It is important to remember that you have the tender connected, otherwise things can get exciting when you move the car - hence the "remove before flight" streamer in the link I posted. |

Undo the bolt that goes through the battery clamp and put it through the ring terminal, then re-install to the battery. Then it's a simple plug / unplug of the included connector.

I do exactly this, put the charger lead rings along with the rest of the wiring on the battery terminals of the bikes. Do motorcycles have bodies as ground? I've always connected the negative lead to the negative terminal.

https://www.batteriesplus.com/produc...iABEgIYSfD_BwE I installed one on both the e46 cayman. Is this for the boxster? The only catch is that on the Cayman the nuts wouldn't come all the way off the bolt. The bolt seems to be modified to prevent removal. I ended up damaging the battery terminal clamp by forcing it. If the nut won't come off nicely, I'd modify the battery tender ring to make it a "C" instead of a closed ring and slide it on the side of the bolt. |

That said, there is absolutely nothing wrong with connecting directly to the battery terminals. |

I have about 10 of these things around the garage and shop. I keep one hooked up for each item that I have that (pretty much) has a battery....
The boat, lawn mower, 911, E23, E38, F250... The Mustang has a special one that is for AGM batteries... I have had great luck with them in keeping the batteries going while whatever they are attached to sits.... and sometimes sits... and sits... I have a mix of hookups: clip, hard mounted and cig lighter. Like what Terry said.. driving off with one of these hooked up would be not so good. So - for the clip and hard mounted ones - I drape the cord over the side mirror so I will see it before I drive off. Battery Tender is also ok. I have just had good luck with the BatteryMinder version.

of course I lagged getting and setting up my batter tender so the battery is dead. Anyone know if I can use the tender to charge the battery?

Yeah, you should probably just invest in a charger (or one of those jump packs). The tenders are an order of magnitude less powerful than the chargers (15 amp v. 1.25 or so).
