12V Battery Charging/Maintaining, Apt. Dweller Solutions

My daughter in CA will be the end-user (in a couple months?) of my new ’26 LE FWD, and I’m in the process of prepping it with a few add-ons for her. One small add-on from the maintenance side I want to do is enabling ease of 12v battery charging/maintaining. A Noco Genius2 or 5 is in her future.

Like many, she’s an apartment dweller in SoCal. So periodic overnight (or longer) charging of the small 12v Yusa 345LN1 is pretty much out of the question (too far from apt. 120v/15 amp outlets to parking area). At her workplace, no outside outlets. Although she does normally drive daily it’s usually short 10-25 mi.) trips, and she has the occasional 1-2 week trip somewhere w/o using her car. So need other solutions.

I read pretty much all this thread AGM battery for Gen 4/Gen 5 Prius/Prius Prime and observations on the 12-V charging system | PriusChat. Very helpful/interesting. I have been a believer in 12v maintenance chargers for many years, then and now use them on my non-hybrid gassers with 12v battery management systems that are more convoluted that apparently what the Prius LE HEV has.

My 1st thought – I put an eyelet terminal connector under the hood at the jump start terminal locations and (somehow) bring quick-connect to outside the grill area. Every couple of weeks or so, she goes to a friend’s place, uses their (garage, other) outlet, quick-connect the Noco and overnight (~12+ hrs) or longer charge it. Likely won’t hit full charge in that limited time but seems it could help and wouldn’t hurt.

So I popped the hood, removed the “exclusive” jump start terminals cover (aka Fuse & Relay cover). My hopes were dashed when I saw the + terminal under the red plastic cover wasn’t a nut or bolt but that flat plate thing. Fine for alligator jaw terminal clamp, not so much for trying to permanently mount an eyelet connector. So she’d have to pop the hood and use the clamps for charging. So be it.

2nd thought – do the same thing as (1) at the 12v battery (hatch) end. For anyone who’s actually done this, how’d you exit the eyelet connector from the trunk to the outside?

3rd thought – permanently mount the eyelet connector to the trunk 12v battery, and use a portable power station left in the closed & locked trunk area overnight to charge the 12v. Nothing exiting the vehicle. Just remember to unplug the Noco before driving off. She has a Jackery Explorer 500. Anybody try something similar to this?

Any and all comments/ideas welcome...….
