Awesome charger in small compact form

I remember when battery chargers used to be the size of car batteries, so I was a little skeptical when I seen the size of this charger. It's about the size of a check book, or more precisely, the size of the box your refill checks come in. This charger is totally automatic. All you need to do is attached the positive and negative wires to your battery (after plugging the charger to a wall socket or extension cord) and the unit will do the rest. The first thing it does is analyze your battery to make sure that it is "good". If the battery is good, it goes right into charging the battery and it will display in percentage what state your battery was in. For example, both my car and motorcycle batteries were dead. I picked up the charger in the morning and attached it to the car battery around 11:30am. The indicator stated the battery was good and was at 97%. I checked the battery throughout the day and evening and around 11pm, I noticed it was now in "maintenance" mode (i.e. trickle charging). I went ahead and disconnected the charger from the car and placed it on the motorcycle battery. The motorcycle battery was also good and at 37%. By 6:30am, the charging was complete and was in maintenance/trickle mode, so I disconnected the charger and unplugged it from the extension cord. The instruction book doesn't state what the percentages mean, but I gather that the car battery at 97% meant that it was "almost" completely dead. The car wouldn't crank at all, but on the motorcycle, with 37%, it tried to turn over but ultimately the battery just didn't have a strong enough charge. The charger comes with 3 types of connectors, with quick release connectors. I just used the standard gator clips as shown in the picture as those are easier to connect to the battery terminals. I tell you, this was a great purchase. I have 3 cars and 1 motorcycle, so at times one of these vehicle will sit for quite some time and usually the battery will be dead. The car I spoke of earlier only sat for less than 2 weeks before the battery died. This was a brand new battery i got from Sears back in November, so I know it's not a bad battery. I must have some sort of accessory that is slowly draining the power. I'm not sure what it could be though. I have these aftermarket illuminated gauges for my dash board that needs to be manually turned off and I've left them on accidentally for 2 days and never had a dead batter. I know I didn't leave them on the last time it sat for two weeks so I need to check for something else, but at least I have this battery charger now. Only bad thing about this charger is that the cord is really short. After getting a just start to move my car, I had to park really close to the garage door so that cord (attached to the extension cord) would fit beyond the garage door. I mean, it wouldn't make much sense if someone came along and could unplug my charger from the cord, but at least with the connector beyond my closed garage door, it would make it more difficult to unplug.

Great little maintainer!

I have three of these and they work great at keeping your batteries up to snuff. Also important in a cold climate is keeping the batteries from freezing, which is another reason to get a batter tender like this. Make sure you check yours when you get it home to make sure it works - I got one dud out my three, but it was exchanged happily for a working unit.

Awesome Sauce

So I bought this because my battery decides to Die on my Truck every other week if I don't drive it. I have a HUGE battery let me add 1079 CA and 875 CCA . so after the reviews I did not think it would charge my battery all the way. When I got it I read the instructions right away. It said there are a few different modes and after reading about them. I see why people love this so much. I hooked it up and my battery was only 25 percent charge. It took about 8 hours or so give or take. It was at 95 percent and I had to go so I put it in the truck. And it sounded like the first day I got it. I did not even get into Maintain mode which helps fix cells and such. I own a Motor Craft Battery. OEM for my Truck. And this is a must have if you have a small Draw and cant find it or just having battery issues. Keep your batteries going. I did get it on Sale, but even at 45 dollars its a steel for the Technology.

Excellent Charger!

This is a great cheap charger/maintainer! I have a 98 jeep zj 5.9 that stays parked in my garage the majority of its time. The battery is often low from sitting and me opening and closing the doors so much. Ive installed this charger with the ring terminals so that i can quickly hook it up and lower the hood back while it maintains the battery. This charger comes with regular alligator clips, ring terminals, and a cig lighter adaptor. The ring terminals have a weather proof cap that goes over the plug for when its not in use. I bought two of these on dod for $50 shipped. One odd thing ive noticed is once it goes into maintain mode, if you unplug it and plug it back in, it will say 90% or so charged and start charging again. Otherwise, its a nice little charger.

Works great

I purchased this when it was on sale. I leave this connected to my car that sits in storage for most of the year. The maintainer works perfectly and as expected.

Good for maintaining

I tried to charge my car battery, but it will take a long time I guess. It does the maintaining job as indicated on the manual. So far so good, but I will keep using it and update the review.

Very Nice and Small LED Charger

I purchased this during the Xmas sales and have already used it to recharge two very dead batteries. It is well worth the money.

Seems to work

Hello. I bought this to replaces a Black & Decker 1.2A unit(BM3B). Purchased over a year ago. For my 2010 Yamaha Majesty (YP400). Never had any issues with starting using the B&D. Saw the Diehard on sale. Decided to give it a try. Soon as I plugged it in, The Unit stated my Battery was only at 95%. About 25 minutes later switched from charging to Maintainer. The bike seems to start stronger. Maybe its just me. I do use this "Scooter" as much as possible. Even in 30F weather. Rode in rain on several occasions. I have only used it for about a week. So far so good. Years ago I did try a Schumacher 3A charger/Maintainer on a Honda SilverWing. Battery died 2 weeks later. Bought that bike used. Who knows?? The replacement battery failed too after a week. Dealer blamed the charger. ???? I'll Update if allowed any issues.

Easiest charger to use.

I have to regularly charge a motorcycle, two tractor batteries and three jet ski batteries. I hooked up to each battery and it reads the voltage, displays the current charge percentage and then proceeds to charge to 100%. It charges faster then I thought it would. I was never sure whether my batteries were charged or not on my old charger. I bought a second one for my son to use on his tractor battery. Excellent deal!

Great little charger

Got it and hooked it up to an Optima Redtop that I felt was basically fully charged. It spent maybe a half hour charging it and then went into maintenance mode. I noticed that the next time I started the car it seemed to start a little easier then the last few times (it's a project, so it doesn't get run for very long). I then hooked it to a motorcycle battery of unknown charging and it charged it right up. Lastly, I hooked it to a motorcycle battery that was suspected dead. It tried for a little while then noted that the battery was faulty and it shut down. Great little charger and I really like the LED display.

Very Nice Float Charger

I picked up two of these during the last sale, they came and I`m only sorry that I didn`t get two more. A very nice float charger for the money.

Way better than the $60 battery tender for boat

I own three of these for my boat, ATV and tractor batteries. When my other chargers would not charge, these somehow reconditioned the battery as a trickle charger. Using same boat batteries now 6 years old. Amazing! Best charger made to date!

Great Charger

I've used this charger on older batteries, new batteries for trucks, cars, ATVs, and boats. Outstanding performance every time. The analysis and % charged function on the display are very helpful. Overall design is good and it's lightweight. Hanging hook great for under the hood or tight area with no shelf space. I also like the ability to use different connectors via quick connect option.

Great Charger and Maintainer!

This is my second Platinum charger which I use to maintain the batteries of the two cars I store for the winter months. I like the digital readout and the great job they do keeping the batteries charged.

Best inexpensive maintainer

Now do not expect to charge a large discharged battery with this charger as it is not designed to do so. It will charge small batteries and maintain large ones. I have had several of these maintainers (including the battery tender, Vector, Bl & Decker) to keep auto and deep cycle batteries maintained. I believe this one to be the best of them. It keeps them maintained with no signs of overcharging. I have left this charger on my deep cycle batteries all winter without a problem. They need to be fully charged and it will maintain them. They are large 150 ah batteries. It can charge smaller riding mower batteries and smaller car batteries if you are not in a hurry. It will put out max charge for 12 hours then abort charge. It is rated 3 amp for 1 hour and 2.5 amp continuous as stated on back of charger. It has a plastic case and does get fairly warm when charging a battery. No more so than other chargers. I like the display that gives % charge or if its in maintain mode or error messages such as bad connection or abort charge. It has desulfate mode but I cannot comment on its effectiveness. 3 year warranty from Sears. It comes with 3 sets of connectors. I got them on sale for $18 and am very pleased with them. They have outlasted and work better than the other maintainers I have used.

Excellent Buy

An automatic charger. This charger recognizes the batteries you are charging. If you charge a battery that is not compatible to it. It'll show you a charging error. This kind of worning was more than I expected for that price.
