Product Description

A Battery Charger Engine Starter That Lets You Power Up the Whole Garage

Never feel stranded with the DieHard Platinum Battery charger. Armed with unique power and safety features, this user-friendly charger assures allows you to power up a variety of batteries. Being microprocessor-controlled means this device provides fast, efficient, powerful charging and fault detection. Armed with 2 amp charge rates, you can juice up your power sports vehicles, small watercraft, snowmobiles, ATVs and lawnmowers-disappointing days at the lake and overgrown front lawns disappear (unless you get lazy, but at least it's not your battery charger's fault!). Switch to a higher amp rate with the easy push-button options and put power to your car, SUV and truck batteries. Your AAA card will surely start collecting dust when you have this charger around.

DieHard knows batteries, and the Battery Charger Engine Starter is engineered with the Custom DieHard Platinum multi-stage charging algorithm-specifically designed to charge DieHard Platinum automotive and marine AGM batteries. Since too much of a good thing can be a bad thing, the charger comes with float-mode monitoring, where a constant flow of energy keeps batteries fully charged without overcharging, so your battery stays useful even when you can't babysit your power station.

  • The DieHard Platinum Battery charger does more than just charge-it also comes with a 125 Amp Engine Start to help jump start 12V internal combustion engines.
  • This device is safe even for novices, thanks to reverse hook-up protection, which protects battery and charger against harmful effects of backwards or incorrect hookups.
  • Use the easy interface screen to accurately detect the condition of SLI engine electrical charging system alternator/generator.
  • Feel safe knowing that this product is UL LISTED, recognized for meeting the highest level of safety design standards to protect against electrical, chemical and mechanical malfunctions.
  • Choose between the 40/15 amp rates depending on size of equipment.

71227 is top of the line
I tested the 71227 charger, and like it. The meter accuracy is within 0.05 volts, and the charging algorithms appear to work quite well, although they are not described in the instructions. I observed that the voltage was generally limited to 15.5 for regular, 16.0 for deep cycle, and 14.7 for AGM batteries. The 40 amp capability is in the form of a long timed pulse of about 2 minutes followed by 15 amps for a similar time period, then repeating until the voltage has risen enough that it isn't required. The amperage isn't constant, it tapers down to limit the voltage in typical CC/CV fashion, although the algorithm appears to actually be more complex. For instance, on a particular AGM battery it went to 15.5 volts near the end of the charge (95%) with current at about 1.5 amps for about 30 minutes and then stopped (completed). I suspect that this was an automatic attempt to condition the battery. A Schumacher SC-800A charger (Schumacher actually makes the DieHard 71227 charger) did the same thing. After three discharge cycles, it stoped doing the "high-voltage treatment". Also, in AGM/DieHard Platinum mode it went to 15.5 volts briefly during one of the 40 amp cycles. Although the instructions for DieHard Platinum (Odyssey) say to choose a charger with <14.8 volts, this charger was obviously designed with these batteries in mind. The only negative I noticed was that if the AC power cycles, after 15 minutes it will come back on as a charger set for regular battery mode and set for 2 amps. I wouldn't recommend leaving an AGM battery connected on maintenance mode. Overall, it's a nice charger. I hope some of the tech info above helps.

Problems are just as these reviews describe
Bought this today from Sears. Plugged it in, said the battery was at 30%. Set for Deep Cycle / 12Amp fast charge. Charge climbed from 30% to 65% very rapidly on my deep cycle marine battery. Then it stalled at 65% and the charger cables got very hot where they connect to the battery terminals. I unplugged the charger from the wall. Then reconnected it and it showed 75%. I will be giving it one more shot, and if it produces the same results, I will be returning it to the store today and buying a different brand. Shame on me for not reading the reviews before buying this product.

Not sure if it still works?

Hi all. Bought this model back Aug 09. Only used it a few times. It seems to have an issue with charging AGM Motorcycle batteries. My Charger/Maintainer states battery is charged. This charger says its at 77%. Charges for an hour or so. Says fully charged. Unplugged. Wait a minute. Plug back in. Back to 77%. Takes another hour??? I have tested it on two AGM Motorcycle batteries. One in the bike, And a New replacement unit. Same results.

display going nuts

Worked for a year then display is going nuts, lighting up multiple displays, fan would strain. When working it worked well but the reliability is not good. Chinese Engineering. Stored indoors always.

Worked once

Junk. I bought it at Kmart, with their 90 day return policy, and did not need it until 96 days after I bought it. It did not work at all. They would not return it. Junk.

Cooked my Odyssey PC 310

I came looking for a charger for my Odyssey battery and wanted a more capable unit than the ones Odyssey sells that only work with Odyssey's dry cell chemistry. As others have pointed out Odyssey (Enersys) makes the Die Hard Platinum battery, and the algorithm that this unit uses in the platinum mode supposedly works for charging Odyssey batteries. Half true. In "Die Hard Platinum" mode, this unit defaults (and can't be changed from) a 40A rate. This rate, according to the Die Hard engineer I spoke with, will stay at 40 amps for a minimum of a half an hour! that's a BIG problem if you are using this to charge one of the smaller Odyssey powersports batteries. Odyssey says in no unclear terms that voltage should never exceed 15V when charging. otherwise the battery can be permanently damaged. This one cooked my battery by letting the voltage climb to 16V causing it to fail. The battery had to be replaced. Not too smart.

Great charger

This unit charges my batteries to a full charge in no time. It never takes more than 3 hours for a deep discharge and that is pretty good! It excells at charging the platinum series batteries do to the high rate of charge these batteries need because they are AGM batteries.

DieHard Platinum Microprocessor-controlled Battery Charger Engin

The two clamps are not made of cooper like the picture shown on the box. They are more like aluminum and would easily come off. It's very poor designed for that kind of price. Also, the fan is really loud.

Battery charger failed me when I needed it most...

One cold (around -20f), dark (six hours of daylight) morning my daughters car would turn over. She hadn't plugged in the engine heater. I thought "this will be a good test for the new battery charger I just bought" - a Sears 71227, fancy, microprocessor controlled, does it all pretty much automatically battery charger. The first problem was that the wires/cords are rated for California summers, not Alaska winters. They were all stiff as a board within 50 feet of the heated garage. They didn't want to unwind from the plastic pegs that hold them, and wanted to recoil instead of extending and clamping. Who would design something with cheap leads that very often would be called upon to work when batteries fail most - in the dead cold of winter? It failed this test miserably. If it was Fairbanks (-50f or so) I'm sure they would have shattered. The next one is reading the instructions/directions near the switches in the dark. Oh, and the handle flops just right to get in the way when it's sitting flat on its bottom. Just enough light to hook up the cables but not enough to read all the directions without a flashlight. My old, analog charger was simple - hook up the cables, plug in the cord and flip a switch. This one has three settings that need to be set up first or it's a no-go. Then the lights blink and the impression is that things are working. But 'the work' is not necessarily effective. I needed to get enough charge into it to crank the car over. The headlights were dim, but not dead, so I figured that it would only take a couple of minutes until the 'start' function could take over (125 AMPs, after all) to kick it over. My old charger (100 AMPS) would do that without problems. This one didn't. The start function lights blinked and cycled. I figured it was good to go. The engine grunted and didn't start. I let it cycle once more and didn't get any better results. I got out my jumper cables, connected them and, in less than a minute, had the car running. It took less time to jump it than to try out the new charger - but it was worth the effort to find out that it wasn't as good as the old charger or the cables.
