Well, shoot! And I gained a lot from all that buttered popcorn.
If they did not find a drain on the battery over 80 mA or so, then there would be no reason at all to pull any fuses.
Electrical on these newer, or any, vehicle can be a nightmare. Particularly when it is an intermittent problem, such as a bare wire shorting out just a little, sometimes, until a jar in the right direction makes it move enough it's no longer shorting.
An automotive battery at full charge will read about 12.7 volts. Some battery technology has batteries reading a little higher, maybe as high as 12.9 volts, but if the battery is newer, it should never drop below 12.6 while sitting.
At this point, if it were my vehicle, here's what I'd do.
Park the vehicle and let it sit for at least 24 hours. At that point the voltage will be at what I'll call rest. It should not drop anymore while sitting. No more than a tenth of a volt or so.
The voltage across the battery can be read without doing anything except opening the hood. There is an inexpensive volt meter at Tractor Supply of about $10 or so. Sometimes they are free.
I have one. Well actually three. But if I didn't I'd get one and read the voltage across the battery terminals at least once per day. I'd keep pencil and paper and write it down along with the date and time.
If the battery voltage was dropping from day to day, I would disconnect one terminal of the battery and continue testing. If the battery keeps going down, the battery is bad. If it stops going down, you do have a drain in a circuit somewhere (at this time). At the shop, maybe maybe not. I wasn't there. Hopefully the battery will go down when disconnected. That isolates the problem as being the problem and that's easy to fix. Buy yet another battery or return the one you bought.
But it just depends on what happens.
If neither you nor your husband are sure how to do this, get a friend that does and have them show you. It's not hard or complicated at all.
Hondo gives be his best so I owe him mine.
