Default Using battery tender thru winter

Hi all, just looking for some input. Bikes put away for the off season and generally I leave the tender on 24/7 until April. This time I’m storing 3 bikes and wondering if there is any reason I couldn’t/shouldn’t put the tenders on a timer to operate once per week for 24 hours. If it makes a diff we are below freezing here for 4ish months, although car batteries are fine sitting idle for long periods without tenders.
just curious if it’s necessary to run them 24/7 as I’ve done previously.
thanks…I hate winter!

A tender, as long as it's a name brand, is self monitoring. So a timer isn't necessary.

You say "tenders" (plural). What is the goal by putting them on a timer?

They are quality tenders and I understand they self monitor, as in charge the battery to full then ramp down to a maintenance level.
I would think in that maintenance level there is always current flowing. I guess thats’s what I question. Whether it’s of any benefit running constantly or letting it minimally discharge for 6 days and then have the tender bring it back up. Prolly overthinking it but I’m a cheap Canuck trying to save a few bucks on hydro over the winter…..

FWIW, I monitor the power consumption of my tender. It costs me 14 cents per month (@ 12 cents per kwh) to leave it connected 24/7.

Thanks for that! May have to skip a meal but that’s within a retirees budget.

All my bikes are on a Deltran's Battery Tender Plus while in the garage all year round.

yup, that’s the plan. And that’s what I’ve always done with mine. Just this time I’m plugging 3 bikes in and being a cheapass! Looks like power use is pretty minimal.

They are all plugged into a power bar that is plugged into a wi-fi timer. The plan was to set the timer to come on once a week for 24 hours rather than 24/7. I thought it might save money on unnecessary power usage….turns out that was a lie…power use apparently is not significant so plan to run it full time.
