My timers are not that smart ... I can turn it on / off for certain hours every day but I can't schedule it to turn on /off for specific days in a week.
CanTire has some good, cheap NOMA ones you can usually get on sale that are really great for this. Set the day of the week, or just weekdays, or every day, etc. All digital. I used them on my freshwater fish tanks setup when I had it going in a big way :)

Humans forget stuff easily.. Like batteries you aren't using, or lights for fish and the planted aquarium...
A timer makes it easy.

which one are you referring to? Battery tender Jr?

I use the Junior for my motorcycle over the winter, but right now it's plugged into my wife's HRV since we haven't been driving it during the pandemic. Keeps the battery topped up (but not sure if it would be able to charge from empty though)

But if you disconnect the battery terminals while the tender is connected, in theory, it should increase its power and maintain at least the computer settings? And presumably, if this is do-able without getting electrocuted.

Maybe you like single purpose devices, I don’t. Why not expand your thinking a little?

that’s brilliant! I’ll make sure that every time a battery in my house dies it’s only in the summer. Got it!!

Never understood why something so dead simple is so overpriced.

When my NOCO genius died, I got a 2A Motopower smart charger for $26 shipped from AliExpress (sale+coupon)--well reviewed on AliExpress and Amazon. I am super happy I didn't go with an overpriced charger again. As an added bonus, opening up the Motopower shows that it uses nice big through-hole components, which are both robust and if something does blow on me it'll cost pennies to replace.

Use some of the money you save to pick up extra quick connectors for all your vehicles, super long cables, etc.--things that make the tender convenient to use. Guess what? If you actually use use your tender properly, you won't ever need the recovery/reconditioning/desulfator modes (which mostly don't work anyway). Plus not having those high power modes makes the device safer.

Is the suggestion above of disconnecting the battery for the winter the best way to keep the integrity of the battery? Eventually recharge before reconnecting. The car is not full of electronics.

So would something like the NOCO Genius 2 or 5 work to deal with a vampire draw we have on a 2004 Honda Accord V6 EX that is running down the battery after 3 to 5 days parked?

This is a vehicle brought into Canada from the USA by a relative and had to have work done on it at Canadian Tire to bring it up to safety standards such as adding daytime running lights. I believe since CT did the work the issue started or was made worse. We had a BCAA auto tech here once to start the car and he was disgusted by what he saw of how CT hooked up the running lights. I've been pondering if there is a very low draw going across the headlight bulbs heating them up but not enough to glow visibly to the human eye.

Looking for a easy remedy as the car is off the road between COVID and the $5000 a year ICBC wants for insurance for the 19 year old that wants to drive it. It is parked a foot from our garage door in the driveway so should be easy to run an extension cord to the car if we can hook in something like those terminal leads shown in the video earlier.

At 12V, I doubt you would be electrocuted.

But to the point, if you disconnect the battery, that tender would probably detect the disconnect and cut off the power.

Yes and no. Lead-acid batteries like to be fully charged all of the time so if you charge the battery fully when you disconnect it and charge it once every month to a month and half during Winter, you'll be fine as the extra charging will slow additional deterioration of the battery. The key is to keep the battery full when possible.

It depends...

Did you charge the battery fully prior to leaving it parked 3 to 5 days? - ie how full was the battery when you parked the car?

I do not know how full it was when we first parked the car. The battery is less than 2 years old but the car was problematic when we took possession a few months ago. It has drained dead several times since and I suspect we'll be buying a new battery in order to start it up at least once every couple of weeks.

It is what comes after buying the new battery that I'm worried about.
