I'm using this for a rather non-conventional use as an RV charger to replace the built-in one which I burned out. I leave this on deep cycle, 2 amp trickle charge mode most of the time. Its sitting on a small stool behind some drawers in a closet. It does have free air flow. This unit is ideal for this use because unlike many automatic converters, it doesn't time out and shut off after a certain period of time, and it doesn't have a cooling fan to make unwanted noise inside my trailer. It is very quiet. If I'm running self contained and using my generator to charge up the battery through the trailer's electrical system, I will just switch it to 10 amp charge so that I can get the battery recharge more quickly and shut the generator back off. Being convection cooled, and very quiet is the perfect combination for this application. Anyone who has burned out the converter in their trailer has the choice of putting in another one (about $110-$150) or install one of these instead. I tried installing a direct replacement and had to send it back because the fan in it would not shut off, even though it was supposed to. So I thought I'm not going to waste my time with another one when I can get this for $50 and do the same thing. The trick is to get one of these chargers that doesn't have a fan, yet offers a high speed charging rate, and won't shut down automatically. This one fits the bill on all three points.

I bought this little feller to replace an 40 amp converter that expired. I use it to maintain an auxiliary battery in my camping van; the converter was overkill.

The SE is a different shape than the converter but fit. It has been doing its thing for a couple of years with no problems as has the battery. It runs 24/7 except when we are driving. In campsite, it is across the battery that the TV uses and I get no noise from it; the converter gave me a low hum.

Should have bought it the first time.

This model will not charge 6 Volt batteries, and does not have the 50 Amp boost feature, but it is ideal for all other 12V automotive battery charging duties around the shop and farm. It has circuitry for both deep cycle and for conventional/maintenance-free batteries. It can be set to charge on "manual" as well as "automatic." This is handy in the case of completely dead batteries, which sometimes cannot even begin the charging process on "automatic." The fully automatic feature allows leaving the charger connected to "maintain" a battery without overcharging.

The description says "LEDs" implying that there are more than one, but it has a single green "full charge" LED.

The most commonly replaced parts, such as diodes, switches, PC boards, etc. for this and other chargers are available from:

This is my second Schumacher charger of this design. The first one has served me well for over 20 years. Not weatherproof - use indoors or protected from rain! Under a partially closed hood works fine. You will see a review that gives this charger low marks. Please read my comments under that review.

Decent Charger, No Frills, & Basic..
I have another one from the same company and its at least 30 years old & Still works..
I Bought this when I thought Someone may have "borrowed Mine & not Returned it"
Eventually found my Original.. But, Still Glad I bought this One..
Tested & worked Great on Charging my Tractors Battery, The only thing,
I Noticed was the Charging Gauge didn't seem Right, But Eventually told me my Battery was fully Charged..
And It worked, All the functions appear to work, other than the gauge seemingly acting weird, ,but maybe
it was supposed to be that way... Anyway,, a Rugged Charger that Does its Job...

works ok. unlike some chargers, I think amperage delivery is accurate. The automatic function is somewhat troublesome as it seems to select a lower than optimal target voltage, with the result that the charger cycles on and off continuously.

The charger never shut off. The "Automatic" feature didn't work. I have another Schumacher charger, older model 10/2 amp fully automatic that works fine. Just wanted a second charger so I could charge up both of my boat batteries at the same time. Unfortunately, the one I received did
not shut off. It also got quite hot, and more bothersome, was my new deep cycle battery, was getting hot as well. I used my old charger in place and it worked fine, charged up and shut off, going into maintenance mode. This confirmed the new unit I received was defective. Made in Mexico.
But, thanks to Amazon's great customer service return policy, free shipping on the return. My refund was made right after the
returned unit was entered into UPS system. Not sure I want another one of these, maybe try another brand.

This is an easy-to-use charger. It arrived well within the stated delivery time frame and I am very pleased with it. It's not too heavy (I'm an "elderly" woman, but still want to be able to manage my automotive/household needs and this fits perfectly! It was recommended to me by a family friend and had all the features I would need. BP
