When I bought this product, I feared it might be too good a deal to be true. Unfortunately, testing confirmed that fear. This device should not be sold as a battery charger because it was not designed to be a battery charger -- it is a simple, unregulated, wall-wart power supply with alligator clips.

I received a charger identical to that in the photo. It's marked as a model 41A0163 with a listed output of 6V/12V and 500 mA (the voltage is switch selectable). Because there are no other specifications, I tested it to determine its actual voltage output. I found that in the 12V position this wall-wart style power supply outputs an unregulated and unfiltered, full-wave rectified voltage, of 12.3 Vrms and 17.4 Vpeak.

If you measure the output with a digital multimeter, you'll measure the average value of the full-wave rectified voltage, at 11.5 V. But that's just the average value of a waveform that peaks at 17.4V. If you place a small capacitor across the output, you'll measure the peak voltage.

This product is not really a battery charger, but mis-marketed as one. Instead, it's a low quality wall-wart power supply with alligator clips attached. It will supply sufficient current to charge a small, several Ah, battery in a few hours, at the risk of overcharging and permanently damaging it. It has insufficient current capability to charge large batteries in a reasonable time, but may charge then over the course of several days. Those using it with large batteries probably haven't done much harm to their battery, as larger batteries will take a long time to overcharge at the small current this charger outputs. But if you leave it connected indefinitely you'll probably damage even the largest batteries.

Arrival of very hot weather seemed to coincide with annoying beeping of my house alarm. Further investigation determined that the battery needed charging.

12V sealed lead-acid batteries of the type used in many house alarms are pretty expensive. Fortunately, they are rechargeable. This charger only costs about 1/4 to 1/3 of the price of a new battery.

I let it charge during a weekend for a total of about 12-16 hours. I don't recommend leaving things like this charging while you're away from home or asleep, just in case.

No more beeping, so it seems to have worked. The charger does NOT have an LED light or other feature to indicate that it is "on" or whether in fact it is "done" charging.

This is about as simple as a charger can get. An AC plug in transformer with a voltage select switch and color coded alligator clips at the end of the cord. It charged both of my batteries (6 and 12 volt) without any problems and gets only slightly warm to the touch. The charge rate varied between 400 ma to 40 ma (depending on battery condition) and produces pulsating DC.

Bought it from e-com electronics to charge a Power-Sonic 6v SLA battery.
The charger came without the alligator clips and started to over heat and melt in the middle after charging the battery for 9 hours ( and yes I checked the polarity before connecting to the battery).

I bought this to use on my low amp light but it did not work. I called to return it and they told me to keep it and they would refund my money which they did. I purchased a different one and that was not much better. Don't try and be cheap when it comes to charges because if the charger doesn't charge the battery you only paid for disappointment.

I was in need of a charger for the battery of a Child's Battery Operated Motorcycle. Purchased it used only catch was the charger had been misplaced.

I had purchased one from another company and it was poorly made had to send it back. This one I've had no issues with it at all. It will charge batteries that require a 12vlt or 6vlt charge. It has a switch that you can flip to adjust for the voltage.

This charger works fine -- my only gripe is that I wish it had some sort of indicator light to tell you that it's working, or that it's charging. You know, a red light while the battery is charging, a green light when it's done. Other than that, it's fine.

Complete waste of money. I did something I've never done before, and went with a suggested pairing "others who bought this battery bought this charger" without bothering to read reviews. My mistake. This is not even a battery charger. As other have stated it's a crappy 12v power supply with gator clip ends - it should not be sold as a battery charger. Do yourself a favor and buy the Black and Decker charger seen here:

http://www.amazon.com/gp/product/B0051D3MP6?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

$19.00, but actually trickle charges 12v or 6v batteries and shuts itself off once the battery is charged.
