SAE quick disconnects

[MoPowa]

I have a couple pieces of equipment that I use infrequently or seasonally only(tractors, snowblowers...). I have installed SAE quick disconnect wire leads on most of the batteries and it allows me to quickly plug in a battery charger or maintainer. I saw on Amazon that they have a SAE plug that would attach to the outside of the vehicle similar to an electric socket in your house. I would like to buy something that lasts, buy once, cry once. Does anyone have a recommendation for the best quality manufacturer or where to get these plugs. Thanks in advance!

Good quuestion. Even the Motorola ones are made in China, but maybe to a higher standard??

I don’t think there is an automotive engineering standard for these battery tender quick connects aka SAE.

Looks like aka 2-flat trailer connector. My Schumacher battery maintainer came with one. I'd probably just source a good trailer name like Curt. I see Hopkins offers them, but they can be hit or miss. As @doitmyself suggests, I imagine only a few factories make these. They're not high-draw so little reason to get too carried away. My biggest concern would be quality plastic and is it UV-stabilized. But how to tell? I dunno

Off-road guys were sourcing forklift connectors for winches, trailer power leads and custom jumper cables. Leave one half hard-wired to your battery poking out your grille and build everything else with the mating connector.....you're ready to connect cables or a trailer winch or anything else without ever popping the hood

I've had zero issue with the SAE ones that come with BatteryMinder maintainers with the supplied rubber caps over the years.
A shot of DeOxit once and a while doesn't hurt either. And if a replacement would ever be needed they are a common item, even NAPA stocks them.

Choose the right size for the current you expect them to carry. Can't be mated with the incorrect polarity once built.

Agree. Same here. I have them, they have a small cap that covers the end too. Never an issue, and if there was, there are a million more out there.

As long as no more than 10-15A is needed, I’d be comfortable using it. I’ve seen ones fed with 10ga wire!

If I needed real power I’d look at the Andersen power pole. But given that a battery charge is not a practical continuous load at any real amount of current, the SAE works and is expedient.

I just let the pigtail stick out the grille. Nobody would know it was there if I didn’t say so.

i used an old 2 wire 120v extension cord i found in the top of my barrel of scrap wire. Almost got paid for it!

make sure it's polarized, or use an old 3 wire cord so you can't oopsie the polarities. Ask how i know.
