Battery Charger Testing Results
- Thread starter JHZR2
- Start date
Gotta love spellcheck and not having your readers on when typing lol. Moto power 1000ma. Looks like a neat little experiment.
The moto power arrived today about noon and it charged up the daily for about an hour. I just checked the resting voltage after burning off the surface charge and it showed 12.64. If this thing doesn’t fry my electronics or short out and burn the place down then it’s a winner.

I’ve used the motopower the last few days and nothing eventful to report. Once it’s full charged the battery, it supplies a consistent 13.4 volts continuously…..no more no less. I don’t know if that’s bad or good? I also am leery of this being good to use in an agm, even though it states as much. No adjustment, just plug it in and it does its thing.

Compared to my battery minders, that is a little low for cold weather on an AGM. That would be about right at 77F. I see around 13.7 when it is in the upper 30s in my garage.
That may very well be the tester I used on it. It states that it supplies 13.6.
So these motopowers are decent but if you lose power they won’t reset which means daily checks.
I’ve got an axtra that resets and has settings to charge in cold weather making it ideal when we spend our winters in Florida and Ohio in the summer starting next year. I’m also interested in the cheap, 1 amp battery minder but it doesn’t appear to have any sort of memory?
All in all, I spent less than $30 for a pair of these cheap motopower chargers and don’t feel like I overpaid. Using a different tester, they do float at 13.6 and the algorithm is very consistent. I’m positive they aren’t something I’d hook to a boat or anything in storage and expect it to work all winter unattended. But still a great value and performs as advertised.

I just got the pro logix pl2140 and am going to leave it hooked up this week while I’m away on business. I put it to work last night on my 24 with an agm and it’s a goofy charger. It instantly went to stage 4/completion and then stayed there all night? It never finished the charge, which I don’t understand. It’s now hooked to the car that’s going to sit all week and has actually gone through the proper sequence and I’m waiting to see if it will actually go into maintenance mode. The instructions in the owner’s manual are way more complicated than they need to be. I will say the power cord is of very high quality while the alligator clips are downright pathetically small. Why can’t companies copy the Noco clips.
I’ve bought a couple of those motopowers for friends. Small, simple to use. Have not had one fail. For things like protecting a riding mower through the winter, they are my goto easy money recommendation.

Which "it" are you speaking of?
I can verify from personal experience that Battery Minder brand does. And Granite Digital "save a battery" does not appear to.
Many on this forum claim they have successfully desulfated with Pulse Tech.
So Pulse Tech and Battery Minder clearly work.
How about Ctek? They say they do. Any experience to the contrary?

Never able to determine, it broke before I used it extensively. Perhaps someone else can chime in.
I can attest that my Black and Decker 15 amp charger with the "Battery Recond" setting does NOT reduce the internal resistance of any of the old or neglected batteries that I've tried it on.
Ctek, Battery Minder, Battery Tender, Noco, Schumacker?
I have Battery Minder 1510 and it helps a battery to keep on "cranking" but it does not restore CCAs or internal resistance and similar experience with Ctek. I left a battery plugged in to these units for about a month, per suggestion from a Battery Minder rep.
Which Battery Minder do you have and what improvements did you notice?

Look at that, Amazing !!! You have the magic touch and I mean it. I so many "chargers/desulfators" and nothing. Now, I am curious if Battery Minder 2012 is somehow different/better than 1510. You have done very detailed tests.
Could the results be because you started with Battery Minder BatteryMinder 12117 and you combined it with XC400? I saw you mentioned that 12117 kept the higher float charge and I agree, it is not a good idea to leave it.
Also, I noticed you periodically monitored water level. Is your battery the type that allows you to open the vents? I have a regular, sealed battery and don't think it is possible to somehow open the vents.
I had my old 2019 Subaru Impreza battery sitting on my garage floor. Battery is bad. Should be 500 or 550cca. It is showing maybe 375 and the resistance I think is over 6 but might be higher. I used 2 different CTEK chargers on it and it doesn't seem to be making it better. I have an old Schumacker maintainer that is 2 amps. For gits and shiggles, I just hooked it up to see if it does any better. Supposedly, it will also desulfate.
I had this same charger hooked up to my old H6 Interstate in my Audi which did ok for a few years but then died late last year (never drive the car except to pull out of the garage to get or put back xmas tree and window ACs). That battery was from 2015 and I stopped driving the car in 2020. It did die a few times and required a jump but it still functioned for a few years before taking a dump.
