Hi all. So, I've decided to err on the side of caution and when we leave the 300H for 32 days, I'm going to use a tender. A bunch have recommended the Genius 1 NOCO, it's inexpensive and supposed to work well. I have seen differing instructions on where to connect- to the battery, to the under hood jump points, and I'm wondering if someone would let me know where they hooked theirs and the results.
Thnx

I use trunk battery easy access

 

Do you hook both terminals direct or frame ground the (-) ?
Thanks
