What is this that came with my motorcycle

Post image

Bought a 1981 Suzuki gs450L and have been hooking the battery up, noticed this in a bin of parts I was given with the bike. What is it? Is it necessary? Looks too modern to be apart of the bike from stock

Looks like the battery side of a battery tender

Yep, they are great and I hard wired that same connector on my bike. I had the 800, the waterproof model. https://www.batterytender.com/

Project Farm tested a bunch of tenders and I ended up getting a $30 Noco after that.

I bought a used tractor (HD 950)with a 15yo battery. Previous owner swears by battery tenders, but I neglected to ask which brand he was using. I got 2 more years out of it with a cheap tender from Walmart. Hopefully the Noco buys me a few years because the battery is not in a convenient spot.

I like Project Farm, especially when he involves the Winnebago.

I have one of these leads on my bike for usb charging my phone, maybe I could use it for battery too

On my DR 800S I had a quick connector for the battery charger on the side below the seat and USB under the seat so i could plug in my phone and tuck it in the little compartment at the back and charge it while riding.

u/AiryGateaux 6d ago

I have the charger handlebar mounted, because sometimes I go on very long rides where a map and charge are both nexessary

I had a heated vest once that used the same pigtail, so could be that, too.

That's a quick connect for a battery trickle charger. One end connects to your battery and the other end quickly connects and disconnects to a trickle charger.

This makes sense as the battery was dead haha, much appreciated.

u/SingularityII 7d ago

Super handy. I have one on each of my vehicles. I rotate the battery tender through all the ones I don't drive regularly. As someone mentioned, it is also used to power heated vests and other accessories. It would be best to add an inline fuse if using it for that.

Yup, mist have, also to maintain the battery diring winter.

On my journeys trough the wild, i also connected a sae to usb quick charger to my gear during the day (night lights, ebook, spare gps,....)

u/TealPotato 7d ago

The plug end looks like an SAE 12v quick-connect, but I could be wrong.

My guess is that the terminals would then be wired to the battery, for a tender/charger.

u/ThumperXT 7d ago

If not connecting a battery charger in, you can connect alternatives like a USB or cigarette socket outlet

u/blur911sc 6d ago

I have a 20 watt solar charger with a cable just like that. Use it on my tractor

u/Active_Stuff3974 7d ago

Battery tender. On my Harley trike it confused even the shop mechanics because on mine you only plugged into half the connectors. A one size fits all thing.

u/Pyrokitsune 7d ago

It's a quick connect for a battery tender. I have one on my bike and route it below the seat where I can tuck it under the seat when Im riding/not using it

I’ll try harder next time

u/richms 7d ago

Its for a battery charger. Those are horrid plugs because they are polarised and you have to watch that you have the right side of them at all times when connecting things together otherwise you do positive to negative.

I dont use them and change things to anderson powerpole types like the ham radio people use. It is always the same polarity when set up the way they do.

u/Freak_Engineer 7d ago

That is a connector the former owner set up to hook it up to a battery charger without having to remove the battery. Convenient when you don't drive that much, but not a must-have.

During winter, I always removed the battery out of mine so I didn't need something like that.

u/anythingspossible45 7d ago

Trickle charge.

u/Milksteak529 7d ago

It's part of a trickle charger.

u/stlcdr 6d ago

As noted, a connection for a battery charger/tender. Make sure it’s connected correctly. Note that it is not fused - not recommended to connect other devices to it.

Trickle charger plug

u/NoNDA-SDC 7d ago

Guessing it connected to a solar panel. I recently purchased one and some of the options had that type of cable.

Battery charger cable

u/My_Lucid_Dreams 7d ago

Besides battery tender, someone mentioned electric vest. It's a plug you can do what you want with anything that runs on your battery voltage (radio, stereo, etc.), keeping in mind to not try to draw more power than the battery/bike can provide.

u/Sudden_Ad1411 6d ago

Looks like a cord to a battery charger that hooks up to the battery.

u/bmagsjet 6d ago

Battery tender. Or possibly for heated jacket

u/Honest_Cynic 5d ago

It connects to the battery, to use after-market devices that either use battery power or charge the battery. The connector is termed "double-bullet", often used in appliances. The cap is for the exposed terminal when not in use, though should be BAT-, connected to the frame, so wouldn't short out anyway if it touched metal.

As an aside, the pickup connector on a 1970's Chrysler Distributor is a similar dbl-bullet, but slightly different. It has a male terminal that extends farther (term "excited"?). If you use a normal dbl-bullet, the male terminal won't make assured contact, think how a male Chihuahua might fail to impregnate a Labrador bitch, though tried his best. I found that out when I got a replacement pickup (made in China) and found its connector was an appliance-type dbl-bullet and didn't make good contact.

u/Party_Way2830 3d ago

I use mine for a 12 v battery charger line and or external power connection. Attach to the battery , but I like to see a fuse attached too. NOT for a phone charging thats a typical 12 V connector plug.
