Schumacher Electric 6 Volt / 12 Volt Battery Charger for Ride on Toys - Charge 'N Ride CR6-3 Amp, Fully Automatic 6V / 12V Battery Charger - Charge A 3 or 4 Wheeled Toy Car Battery 3X Faster

I really like this charger over the original charger.

Battery holds a good charge.

Came as advertised. The amazing thing was that I ordered it thursday near noon. It arrived at monday lunch! From the US to Sweden that is. How is that possible? 😂 Granted, I paid for fast shipping but this is insanely fast.

Overall this appears to be a decent little charger/maintainer, and can be used for other batteries as well, with a set of alligator clamps. I have an older Schumacher 1.5A maintainer that I've used for the same purpose, but the new design doesn't use the large transformer from the mains voltage anymore, which makes it about half the weight. This new one isn't twice as fast as the 1.5A, as I would have expected (not including the float stage, that is independent of the charger) The current clamp shows ~2.05-2.1 amps DC for a 12V SLA battery at ~12.5-13.5v. I assume the internals of this unit are the same as the 2A battery maintainer Schumacher also sells. Maybe is is 3A peak? Not sure, I'd need to hook up the o-scope. The circuitry is decent, they use a rectified high voltage stage to pulse current into the battery, so the averaged current comes out to 2A. The pulsed voltage is about twice the battery voltage, RMS, but this will depend on the battery as well. I do like how they integrated an output relay, which is important as the output voltage could get quite high if something went wrong, so plus a star for that. They also used a thermistor on the heat sink for the output diode, which should tell the IC to shut the unit down if it overheated. The case isn't vented, which is good for dust intrusion, but bad for heat dissipation. The diode runs about 110F under full load in open air. It will likely run a lot hotter when encased. Not sure why so much heat is generated across the diode. At 2A, I would expect less than 2W, but there may be extra loss due to the switching frequency used. Overall, good unit for the money. I'd like to know why it is labeled as a 3A charger, maybe that is the average DC current for a 6v battery? I don't suggest opening up the unit and plugging it in. The heat sinks are tied to positive voltage, so you could get a good shock, even with GFCI protection due to the large capacitor.

Sped the little extra money on this charger and save a ton of money down the road over the cheap chargers that come with the razor products. Won’t burn up your battery like they do you dumb dumb

I like this cause you can change the charger heads for different things you need to charge

Love it! We're able to use this charger to charge 3 of the grandkids ride in toys. Much better than having a bunch of chargers laying around to keep up with.

Just what I needed!!
