12V 1.2Ah Bare Leads

Purchased this battery for my trip-wire car horn camping alarm. The horns were intended for cars undoubtably, but hey I’m a DIY guy. The horn is rated at 12v-5amps(watts never tested by myself ) so when I found this battery I wasn’t sure if it would be powerful enough. Turns out the battery worked great, although the horn doesn’t reach the maximum loudness probably due to the low watt output, it is still very loud. 12v train horns don’t work with this battery, but 14v does. Battery charges fairly fast and I haven’t encountered any heating issues while in use or while charging. Battery and charger are light weight which makes it perfect for my hiking and camping expeditions. Very pleased and will buy more in the future for other diy projects. Shipped fast as well.

Works great. Was a great upgrade from the original 2300mah battery.

Nice battery. As others have said, no relevant instructions on charger, but research elsewhere suggested, and experience now confirms, that it's basically plug into power outlet, connect battery and wait until led on charger changes from red to green to show full charge. Battery life and longevity as yet unconfirmed.

So far it works great. Only thing I don't like is the cheap charger. The battery should be charged at 12.6V 1Amp but the charger is giving it 13V at 400mA. It charges all the way to 13v. It does at least use constant current constant voltage. Nice little battery pack though. Love the barrel jack connectors, perfect for what I was doing.

I’m sorry, but I love this battery. Charges pretty quickly, but lasts a long time, a little “pricy” for my model building budget. I originally bought this battery to power the Arduino in my (self printed) 1/1000 Crossfield Class Federation Starship. But I liked playing with it so much I have yet to close up my U.S.S. Discovery. Our neighborhoods power went out for three days. I took this battery, about 100 leds and lit up our (above averaged sized) front room. We had three nights with the kids and my mother-in-law playing games, doing puzzles or even just talking. I still wish I had a generator though, so don’t go thinking you can power your refrigerator with this. But if you are thinking that chances are you can’t read anyway so…

Great power unit for projects

This was the perfect thing to turn my wife’s spectra S1 breast pump into basically a portable unit. Apparently this battery is so strong it lasts twice as long and doesn’t lose its power compared to the much more expensive portable version( the S2)

Works well
