Review: Perfect DIY Battery - 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.
Review: Great battery - Perfect for powering decoys.

Perfect for powering decoys.

### ⭐⭐⭐⭐⭐ Nice
*by M***C on February 14, 2024*

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.
