12v Battery Charger recommendation?

I figured there was some fiddling involved . I’ll just keep using the alligator clips for now.

Currently working on 120 feet of fencing replacement, which had some interesting twists as we went along today.

Hope tomorrow’s build goes well.

 

I'm erm..., watching Netflix.

 

Tomorrow’s jack hammer day!

We tried augering through the soil today and it was just too rocky.

Only ended up striking one unmarked , active backyard water line which will have to be repaired later in the week.

But we live to fight another day.

 

Cold and rainy up here. The only project I've got on at the moment: is to convince son he wants to take the dog for the evening walk.

 

It was 66 and sunny here today.

No trouble convincing my old man or her cousin to help.

My son ended up wandering out to “help” as much as a 6 year old can.

He was more than happy to play with a spare drill though.

 

Rather than start a new thread I figured I'd just revive this one with my question. I'm looking for a maintainer for the 12v for the week that the car is turned off during the HV battery maintenance every 6 months. Is this one OK or should I pay $10-15 more for the Battery Minder?

12 Volt Deluxe Battery Maintainer and Float Charger

@Mendel Leisk has some he prefers.

 

CTEK 3.3 (cheaper, older one) or CTEK 4.3.

 

I'm only going to be using it a couple of weeks a year. I see it's a better system but with such limited use, what about the CTEK justifies the additional cost?

 

Well, I finally caved in and bought a 12v charger/maintainer. I came across the following one at a store that handles Costco closeouts and only paid $26.99 for it. That's a full $13 cheaper than it was anywhere else, including what I found online.

 

Pretty much the same here, not wanting to start another thread, so asking if anyone has used this on a Prius ......

10/2/50 Amp 12V Manual Charger With Engine Start

3 day’s sale for $29.99 (with coupon), and a Harbor Freight is a mile or two from my dad’s place. What do you guys think? I’m visiting my dad tonight so may as well get one right?

 

While I’m a Harbor Freight frequenter, I shy away from their battery chargers.

I have the BatteryMINDer 1510 and I could let you borrow it .

It desulfates the battery and keeps it well maintained. Our 2010’s original battery lasted 8.5 years utilizing this handy device.

Let me know.

 

Hi Ray, thanks for your insite and offer, I will stay away from that one in Harbor Frieght then.

I can’t or won’t borrow yours, thank you very much, as I don’t even know when I will put it on the charger. I park on the streets, so it’s either using it at my dad’s or my in laws place. But something definitely I want to have on hand once opportunities arises, as my Prius and the 12v is at 4 and a half years of age. Try to keep the 12v going for 8years just like you.

 

I won’t need ours for another couple of years.

So all it is doing is sitting on the shelf. I don’t mind it being put to use.

But if you were spending the $45 on the harbor freight charger, the BatteryMINDer 1510 is almost the same price .

That’s what I would buy if you don’t want to borrow.

 

Seems like BatteryMINDER is the way to go! I will look up Amazon for it, thank you both for the suggestions.

Actually I don’t mind paying a little more for a known brand, I’m more about better value than better price, but asked since I will be driving by a Harbor Freight Tools rolleyes:well, not necessarily going into) later today and the email advertisement got me thinking this is something I want.

 

Total piece of junk.
I have one I will give you free......if you come pick it up.

 

I bought this to maintain the charge on my riding mower for $16. It's similar to battery tender.

I installed the ring terminals on the mower permanently and just have the pigtail hanging. If you buy additional ones if you have a motorcycle or ATV. Nice thing, it comes w/ battery clamps too.

It doesn't turn on until it detects live connection and correct polarity so there's no spark when you hook them up. I've read a lot of places saying that battery maintainer should be low amp to keep the battery from overheating.
