## Customer Reviews

### ⭐⭐⭐⭐⭐ Great battery.
*by J***H on April 6, 2012*

I purchased this for use in a portable headphone amplifier I built (AMB Labs Mini3) and since constructing it, I have not needed to open the amp, it charges well, lasts a decent amount of time and has been going strong for a year now! If you need a rechargable 9 volt, this will meet your needs and provide reliable performance for quite some time.Recommended.

### ⭐⭐⭐⭐ We have used these extensively in a metal detecting pin ...
*by J***A on September 22, 2016*

We have used these extensively in a metal detecting pin pointer. They run out much more quickly than other regulars 9V. However, this is a money saver really over time.Just bring along an extra. They also didn't seem to hold a charge very well in the beginning. But now they hold a charge much longer than before. So it's probably a breaking in process.

### ⭐⭐⭐⭐⭐ I can't be happier
*by S***R on July 11, 2015*

I used to use these for paintball and now I use them for my touch faucet. They last far longer than non rechargeable and as long as you have a decent charger they charge fast. Great product.
