Thanks! That never occurred to me. I use ring terminals on all mine. Old people linear thinking.

You're welcome! I need to buy a set of ring terminals, they're inexpensive. Yeah, I'm an old person too.

Anybody know how long a normal charging session for a Battery Tender Jr generally takes? Battery Tender instructions say a fully-discharged battery will take approximately 16 hours to recharge. For those of you who have used one, is this a normal number, or can it take longer?

I put the ring terminals on my Boxster battery yesterday. The tender has a single status light with four modes: Red flashing indicates a battery with too low a voltage, or ring terminals not properly connected. Solid red indicates normal connection, and battery is charging. Blinking green indicates more than 80% charged, and can be disconnected. Solid green is fully charged, and the tender has shifted to maintenance mode.

When I first connected the tender, the status light went to solid red. I expected that, and knew that things would be charging for awhile. But it's now been more than 16 hours, with no change. I don't know how to gauge whether my battery is just slow, or if there is a problem. Everything seems normal, but... ?

Yeah, yeah, I know: First-world problem.
