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