Our VW TDI Touareg doesn’t get driven much.
Yesterday I went out to the garage and noticed the cars dash lights blinking. Long story short Touaregs don’t like sitting around....big pain in the ass yesterday to make it happy again. I’m going to go and buy this little guy and make my life less stressfull! :cool:

Don't buy the Jr, it's for lawn mowers and stuff...

Get the next size up. Screenshot_20190108-110653.png
 
I have one of these hard-installed in each of my vehicles (including my tractor):

I have enough vehicles that inevitably they will each go long stretches without getting used. The tractor and my '83 pickup (no AC) are good examples in the summer when it's 115°F+ out.

The condensed summary of science on lead-acid batteries is that float chargers prevent sulfation of the cells. Ideally, you'd want to float them between 13.5-13.8V. A bit lower is OK, but the critical low for a car battery (i.e.: never go below) is prolonged <12.2V - that's where irreversible sulfation damage happens fast.

Also, clean your batteries before storage using a baking soda and water solution. Batteries self-discharge faster if they're goopy across the top.
 
It was recommended by a bunch of Tdi guys?

That bigger one might not fit under the hood with it closed?
How about this one?

Look at the amps, you want around the 1.25, 1.5 amps... That one would be fine.
The smaller .75 will probably work. Just just wanted to let you know that the bigger amp ones are for cars...

Looked for that one but couldn’t find it without ordering it on line.

I did go and buy this one. It’s way smaller than I thought it was going to be so that’s awesome!
