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

I was really looking forward to having a replacement battery charger for the 30 year old 250 amp craftsman I’ve been using to maintain a small fleet of dump trucks. Now that I only have a couple pieces of construction equipment, I wanted to upgrade to a newer charger to maintain the equipment that doesn’t run every day. I had a repair scheduled with a mechanic that needed a battery charger. Brand-new out of the box, noticed that mysterious screw and a piece of broken plastic at the bottom of the box which had no packing foam and just thin cardboard. No power to the unit. Looking closer, the mechanic and I found that it had a major crack in the top part of the control unit and had at least six wires that had been shaken loose or unplugged. This delayed my repair, cause more downtime, and had to go to a local automotive store to get a 200 amp charger. Very disappointed that this expensive unit has such poor connections and thin plastic. IMO, this unit is not suitable for mobile mechanics in and more for a white glove garage/shop. We did manage to get to turn on the unit but someone had crossed the wires and the off switch gave power to the unit! I am going to begin the return process and will include photos including the serial number in case someone is re-sold this unit. I will update my review during the process but currently Amazon is requiring that I pay for the shipping to return this item for some reason??? Cv 7/22/22 10:30am ... show more

It is good until it brakes after warranty. They don't have repair facilities and don't know who may be able to fix it. Customer support for that matter in terrible. I love the charger but pay top dollar for one year warranty and after that it brake down, just trow it in the trash. No good at all. Very disappointed. ... show more
