harrisdm says "Convienient battery maintainer" about DieHard Battery Charger/Maintainer

harrisdm — Thu, 29 Dec 2011 20:49:00 GMT

I have four different battery maintainers. I bought this unit because it was the only one that included a cigarette lighter connection plug. It allows me to quickly hookup and disconnect to an interior connection and not have to raise the hood. As for performance it works about the same as the other units I routinely use on my boat and tractor. The unknown is how long it lasts. I have used it continuously for about three weeks to maintain the battery in my 2009 chevy 1 ton truck. It frequently sits for two to three weeeks with no use. The doors or opened frequently during the non-use period which along with the vehicle computer consumes battery power without recharging....

JohnWildmann says "failed after one year of use" about DieHard Battery Charger/Maintainer

JohnWildmann — Tue, 29 Nov 2011 01:10:12 GMT

Bought two of these chagers to trickle charge two batteries over the winter. They both worked fine last winter. However, when they were hooked up this year, they both failed with the yellow light (labeled charging) blinking. I called customer service and was informed by them that this means the charger is in abort mode. This explanation conflicts with the instructions received with the charger. Evidently, customer service does not know what they are talking about. Prior reviews indicate this means the charger has failed. Took the chargers back to the store but the help was even less helpful then customer service. I intend to buy the Deltran Battery Charger which has a ten year warranty....

umichdiver says "Very unreliable" about DieHard Battery Charger/Maintainer

umichdiver — Thu, 02 Jun 2011 01:47:56 GMT

I have been using the Die Hard battery maintainers for decades and they all performed very well and lasted forever. HOWEVER, the design of the battery maintainer was changed to a switching type from a regulator type. Since then my experience with the new design has been dreadful. I purchased two of these about one year ago and both failed within six months. I attributed the failures to a nearby lightning strike and went and bought two more. Now, again about six months later, both of these are dead as doornails. I believe that there is a serious design flaw in the Die Hard maintainer and I strongly recommend against buying them. This is really too bad because the original regulator types where so good.

fixNmowers says "Great battery maintainer" about DieHard Battery Charger/Maintainer

fixNmowers — Fri, 20 May 2011 15:35:15 GMT

The Die Hard Battery Charger / maintainer is a great tool for your outdoor power equipment or boats that have a 6 VDC or 12 VDC battery. If you are storing the unit for out of season or have extended periods between operation, this is a great little charger to have. I just purchased this particular charger for my shop to maintain my battery for my electric jib crane, that runs off a regular 12 VDc heavy duty pickup truck battery. I don't have to worry about over charginr, as the little charger has over charge protection. I also use it to long charge ATV & sand buggy batteries. YOu have the option to use the 12 VDC at 2 amps or the 6 VDC at 4 amps. I like the multiple ends that come with the charger and I use the perminent eyed connectors to hook up the battery on my jib crane and I use the alligator clips to charge the ATVs or sand buggies, that I am working on.. I really like the quick connect that is inline and allows you to quickly change the ends that you need for whatever you are charging.......

TopFuel says "Keep an eye on the status lights!!!" about DieHard Battery Charger/Maintainer

TopFuel — Mon, 25 Apr 2011 17:59:12 GMT

I've had one of these devices for a year and it's been working fine. Recently I noticed a problem with my unit, which I will put in bold so others can easily find it (because it seems to be a fairly common problem)...

THE YELLOW AND GREEN LIGHTS ARE BOTH ON AT THE SAME TIME.

This indicates that the battery is completely charged (green light) but also that the charger is still in charging mode (yellow light). If this is the case, the battery will be damaged by over-charging.

Thankfully this item is covered by a 3 YEAR WARRANTY. I still had my original box and receipt, so I exchanged it for a new one and it's working normally.

So my advice to you is to monitor the lights on the front of the device and keep your receipt...just in case!

KateSmith2 says "New version not as good as the original" about DieHard Battery Charger/Maintainer

KateSmith2 — Sun, 17 Apr 2011 12:32:22 GMT

I have 6 of the older version of this Maintainer. They have worked flawlessly for years. I have had three of the current model they last one season if you are lucky.

You can tell the difference by picking them up. The original workhorse is heavy and well built. The current one is very light and made of cheaper plastic. Save your money and buy a better unit

SearsSucker21156 says "Maintainer Does Not Maintain" about DieHard Battery Charger/Maintainer

SearsSucker21156 — Wed, 13 Apr 2011 14:15:47 GMT

I purchased this battery maintainer approximately 1.5 years ago to keep a seldom used vehicle charged. I have kept it plugged into the cigarette lighter of the car all winter and the battery is dead. I will be returning this poor quality charger and buying the industry best BatteryTender. Sears just keeps sliding downhill.

bicmyster says "Had problems with DieHard Battery Charger/Maintainer, but......." about DieHard Battery Charger/Maintainer

bicmyster — Sat, 09 Apr 2011 01:35:27 GMT

Bought a Diehard Battery Charger and had problems with it. When I bought the charger, the store was out on the shelf. While looking around the tool dept, I noticed a charger on the checkout desk. I asked the sales person about the charger and they said, "it's OK, it just needs to be put back on the shelf". I said OK and bought the charger. When I got home (35 miles away), the charger would not even light up, come on, do anything what so ever. I tried with the charger connected to the battery and disconnected and either way would not work. A month later, I returned the charger and the sales person was different. They returned the charger, gave me a "NEW" one this time, made sure that the defective charger was marked (so that it would not be sold to another customer) and apologized for any problems this may have caused, I was impressed. The charger is now charging my Harley (it works!) and hopefully will be a good one.

natmmom says " The Mighty Die hard Battery Charger " about DieHard Battery Charger/Maintainer

natmmom — Tue, 22 Mar 2011 19:16:45 GMT

Living in the state of Michigan you take certain things for granted in the winter season, including snow, ice and dead car batteries.

That's why, I 'm happy to share my review with you about the Sears Die Hard Battery that sells for around thirty dollars. It'm compact in size, but powerful in operation. The small size fits nicely in my trunk. It's a life-saver for us on those freezing days when temps are around zero and my family member's cars just don't want to turn over. It's on the top of my must have for winter surrival list!

rtetu says "Ht and miss" about DieHard Battery Charger/Maintainer

rtetu — Thu, 24 Feb 2011 17:04:12 GMT

Bought five units for different uses: two for motorcycles, one for garden tractor, one for boat, one for camper battery. One unit was defective out of the box, returned easily at Sears, except that just the ferry fare was more than the cost of the unit.

Easily installed on motorcycles with teh provided pigtails: this should be an emphasized feature. I found out about these maintainer on a motorcycle user group.

So far, so pretty good.

Brn2wn says "Perfect for Motorcycles" about DieHard Battery Charger/Maintainer

Best value for keeping a motorcycle battery fresh. It was able to recharge a near dead battery in a couple of days and then automatically keeps it topped of. The direct connect fitting is great for easy on/off installation....

recieved one of these for Christmas. hooked it up to my 2007 crf250 on boxing day, charging light came on. checked it first thing dec27, the unit was dead. from reading reviews here and elsewhere, it seems that they pump these things out and hope for the best. i'd be curious to know what the sold to replaced ratio is. i'm happy for those that got one that works, wish i was one of you....

Mikek13 says "DieHard Battery Charger/Maintainer ITS AWSOME " about DieHard Battery Charger/Maintainer

Mikek13 — Mon, 27 Dec 2010 17:35:34 GMT

no more dead batteries with the DieHard Battery Charger/Maintainer just plug into an ac outlet and then connect to battery and it makes sure when you want to start that lawnmower or snowblower in the coldest of winter just turn the key and your good to GO. I liked it so much I bought 2 one for each barn to keep all my gasoline engine pieces of equiment in the BEST starting condition in the coldest day or night don't matter with the sears DieHard Battery Charger/Maintainer I like the way it charges the battery then shuts off and maintains the full charge level of the batter automatically. Well the name says it all its a Battery Charger/Maintainer and its a DieHard a name that I trust very much and of course Craftsman is another name that gurantees that it will remain in working condition or will be repaired or replaced.

LarryMars says "Would be great for a motorhome except for the odor" about DieHard Battery Charger/Maintainer

LarryMars — Thu, 23 Dec 2010 16:17:55 GMT

I bought this trickle charger for my motor home. Sometimes I don't start the engine for weeks. I liked this battery charger since I can charge the battery through the cigarette lighter and keep it inside. But it had an odor when operating (hot plastic?), so I have to plug it in outside and run the cables to the battery. I am hoping that the odor will go away after a few days. The unit is really sophisticated for $20. It charges/maintains the battery and detects and tries to correct sulfation. Wow!...
