Is this a battery tender plug?

Title says it all. Right side of a 2003 Ducati Monster 620. Battery tender?

Looks like one to me; I've got a Battery Tender brand and mine are slightly different than that. So look at brands other than that :-)

No. Does not look like mine. Especially with that water tight seal.

It might be for a Ducati brand charger.

Yes, looks the same as the one on my 'Guzzi Stelvio.

Mine usually has a "battery tender" brand USB adapter stuffed into it but at the moment, my C-tek battery maintainer is plugged into it.

If in doubt, stick a meter in it.

It does look like a good one to me. Bet you have a powerlet socket on the left side too.

It's the same as the battery tender plug I have on my Burgman, but why not just follow the wire? It's not like there's a ton of body panels to remove to see.

It is for a tender, As it is used, Id still check where it goes just to be sure.

Every battery tender plug I've seen looks like this:

They aren't equipped with a water-tight seal like the op's picture. The battery tender plug also wouldn't fit into the op's plug.

That picture looks like a watertight accessory plug to me. It might also fit up to a proprietary charger plug.

Not saying it couldn't be used for charging, or even used with some modification with a Battery Tender (R). But I really don't think it's a battery tender/charger plug.

In reply to foxtrapper:

The battery tender plug will fit in the socket pictured in the OP. It does have the weatherproof shield but is the same plug design.
