OK -- Now the old guy needs advice/help. The problem is up front and in my face:
Herself went to the store (5 miles away). When she came out, our 2020 Camry with <7000 miles on it was stone dead. ZERO electricity for anything at all. She got me on the phone, and Scott, who was about to leave to go back to Oregon, canceled that and we hopped in his rental.
A pretty lady in the parking lot offered her jumper cables and we got the Camry started right up. Decided to take the car (still under warranty) to Toyota. On the way, I stopped at AutoZone and had them check the battery. 12.3V <-- Fine.
At the dealership, they told me the "battery had one cell that had no fluid", and they'd fixed that. (Side note: I am an EE. That explanation made no sense.)
Now, my Beautiful Witch is afraid to go anywhere alone, and my busted bod will give me toco if I have to ride with her every day for shopping, etc.
Went back to Toyota, and told them I want to have them do the warranty 10K thing, and to pay attention to the totally electrically dead thing.
Bottom line, they came back with:
"There is a special part for the battery, and it has been on order for months. You need to hook up a trickle charger every night to the car."
For on the road fails,
"You need to have a jump-starter you can keep in the trunk."
This is, of course, totally unacceptable to Herself: I did buy ($130) a jump-starter and put it in the trunk (must be recharged in the house monthly, BTW). And a trickle-charger ($40). <-- But hooking up my car every night??
Then I did a Duck search and found this:

Here is my problem summed:
Our car is now very nearly useless. But it is needed. We live in the boonies. I checked those links, and found out about Lemon Law. <-- since the first time it went dead was NOT within the right time frame... I am screwed Lemon Law wise.
I need sooper brilliant wrenchers (eg: Boo) to tell me what to do.
