BatteryMINDer?

Status
Not open for further replies.
while some folks claimed good results from these, IMHO not too sure about it's effectiveness RE: de-sulphator part.

I have, over the years, owned a few of these gadgets, and I must say though I take these (esp. trickle charger grade that can only provide 1.3Amps nominal) with a healthy dosage of skepticism.

Good for trickle-charging though.

Q.
 
Hmm interesting thanks..but also looking for a charger to maintain, the de-sulphator is just a added bonus if it works...lol
 
There are some out there that have there heads in this & I am convinced this has merit.

Without pretending I have a lick of sense about this subject, I did some surfin and read briefsat various sites and the concept seems viable to me.

Simple circuitry that must be already in some modern chargers.

So you think this BatteryMINDer is a good one?
 
For that price I would go for it. I looked over the PDF & it looks like a good slow charger, regulated. As long as you can start out with a batt with 11 volts it should work out well.

I know a few with motorcycles use the BatteryMINder, although I have never had any discussion about it, they are still using them. A sign they are satisfied with them I guess.
Myself, I use a couple Deltran Battery Tender Plus, for my bikes.

I have told myself, my next will be the "Extreme Charge battery Charger/Maintainer" - just to try it out. But I'll first have to have one of my Deltran units die, or have a need for another charger/maintainer.

I know a few that went cheap and bought those Harbor Freight float chargers when on sale - and I guess they actually work too. I used them myself back when I had a boat and can't say myself that they didn't maintain the batteries during winter season. I still have them stashed in a box somewhere in the garage. It's just there are better units out there, so I may never use them again - but never know.

I guess having something is better than nothing. If it's just a float maintainer only (not charger), then the battery should have a good charge first before going float.

I understand that the sulfate buildup on the plates kills/degrades them, and these pulse maintainers are supposed to minimize from it happening.

We have several VLRA spare ups batteries at work that are on some high dollar 5-stage maintainer. Some of the older ones maybe 5 years or so pass the monthly test inspections. If I remember correctly, I think I read something about pulse technology about them. And it seems that these things were $400+ each, and there is one per battery. It's like a bunch of blinking x-mas lights in that battery storage room. That's some bucks!!!
 
Thanks for the replies guy's,another nice feature is you can hook multiple batteries up in parallel with this one to keep 2-3 etc maintained and i have a few with the OPE,snowmobiles,etc.

also has a 5 year warranty interesting..
 
I have a battery tender, a mattery minder and a schumacher trickle charger. Can't really tell if one is better than the other, or if there are long-term pros/cons. I do like to keep the battery up on my older cars that sit a long time and have lower-voltage alternators, or after a car has sat for a long time and Im going to start it up...

IIRC, in telecom and other such applications, batteries are kept at 2.25Vpc, which equals 13.5V, and telecom batteries are rated even up to 10-20 years these days.

I dont want to be boiling electrolyte or anything like this, some will as part of their charge profile... maybe it helps but I have no surity.

I have the "Extreme Charger". Seems to work OK on everything I use it on. I've built up a bit of a "Stash" of battery chargers without really knowing it over the years:

- Extreme Charger
- Princess Auto 10/2 amp fully automatic charger
- Schumacher fully auto 1.2A battery maintainer
- Deltran Battery Tender Plus (~1A I believe)
- AC Delco 2/6/10/20A fully auto charger/reconditioner
- 2 harbor frieght 1A auto battery maintainers (bought for $3.99 each).

I've soldered dual pole SAE disconnects on each of them so I can quickly plug them into my motorcycle, cars (on which I've installed the same connector for convenience) without using battery clamps. The clamps are also set up on the dual pole SAE connector so I can use it on any battery.
 
I have that one and a "Battery Tender" I got from JC Whitney. They both seem to work well. I originally got the Battery Minder because when I was running the Optima it said the voltage goes too high with a regular charger.

Never have had a chance to use the Desulphator feature.
 
Jim5 quote"- Deltran Battery Tender Plus (~1A I believe)"

I checked at their site and it's rated @ 1.25 amps - but they also say "charge as fast or faster than any 3 amp charger available" - so I don't know what's up with that.

It's temperature compensated to adjust voltage according to ambient temperature - a nice plus. It is also a 4-stage unit (Initialization, Bulk Charge, Absorption Mode, & Float).

They also have the manual (pdf.) available if you need one.

I got mine at a cycle shop sale, bought the last few they had.

Besides what came with it, I bought extra SAE connectors on the cheap. Each was double ended (SAE connector on both ends of about 6-8 inches of wire). I just snipped each, so each SAE connector has some wire to work with. A 2 fer 1 kind of package. I think they were some kind of trailer extension or something. I no longer have the packages.

isn't that an automatic feature?

No you have to watch the LEDs and if it does not charge you can attempt a Desuphation charge.
 
If you plan to charge batteries outside in the winter, then it is worth having the temperature compensation feature.

This feature is available on the Battery Tender Plus and also on a number of CTEK models. Otherwise, I'll admit to not being able to distinguish between all my chargers as far as effectiveness.

I like the Delco one the best because it has the most options as far as charge rate, displays, desulphation etc. I like the Extreme Charger for long term maintenance because (if it works as they say it does) it is always pulsing to desulfate and prevent sulphation.

I don't have the equipment however to assess whether any of them do what they say they do.
 
I usually bring them inside and trickle them for the winter so temp compensating is not a feature I'd need i would say but wouldn't mind having that feature for future use.

Whats the delco charger called?
