Trickle battery charger

[grsthegreat]

The only harbor freight thing i own with a power cord is an air dryer. That unit is about 10 yo, and works flawlessly. But im always present when it operates.

The rest are things like hammers.

I had an apprentice that was so proud of the hole hawg knockoff he bought from HF. It melted down after the first house he drilled out. My Milwaukee hole hogs are over 25 years old and still working.

Sounds like they're trickle chargers, not maintainers, then.

No, they are float chargers, they aren't meant to charge the battery, old school trickle chargers sat up around 16 volts.

They work fine for me. I own several desulfation chargers. I have never been impressed with that mode. everytime a battery gets to the point I need to use it. I have less then a month left on it.

Ironically I just bought 2 of the 1 amp noco's above, since they are on sale.

Sorry, but I don't understand that.

I hook up my maintainers and then they remain hooked up for a few days or a year or two. If the battery is in decent shape the desulfation process generally starts within 24 hours and stays in that mode until the maintainer is disconnected.

I also have separate desulfation units (Canadus and PulseTech) that are used either with solar panels, temporarily hooked up to a battery when the vehicle will be used for a while, or permanently installed on a battery. The M6040 has had a Canadus on its battery since early '10, when it and its battery were new.

not sure what you don't understand.

FYI desulfation mode only runs periodically, it doesn't run continuously, it would overcharge the battery as it has to raise the voltage to do it. generally it jumps between float and desulfation.

I have some of my HF float chargers over 10 years running continuously.

I have two of these for each of my riding mowers. Amazon.com

Mower batteries always seem to last about one year, and the next year, start giving me issues until I replace them. I put the first Battery Tender on my zero turn 3 years ago, and so far, every time I go to start it, it fires right up. I did the same 2 years ago with my wife's riding mower.

I've been thinking about buying more for my other tractors, but so far, I usually use them enough in the winter to keep the battery charged.

Those are the ones I’ve used and had good luck with. I’ve used them on my motorcycles, lawn tractor and my current tractor the T25. No issues leaving them plugged in all off season.

And another vote for the BatteryMINDers.

Have used them for decades, and when Northern has them on sale for about $20 I often buy a couple more. Probably have at least a dozen by now.

I use battery minders. The cheaper models are sufficient, The better models have higher 8 amp charging capability and automatically go into trickle and desulfation mode as needed.
I don't often need that capability, but they sure do make excellent xmas and bday gifts.

Well, those must be different maintainers than what I've been using. Mine will turn on the desulfation once the battery is sufficiently charged, or I could turn that function on manually if so desired, and then it stays on indefinitely as indicated by lights on the maintainers.

I always thought that the desulfation process was accomplished through high frequency pulses, not extra voltage. Or at least that's what the manufacturers of various desulfation devices claim.

Also, straight desulfation units such as Canadus and PulseTech can't possibly raise the voltage in a battery since they are powered by it.

well according to this guy, it doesn't work period, even on the noco. which I can kind of relate to.

that's even more then a NOCO its only a 5a vs to 10a on the noco. And i Thought the noco was a touch pricey.
