As per a review, "it can only charge batteries up to 550 CCA". I have the same charger (bought a few months ago) and used it to charge my dead battery, which has 650 Cold Crank Amps. Once it gets to 100%, if you remove it and apply it again it will state it's at 95%.

So if your battery has more than 550 CCA, I'd find a different charger unless you needed to charge a dead battery overnight.

I prefer the past deal on the $0 Slime tire inflator instead...

where does it say up to 550 cca and how do I know how many ccas I need or if this will work for my cars? thanks!

Sears pulls this out of stock every time it goes on "sale". There were several available at my local store, now they're suddenly "out of stock" the next second after and it's no longer available for shipping. Of course, they are available again the day after the sale is over. Total BS, not really a deal if you can't actually buy the item at that price.

EDIT: Was able to get an order to go through online at ~10:30 AM CST, will wait to see if it gets shipped.

I think he's misunderstanding something. If I unplug it for a short time then plug it back in, it will read 95%, but go back to 100% quickly. This happens with either my truck or atv battery. Never seemed like a big deal to me, obviously a 95% charged battery will still start the vehicle anyway.

Anyway, I like this. Was using the HF float before, but this is nice because it provides feedback and also will charge up a partially dead battery.

That's lame. I got mine just fine last time, but it took forever, because it's one of those items that you have to pick up at the auto center, not regular pickup area.

I bought one of these right around Black Friday last year. It works great! My wife left her headlights on and her battery was deader than a door nail. 4 hours later after charging with this baby, she (the car) cranked right up. Buy this.... you won't be sorry.

Giantcrazy 02-26-2013 06:37 AM

Yeah, dead for me, OOS both online and in store (which is odd, since it previously said there were 22 in store only seconds before I clicked 'Pick Up').

Anime 02-26-2013 06:47 AM

Not really sure why Sears does this with stuff they promote as the Deal of the Day.

Maybe they think you'll buy it at full price the next day when they return the online and store inventory to normal?

Thanks for that! I was looking for a charger to keep my spare boat battery juiced up, and that'll do the trick nicely.

tstarks 02-26-2013 07:57 AM


Apparently, it's the SAME charger, just cheaper. From Amazon's reviews:


This is a great charger but the same company (schumacher's battery maintainer), makes an identical product for sears, branded as diehard.

E4300 02-26-2013 08:05 AM

550 and 650 CCA refer to the capacity of the battery. A 650 CCA battery may take longer to achieve a full charge, but this battery charge will get the job done by charging the lead acid battery up to 12.85 VDC or 100%.

I have an older 2/10/50 A charger. No problem charging a dead 650 CCA battery (7.8 VDC) to 100% (12.85 VDC) in 24 hours at the 2 A setting.

Not so sure it is.
The diehard charger reports back how full your batter is when it you start charging with it. The schumacher does not. I own both, they both work well, but I like that it reports how much is left in the battery.

I'm not sure if it will charge a totally dead battery. However, it did charge the battery that was too low to start my car because the car sat for 2 weeks.
This is a great product. I like scrolling LED messages telling you what the unit is analyzing, charging, or maintaining. It also displays the charge level in percent.

That review was dated December 17, 2007. That charger is a much older, now outdated model. The DieHard charger here is a rebadged version of this Schumacher charger [amazon.com].

Not that it won't work, and for ~$20, sure, it's probably a fine battery maintainer. But this 3A version and the newer tech is what you want if you use the DieHard Platinum or Odyssey AGM batteries and just want a basic charger on the cheap. For the extra few bucks, worth it.

If you're going to be away for six months, you're better off just disconnecting the battery cable. I would not suggest leaving this plugged in connected to your battery in the garage for 6+ months while you're gone. You might come back and find there was an electrical fire and you no longer have a car or a house.

No. The amazon linked product has no float mode, which is very important for maintaining a battery. This diehard does.

Disconnecting the battery won't cause damage, other than losing your radio station presets, clock, etc.

However, be aware that even sitting there not connected to anything, the battery will lose charge. So, you should probably charge it up completely now, and then plan on charging it up again when you come back in 6 months, before using it in the car. If someone CAN charge the battery once in a while, that'd be best, but not a necessity.

The reason for this is that lead batteries can reach a "point of no return" in terms of discharge and can build up sulfation on the plates when they get discharged too far. If it occurs, it more or less permanently reduces the capacity of the battery and hastens its death.

If you have a newer car(1990+), i would pull the battery. If you said a few weeks, this would be great. But 6 months? Seems all that electronic stuff drains your battery even when it is off. My Aztec was very bad at that. Set for 3 weeks and no battery power.

timbertop 02-26-2013 12:56 PM

I have this. For those w/vehicle in storage yes this will offset parasitic drain from vehicle's cpu, clock. Safe to use unattended, unlikely to over-charge/cause a fire. Can leave it connected months on end. Occasionally does not re-start after power interruption. Charges very low batteries but needs to see some initial voltage to start (safety feature to prevent spark at hook-up). Charges Odyssey PC680 enough to start but not all the way.

Very good, safe charger even for those who are unfamiliar w/such things. No skill or monitoring required. Highly recommend for most folks. Comes with SAE quick disconnect harness, ring terminal sub harness that can be left on vehicle, cig plug and clamp sub harnesses. Rated 2.5 amp continuous @ 12vdc. Advanced mofset circuitry- should charge on generator power where the old transformer types are useless.

Eltory 02-26-2013 12:59 PM

can you use this to charge UPS SLA batteries?

puddnhead 02-26-2013 01:00 PM

This [sears.com] like a much better buy -- currently a couple bucks more, but a better charger. Note I didn't really search all that hard, just picked another one semi-random off the Sears page. Even at full price, as it is now. Why would you buy the one in this FP deal over that?:confused::confused:

Better yet, hold out for a deal on something like this [sears.com]. I have a slightly different, older version of this, that I waited on a great deal on & paid around $30 for. Especially if you live in a cold clime, you will find the 10 & 50 amp modes useful in addition to the 2amp trickle charge mode, and the fact that the charger in the deal (per the manual) cannot top of batteries beyond 550 CCA makes it semi-useless where I live. Also, I predict that it will probably last longer if you do intend to keep it plugged in all the time, due to better heat venting.

You are starting to stretch what this thread is about....sure we can all go out and buy full size battery chargers, but the DieHard this thread is about is for something small to maintain infrequently-used batteries. Not a charger with 50A mode to start something from the dead.

I bought one of the DieHards this thread is about...coupled with a full size battery charger they make a good set....I wouldnt say buy the full size one in the small ones place. I cant hook up my 2A/10A/50A charger to my car semi-permanently and let it run while the car is un-used.

My (and your?) charger also has a 2amp mode, with a protection circuit. I guess I would ask you, why do you have two chargers, when the smaller one does nothing that the other one can?

I don't think I'm stretching it. If you really have vehicles that need long term trickle charging, then it's not unreasonable to think that you have need for faster charging, or a boost to start, so you need another charger to do that. But if you have that other charger ... what is the point of this one? Just a waste of money &space in the garage IMO.

Because the little one has quick plugs. I can wire it to my car battery, quickly plug the little one into the ring adapters and walk away while it stays charged.

My full size charger only has battery clamps. The second one you linked to is probably OK (also has the ring quick connect harness).

To me its like having a pocket size cordless drill and a 1/2" drill.

Need to hang a picture (keep an already charged battery at good level)? Use the pocket driver.

Need to drill into studs (resurrect a battery from the dead)? Use the 1/2" drill.

Wrong, I own this charger and it absolutely goes to float mode.

"6-volt and 12-volt battery charger; automatically changes from full-charge to float-mode monitoring to prevent overcharging"

And Schumacher is one of the most respected names in battery charges, I am not saying that DieHard is not, but ir will do the same job, just without the LED readings, which I am not sure are very valuable since most people will be using these for long term maintance or overnight charging.

You leave one of the wires attached to your car batter at all times? Sounds like it is time for a new battery if you need to plug it in everynight to maintain the battery.

And you can make a ring connector for any charger for less than $1.00, so that already is not an argument

I drive my car once, maybe twice a week. And even then its not very far. Plus Infiniti has "a way with batteries", OEM battery sucks. But regardless of how good it would be, Id still want a maintainer on it.

As far as the ring connectors, I was more referring to the quick disconnect capability. Sure, I can hack up a full size charger, but then Im dealing with pretty thick wires, and all I need is something to keep the battery full during non-use.

butundo 02-26-2013 02:27 PM

I do have one already and I am going to grab another. I have 3 motorcycles that I pull the batteries during the winter. These are great to use to keep the batteries fresh, but I have never used this on a car, except to see if the battery was bad. The digital readout is really nice as well.

Hmm, that is the exact one I linked to in my first post and suggested that (for some people's purposes anyway) it is a better product, so worth paying more. When I wrote that, I did not realize that it had actually been at 3/4 the price of this recently.

IME the sears deals of the day usually aren't as good as some of their "normal old deals." I'm starting to think of it as more of a marketing gimmick than true deal, and may unsubscribe from the emails if it doesn't get more appealing soon.

Me Too I am holding out...

Uh,a "maintainer" IS meant to keep your battery charged.

Finally, someone mentioned it :) For only a couple bux more (maybe even less than that with tax vs non-tax) you get what seems to be the original maintainer that everyone based theirs off of.

Going to get the Battery Tender Junior for my car, and use the DieHard model I already have for my lawn equipment and kids toys.

Actually a lot of regular automatic chargers are also not meant to charge completely dead batteries because they require at least 8 volts across the terminals or else they won't send any current into the battery. This is related to a feature that prevents sparks when connecting the cables to the terminals.

As per a review, "it can only charge batteries up to 550 CCA". I have the same charger (bought a few months ago) and used it to charge my dead battery, which has 650 Cold Crank Amps. Once it gets to 100%, if you remove it and apply it again it will state it's at 95%.

So if your battery has more than 550 CCA, I'd find a different charger unless you needed to charge a dead battery overnight.

This I don't understand because I don't think there's any way for a charger to accurately measure the amp rating, and when it comes to charging, the more important ratings are the for the energy capacity, usually stated in amp*hours (typically about 60 amp*hours) or reserve capacity (number of minutes battery can put out 25 amps and stay above a certain minimum voltage). A battery can be built a high amp rating at the expense of energy capacity, such as by increasing the surface area of the plates and using thinner plates. However for a last-ditch method of preventing battery damage, some chargers use a timer in case they can't sense full charge by voltage, which can happen if a battery cell is shorted.

Here's how much capacity no-maintenance batteries (all plates are lead-calcium) and low-maintenance batteries (at last half the plates are lead-antimony) lose in storage (also shown is how much water each type loses):

So if no-maintenance batteries retain 95% of their capacity after 180 days while low-maintenance batteries retain only 75%, why use them? Because they can withstand deep discharge better, 6 times versus 1-2 times for no-maintenance lead-calcium batteries. I can't find such information about completely sealed car batteries, like the Optimas and Diehard Platinums, which have no calcium or or antimony in their plates.

sure can! take each terminal of the battery charger and connect them to your AC adapter. Polarity doesn't matter.

Ordered yesterday.
Got an email saying "This item is out of stock and your order has been cancelled."
Website says "In Stock TODAY" (just like it did at the moment I ordered) and the price is 37.99.
Asses.
And don't give me that "oh, only *some* of them were $22.99".

Same thing

I have had some terrible luck with deals lately, this was my 3rd cancelled order this week.
