First of all, a high quality 24V air-cooled charger like this is approx $132+ without S&H. I have Schumacher Chargers and they all operate very well for the price. The weak point on these chargers is "whimpie" wiring that is usually the cause of problems or alleged failures of the unit. If you are not "technically inclined" and have problems, ask a friend or acquaintance who can check the unit. The most common flaw, in my experience, is the connection near the alligator clips, since this area gets the most movement. A continuity check of the wiring can usually locate the fault. Also, since this unit does not have an on/off switch, I simply plug it into a power strip equipped with an on/off switch. A simple fix can save unnecessary replacement of a good unit. In my experience, Schumacher provides a cost effective product considering the price and the service.

I purchased one in February 2012 and one to replace it in August, 2012 while the other went in for warranty repair/replacement.

I bought it to charge my bank of 10 AGM batteries configured for 24 volts for my solar power system, as a back up if the batteries got too low and it was cloudy. I loaned it to a friend so he could charge his similarly configured system, and it came back dead, and the meter stuck at 3 amps. I thought he might have done something wrong but I sent it in and the manufacturer replaced it. I ordered another one in the interim.

Well, it wasn't my friend's fault. Same thing happened to me. I have the charger on a voltage-controlled outlet. When the batteries go low, my inverter is cut off and the commercial power switches on so the charger can charge the batteries to avoid a build up sulfur on the plates. One day I come home from work, and the charger was very hot, meter stuck on 3 amps, and it wasn't charging.

(Added this comment 1/9/2014) I thought the second charger was out of warranty, but I have to give the manufacturer credit: It has a 2 year warranty. I sent the second one in and they replaced it with a repaired, functional unit.

When I called Schumacher, the technician on the line told me that this battery charger wasn't designed to charge batteries that were wired in parallel. My response was that I read the owner's manual from cover to cover and there was no mention of this. He had nothing to offer in response. (End of inserted comment.)

Bottom line: It works fine for charging my boat's trolling motor batteries. However, it doesn't seem to have any protection circuitry in it, so don't use it for charging 1000 amp hour battery banks. That's not what it was designed for.

I've had the LED type chargers and you really don't know if it's working right or not. With this charger and the analog gauge, you always know what's going on.

Best 24 volt charger for trolling motor batteries . If you are looking for a charger look no further . Switches back from 12 volt to 24 volt . 2 amp trickle charges so you can leave it on all night .

It works as advertised. Would be more convenient to use if it had an ON-OFF switch. As it is, On and Off are accomplished by plugging it in and unplugging it.

I like this charger alot. I bought it as a back up to the one I bought years ago. You cann't find a 12/24 volt charger at this
price any more. It is the same brand I bought before & I never have had a minutes trouble with it. This was my 1st time ordering from
Amazon.com & it was a great experience. I got a great price on this item & the delivery was quick & I received the charger on the date
it was promised it was well packaged & in good shape.

I have only used this charger a couple of times but so far, so good. I like the fact that you can set it on automatic and forget about it. I would have given it 5 stars if there was an off switch. Would be nicer than having to unplug it, which in time will probably damage the cord. Also, after I purchased it, a mechanical engineer told me that my batteries would last longer and would both get an equal charge by charging them on the 12 volt mode sepeately rather than connecting the charger in series to both batteries and charging them on the 24 volt setting. If that is true, I didn't need a 24 volt charger because I couldn't find a 24 volt baffery, only 2 - 12 volt batteries connected in series. I still like the unit, thus far.

A friend of mine told me about this charger as I had purchased a fishing boat and it did not have an on board charger for the trolling motors. I found it to be as expected and have used it many times since purchasing. Would highly recommend for anyone looking for a charging system that they do not want to install on board.
