CTEK

Noco Genius 10. Been rocking it for years. 10 amps so you can code with it and not worry about the battery.

Currently $75 on Amazon for Cyber Monday:

I use a CTEK in the garage and a NOCO on my dual battery setup off-road rig, both have worked great.

Had a CTEK but it shit out on me so I switched it up and went NOCO Genius10 to replace it.

I have a CTEK for every car.

Anyone ever use the jump ports under the hood for the tender or should it really go directly to the battery?

Doesn’t matter.

I have an Antigravity in the M3 and I didn't realize that you can't 'maintain' lithium ion ... I definitely go a month at a time without driving it, so we're going to see this winter how good they are

You definitely can but it needs to be one specific for lithium batteries. I use this one:

I leave my antigravity on that most of the winter with no issues.

I leave my Noco on as well. On lithium mode of course.

I have the NOCO with the lithium option. Good to know, planning to buy a LIion battery next year.

Yep. Been using that on on my lithium battery every winter all winter for 11 years.

I have the antigravity charger, and they don't recommend it. They say to only maintain lead/acid batteries.

"Maintain mode - This charging type is only for Lead/Acid Batteries, mainly for capacities less than 10 Amp Hours. It charges at a lower rate of Amps and is good for long-term storage connections on smaller vehicles such as Lawn Tractors and similar vehicles."
