I have quite a few different charges for the vehicles, the shop, boat and RV. I’ve been using a Schumacher SC1588 2A 6V/12V Fully Automatic Battery Charger for about 9 months and really liked the performance and dependability. Both work well for our usage, the SDC371 offers a bit more flexibility for adding Solar charging. I first had the SDC370, it’s ok but going up to the SDC371 was a better option for emergencies (40A vs 25A) charging. Overall, pleased with the quality abet the short wires, it’s workable but could use some improvement in steady flow of charging.
Schumacher SDC371
* 40A
* Use Solar Power or Vehicle Alternator to Charge Auxiliary Battery
Schumacher SDC370
* 25A
* Use Vehicle Alternator to Charge Auxiliary Battery
IP66 is a pretty high rating, totally protected agains dust and strong jets of water, makes it ideal use for outdoors.
Both chargers feature:
* Waterproof and weatherproof, the SDC370 has an IP66
* Work in extreme temperatures—up to 80° C/176° F
* Weight: 14.6 lb
* Width: 18.5”W x 7.75”D x 12.88”H
* Battery Type: Standard, AGM, Gel, Calcium, Lithium
* 12V DC-DC
Pros
* Easy to use
* LED display
* Compact
* High IP rating
Cons
* Short wires
* Charging flow is not consistent at times

Wow, I was expecting a much better product from a name like Schumacher. Especially for such a high-dollar charger. Really disappointed.
First off, the wires are permanently attached to the charger. Meaning, if you cut one too short or have to make a change later, you’ve only got about eight inches of wire to work with FOREVER. The wires are also super cheesy quality, with what feels like plastic insulation. Very stiff in moderately cold temperatures. The wire within looks like clad aluminum, so in other words, very cheap. Unless you can mount this thing within eight inches of your alternator and battery, or circuit panel, you’re going to have to extend these short wires a considerable distance.
The next annoying thing is that there’s an ignition sense wire, but it isn’t always honored by the charger. It’s supposed to be used for “smart alternators” where the charge voltage may be low, to make sure the charger is running when the alternator is. However if the charger senses a high enough input voltage, it will go into charge mode automatically. That means you can’t control the charger with a switch, relay or other signal if the voltage is high enough to cause it to decide to charge anyway. That’s annoying and unnecessarily inflexible.
Perhaps the biggest problem of all, is the idle current drain. On a battery at 12.4v, this thing pulls a solid 12-13mA constantly from the battery while in sleep mode. That is absolutely inexcusable, especially for something that is supposed to be for RVs, boats, and other things that get stored long-term. Leave this connected to your battery (without a charging source) and it will eat it alive. For this reason alone, I will not be using this device in my systems. For $325 (at the time of this writing), nobody should accept such terrible performance.
Next up, with a healthy flooded battery attached, I connected the charger’s input to a 14v supply and saw it kick into bulk charge mode and pull about 4A from the source, which is about right. Voltage across the terminals rose to over 14v and it looked pretty decent. I detached the battery mid-charge and the charger didn’t seem to notice. The charge light kept blinking, no fault light. I would have expected that to trigger some error condition or at least indicate that it’s no longer charging.
Then I reset it and attached it to an unhealthy flooded battery that sits around 9v. The charger booted up and went right to sleep (as expected). When I plugged in the 14v source, the charger woke up and went into charging mode. It started to raise the battery voltage to about 10.5v, so I thought things were good. Then, the voltage abruptly went back to resting voltage, and the charger’s LED indicated *floating* charge mode. That’s totally wrong, in that (a) it should be bulk charging the heck out of the battery in that state and (b) it wasn’t floating the battery, because the voltage was sagging down towards 9v. Still no fault LED.
Reading the sparse “manual”, I looked to the troubleshooting section, which includes a table of LEDs and their meaning. Surprisingly, the first row (which is “low input voltage” condition) says that the LED pattern is “solid alternator LED, solid battery type LED”. That’s literally the same light pattern as “everything is working fine”! The next row condition is “low auxiliary battery” which is what I was simulating. It says that should have a flashing “battery type” LED an a “solid red fault LED”. However, I got none of those. The charger just stopped charging the battery, but indicated float charging and no fault!
Needless to say, Schumacher has some work to do. I won’t be using this in any of my systems, both because I can’t trust that the charger would work if the battery is discharged past a certain point, because I couldn’t tell that it wasn’t charging from the LEDs that misrepresent the state, AND because when things were working, the idle current drain would kill my batteries and reduce my runtime.

DcTo Dc chargers have been receiving a lot of notice among Overlanders and hunters who move between backcountry campsites. The ability to have multiple charging options for auxiliary batteries and complete power stations is highly desirable, if not essential. These dc to dc chargers allow for this and automate the switching from alternator to solar and back.
I know of the alternative units, but have not had the means to compare them (at least to me, they are all rather expensive so one doesn’t purchase unneeded extra units). But I have studied them from afar, and this unit appears to acquit itself well in the paper comparison. Schumacher has an established reputation for its motor vehicle charging and similar equipment, and based on the products I have of theirs, they are well worthy of that reputation.
This dc to dc charger, when viewed in the “flesh” lives up to their reputation. Compact, but solidly built. The casing could likely be run over with a truck and survive unscathed. The connector wires arrive unterminated, as they should, this is a box you will want capable of custom installation. Nonetheless terminations, complete with heat shrink, are included. The wires are thick, 8-10 gauge by my eyeball, and appropriate to the task. Controls are few (auxiliary battery type and preference of charging source), and well sealed as is appropriate for a box which may be located in an accessible location, but outside the vehicle interior.
There’s much more to be said about installation and operation, which I will probably make available in a freestanding review, but until then I can say without reservation that this Schumacher unit is worthy of consideration and your choice.
