the same make and model and state of discharge, you can charge two at the same time, but if they are different batteries, you can only charge one battery at a time.

And I've also shown a way to make a quick disconnect plug from common household items so that you can easily yank and go and not worry about damaging your connector on your battery tender as you throw the connector on the floor.

The battery tender connectors are made of a soft metal it seems, and if you remove and disconnect the battery as often as I do, there is the possibility of wearing it out.

Not including stuff that I have lying around this build cost only 85 cents.

The only specialized item that you might not have are the alligator clips, however, if you wanted to have alligator clips, you could buy smaller simpler ones from an electronic shop, or even simpler, just make a cheap permanent quick disconnect attachment to that battery.

    Not sure about using a 120v plug in a 12 v system. If someone who didn't know what you built this thing for plugs it in, you'll end up frying your charger.

    I built this myself and I'm the only person who knows how to use this. In my application, someone would have to get an extension cord, plug it into the wall in order to reach this plug, then plug it in.

    I'm counting on the fact that someone will not come around and think, "Gee, I wonder what this powers up? and then randomly plug it in just to see what lights up. I'd like to think that people are quite apathetic.

    In any case it wouldn't fry the charger. It's fused and protected, and the only danger is frying the other battery, but since both batteries are on disconnect switches, the danger of frying the other battery is quite small, unless both batteries are being charged at the same time.

    Still if you are really concerned, you could always add a fuse to each battery, but that would add to the cost. Simplicity and cost were the two main concerns here, and now that everything is installed, getting the battery plugged in is really easy, and even better, when going out, I just yank out the plug hard, drop and go.

    The second video will follow in a bit. Thanks for the comment though.
