Hi all:
I want a charger for my car that sits idle a good deal of the winter months in the garage. I believe the two top choices are the battery minder and battery tender. It seems the main difference is the desulfation mode of the battery minder. Unfortunately, Costco only sells the battery tender and I like costco and they have a fantastic return policy. Does anyone have input as to whether the desulfation is a "must have" feature?

Thanks!

No it's not a must have feature, if you keep your battery charged and it doesn't need jump starts you won't need that mode.

Have you considered buying online? Pro Logix makes some nice chargers. You could a charger capable of not only maintaining but charging a low battery in a hurry. The little maintenence chargers are designed to keep the full batteries full, not charge low batteries although in time they will bring the voltage up, but slowly.

Hi: I have a car that has not been started for about 2 months and I figured a charger with desulfation might be a good idea to reverse and possible sulfation.

Regarding the batteryminders, the desulfation feature is really nice to have (not necessarily a must have), but IMO the best feature of the batteryminders is the automatic temperature compensation. Very few chargers have this feature, and of the few that do, IMO, most don't do it quite as well at the batteryminder.

If the battery is extremely low there's no fancy charger that will fix it. Batteries that sit more than a couple days discharged are permanently damaged.

How old is the battery?

I dont know about you, but I would be buying it in order to keep it- not return it.

Check out this charger. The 10 Amp model is $60, if you step up to $70 you get the 20 amp model which is more versatile in charging larger batteries.

Better all-around, and also can act as a full-rate charger when not used as a maintainer:

Having had Motorcycles for decades, I used to use the Battery Tender chargers/maintainers. Batteries still seemed to die an early death. Close to 20 years ago I heard about the Battery Minder charger/maintainer/desulphators. The batteries I plugged into those lasted much longer. So these days all of my vehicles which can sit for extended periods, have Battery Minder's attached.

I have honestly had really good luck with the tender/trickle charger that goes on sale at Harbor Freight for $4.97

I have given many away as gifts, everyone loves them.

FYI...the Battery Tender at Costco isn't temperature compensating. That's a requirement for Colorado IMO.

The Battery Minder products are more technically advanced. I have 4 I think.

You should look for high and low temp compensation in a quality battery maintainer. The better ones from Battery Minder have it.

I recently had to replace a lawnmower U1 battery that had always been maintained on a BatteryMinder charger. The date code on the old battery was 2004. Thirteen years is a pretty good life for a battery. I'm satisfied with the BatteryMinder brand.

Most chargers that can maintain are not as good at maintaining as the quality battery maintainers.
