    • Finally!
Style: Charger
Had this for awhile now. Former GM service tech familar with the midtronics GR-8 battery/charging systems diagnostic station. The GR-8 is a 60amp charger along with a bunch of other stuff. This is 50 amps and doesnt care about safety this and that. You turn that knob and amps are going to come out of those clamps and alot of them. Dim your shop lights amount of amps. Reccomend having on a 20 amp breaker. Havent used it heavily but man is it nice being able to charge customers dead batteries in about 2 hours instead of overnight with every other charger ever. Can even use it to function test starters if you know what your doing. Just dont use any more then the 10 amp setting. On 10 amps while connected to a starter on the bench the amps guage needle buries itself beyond 60 amps. Can also use it to maintain *close-ish* to charging voltage with ignition on engine off for testing purposes. The clamps are decent quality and the function knob has a heavy snap action to it. On/off/timer knob feels quality too. It says on the back there is a max 10amp continous 12v charge but when i put it on 50amps it seems to stay on 50 amps but i havent tested on a flat battery yet. ... show more

    • Worth the money
Style: Charger
It does what it is supposed to. It is easy to assembly and easy to use. As stated in other reviews, the ammeter is inop (does not work). Not a big deal to me, but it does that mean that the manufacturer is using lowest bidder suppliers for part? Time will tell. In the meantime it is working just fine in my shop. UPDATE: I am changing my rating from 4 to 5. The ammeter actually does work - once the battery starts to take a charge. ... show more

    • BACK TO BASICS, NO COMPUTER A+++++
Style: Charger
I love this charger because it is NOT a smart charger. There is nothing more aggravating than a dead battery and a charger that wont charge because it thinks its smarter than you. You can't fix stupid but you can now buy a battery charger that is smarter than their computer run smart charger. You don't need a computer. You need a simple back to basics no frills battery charger that charges and jumps a battery when you need it. ... show more

    • Not recommended as of now.
Style: DSR124
The media could not be loaded. Schumacher customer service is great, once they realize you actually know what you're talking about. My units flash programming mode didn't work out of the box but they got me taken care of. Overall it's a great charger, the desulfate mode works and brought back an AGM battery that was over 10 years old. Update: The flash programming mode works, however the current output is slow to respond and not stable at all. Like if you suddenly remove a load the voltage jumps a substantial amount, if you add a load it drops and is super slow to respond. I've made a video and started an exchange hoping this unit is just defective. I will update my review when I have the replacement unit to compare how they behave. If the replacement unit has the same voltage regulation problem, this will be a huge issue since I've gotten the voltage to jump up above 19 volts while connected to a good fully charged battery! During flash programming you frequently cycle the ignition and fans and lights and other loads can cycle. Just imagine if it dips the voltage as a pcm is initializing, it could brick it. I emailed Schumacher but have not received a response after a few days so I decided to post this review and take them out of the loop. Update #2: The replacement unit arrived which I immediately tested, sure enough it also has voltage swings although not as bad as the first unit. As of right now I am going to recommend avoiding the unit and purchasing something else, a shame really. The unit needs to respond faster to voltage changes, I worry that vehicles that monitor voltage during flashing like BMW might kick you out of the flash due to how long it takes to recover from a voltage drop. I also dislike the fact it has no current display when in flash mode, you have no idea how many amps you're pulling from the unit. I expect more from the DSR series, especially considering the cost of this unit. ... show more

    • Exactly what I wanted, a manual charger without all the safety nannies.
Style: Charger
This was exactly what I was looking for, a manual charger that can handle dead batteries and different styles the automatic chargers fail at. Most of my automatic chargers wont touch a dead battery. They'll all state failure, or refuse to charge at all. Hook this charger up, select the amperage and turn the timer and it will charge no matter if the battery is flat dead or partially charged. I'm used to the old school chargers you could arc weld with - Not these new electronic chargers that refuse to charge anything. If you are looking for a good charger, this is it! Keep in mind, I got 2 and both were damaged on delivery. One thing it looks like is they don't handle these carefully - So don't be surprised if the outer case is dented or damaged. Mine was twice, however I just accepted an adjustment (refund) and kept it because the damage didn't affect the operation. ... show more

    • Highly recommend
Style: Charger
This product is a great way to extend your battery life. I have used this to charge batteries that have been sitting without use for several weeks. I've also had to use this when the alternator in my vehicle quit working and the battery drained. I love the timer. The construction is superb. I like to drag it on its wheels to the vehicle. The versatility to be used with different types of batteries, as well as different charging needs. ... show more
