    Rated 4.4 out of 5★ by 130reviewers.
    Rated 5 out of 5★ by Great Garage Tool The Diehard fully Automaic Battery Charger exceeds my expectations and will always be a valued tool in my garage. I highly recommend it to anyone that is looking for a battery charger that is easy enough for any member of the family to use. Great tool. 05/01/2011
    Rated 2 out of 5★ by it charges but the gauge is not accurate and might it charges but the gauge is not accurate and it might overcharge.let me explain.i have a few battery's i like to keep charged.i put this on all of them,let it sit for a while and it climbed to about 67 to 69 percent.i then came back later and it said the same for hours.i unhooked a clamp and then hooked it back up and it said 95 percent full?it did this on every battery.the battery's start boiling and since this thing thinks its not charged all the way it keeps charging even when the battery's are full.basically this needs to be monitored like a manual charger.i am getting a manual one because the micro processed technology is not good enough yet.maybe in a few years they will get it down right but its not there yet. 10/12/2012
    Rated 5 out of 5★ by Great piece of equipment So far, this battery charger is one of the best that I have owned and I have had quite a few. Right away, I charged all of my boat batteries, which two were Deep Cycle and one was for the engine and it did very well. Then I charged two more Deep Cycles in my RV and the standard battery for the engine. No problems so far. I really like the carry handle and the size is about what I expected for a 20 amp charger. I have not tried the 80 amp start function, but I am sure that it works well on smaller batteries for motorcycles or maybe a half charged car battery. I highly recommend this battery charger and the price is great also. 09/29/2013
    Rated 5 out of 5★ by Best charger I have bought and you can't beat the price. It's size allows you to easily move it around and store it. I like this one a lot better than my $200 charger. I was a little unsure on its capability to jump start a vehicle but I tried it and my car started up right away. 09/02/2013
    Rated 5 out of 5★ by Great deal! This charger works great so far! I have used it on regular, deep cycle, and AGM batteries - puts them all at 100%! Nice to see the voltage level too. Like Ron Popeil says about his rotisserie, just "Set it and forget it!" Charges and maintains - and at a price well below the comparable models from the more well known competition. I checked a lot of reviews, and too many of the mainstream charger models seemed to have unexplained failures. 07/11/2011
    Rated 5 out of 5★ by Happy with the product I have not had this item very long, but have used it about five times and, although I can not yet vouch for its durability, it seems well built and works as advertised. My only complaint is the operator's manual leaves a little to be desired - specifically, I could not find what it meant when the yellow charging light was flashing and had to call customer service (which was knowledgeable and helpful). I was advised that it meant the charger was in the desulfation mode. The manual does not state this anywhere. Also, the manual states the voltage display is not available during charging and that the charger will default to BATTERY %. My charger showed a voltage reading and did not default to BATTERY % making me think I might have a defective unit. Nope, according to customer service, the manual is wrong and will be corrected. 11/28/2011
    Rated 3 out of 5★ by Good luck......you may need it. OK, yes, it does seem like a value, especially if you consider its cost per pound and what it is suppose to do. But that is just about where the good news ends for me. It is an "automatic" charger and, accordingly, you never really know what it is doing to the battery while it's "charging." Based on a hydrometer read during the charge process, the hydrometer indicated a 75% charge (and yes, it is an accurate hydrometer) however, the charger's digital read out indicated 100% charge and yet it continued to pump 10 to 20 amps into the battery seemingly indefinately (even after the hydometer indicated a 100% charge), unless, of course, the operater (you) interviens and unplugs the unit (apparently, not as automatic of a charger as it aspires to be, or maybe it's a charger on steroids, or it just can't let go because it is, after all, a Die Hard). Also, you will always know when it is charging because it has a high pitched zinging sound emitting from an internal cooling fan of some sort -- sounds like it's getting ready for take-off. Who knows, you may like it. Somebody must be buying and using this charger; however, apparently the engineer who designed it, probaly didn't. But I would give him an "A" for effort. 09/10/2013
    Rated 5 out of 5★ by Easy to use and store. Great value, 3 charging modes; Jump, Fast charge, and trickle. I have a large battery and it went from 3 volts to 12VDC at peak amps in 5 hours. I found this product to be superior to others costing more. 10/21/2011
