[Home Depot] Battery Tender JR, 750 ma, 12 V - $17 @ Home Depot (YMMV)

Another Home Depot yellow tag clearance deal.

Chatham store has the Battery Tender JR 12V, 750 mA battery maintainer, on sale for $17, normally $50.
Amazon and Canadian Tire have them for around $50 regular as well.

These are great for motorcycles, lawnmowers, marine batteries, atvs, even car batteries, that will be stored over time, keeps the battery charge topped up, then shuts down and periodically checks to see if a trickle charge is needed again.
A definite steal at $17, I didn't pick one up, as I am already using one of the Mastercraft Eliminator ones, but this is a smaller unit, simple plug and play. Comes with the clamps, and ring attachments. The rings are nice, as you can leave them connected at all times to your battery terminals, and during the riding season, unplug and tuck the cable away, not having to remove the rings from the battery at all.

The SKU# is 1000846237.
Here's the link it on the site: https://www.homedepot.ca/en/home/p.juni ... 46237.html

It shows $49.98 at the store near me. Great price if you can get one in your area for that.
Thanks, I never even thought to check their site, lol
It is showing $49.99 at stores near me as well and doesn't even show stock for Chatham, but I was there and they had 4 units at least.
If you get a chance, call a local store, this shows as in store only so wondering if price wouldn't be reflected because store level manager would change pricing? Not sure how accurate their system is.

FYI, I saw this in the clearance section in the tool area for $17 as well at the Oakville, Bristol Circle location. I passed as I already have an intelligent charger.

This would be fine if you have a fully charged battery that is removed from the device. If you are connecting it to a car, the drain from the keep alive would rob the charger of fully keeping the battery charged.
Not sure it would have to be removed. This will maintain a car battery. If it is in storage, or in the garage over the winter, what is going to be draining in the car? Lights are off, ACC functions are off, the only thing that would be draining, would be the memory functions of the cars computer and stereo, etc.
Deltran advises that this can be used for maintaining car battery only, not charging, but that is the main point of these units, to tend to the battery.

Not so. I have a little charger like this (different band, similar specs) and it has no trouble keeping the battery topped up in cold weather, even if I've left the dome light on.

It can charge a totally dead battery to "eh maybe it'll start" in about 4 hours. From dead to full takes 12-24 hours.

I had my charger, just like the one in the OP, hooked up to my BMW during winter storage without any issue. I've also recovered some dead power sports batteries with it, it's not the ideal but it worked.

I have one of these and a Ctek 4.3, and they are both very nice. I use the CTEK on my 72 Riviera to keep it topped up over the winter months. And the Tender Jr, I was using on my Father-in-laws civic, since he had gotten sick and barely used it. the CTEK is more advanced, and the recondition function has helped a few old batteries in it's lifetime, but price tag is a little higher also.

At $17, I'd definitely buy one, even to keep a a spare.

As you said, this will charge a battery since the 750 mA should be more than the rate the battery normally self-discharges AND the drain from a car's electrical system when off.

However, I disagree with your statement of 'From dead to full takes 12-24 hours.'. The charger will only do 0.75A per hour so for a 45 Ahr battery (which is about average), you will need over 60 hours for a dead to full situation under ideal theoretical conditions (ie. the battery accepts a charge of 0.75 A throughout the 60 hours which doesn't happen in real life as the rate of charge when getting close to full slows down by a lot).
