## Questions & Answers

**Q: Will the charger maintain or trickle charge a battery?**
A: The DSR139 is a manual charger and does not have a maintain or trickle charge function.

**Q: Why does the charger’s fan operate continuously/keep shutting off?**
A: The fan will operate as needed and it is normal for the fan to sometimes operate continuously. Keep the area near the charger clear of obstructions to allow the fan to operate efficiently.

**Q: How do I calculate the time needed for a full charge?**
A: To calculate the time needed for a charge, find the percentage of charge needed. Multiply the amp hour rating by the charge needed and divide by the charge rate. Then multiply the results by 1.25 to find the total time needed in hours.

**Q: Why is there is a clicking noise coming from the charger?**
A: The clicking noise indicates that the circuit breaker is cycling, the connected battery is defective, the battery clamps have shorted, the connection at the battery is reversed, or the battery is severely discharged, but otherwise in good condition.

**Q: Can I use an extension cord with this charger?**
A: The use of an extension cord is not recommended. If you must use an extension cord, make sure it has the same number of pins as those of the plug, is in good condition, and the wire size is large enough for the AC ampere rating of the charger.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best charger for battery’s
*by L***A on June 28, 2025*

Best ever for charging. Wish I had bought this sooner. I am now the neighborhood hero.

### ⭐⭐⭐⭐⭐ Worth the money
*by T***R on March 23, 2024*

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.

### ⭐ Not recommended as of now.
*by D***R on April 2, 2019*

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.
