Review: Great batteries for a greater price! - I bought the 2 pack as I have a duet of Duets running original batteries, which means the controllers had about a 2 hour time off the charger. After replacing the worn out factory batteries, and taking these through a full discharge/charge cycle, I now have useable Dueat Controllers again! With ~$11 purchase, I just added years to the life of my Duet systems. I am a happy customer!
Review: Value For Your Hard Earned $$$? I don't think so!! - One battery functioned as it should have. Very well and as expected. The second was a HUGE disappointment, it lasted less than two weeks and died (+ would not take a charge from any charger in my home. Strange as I own (7) seven li-Ion chargers all of which work EXTREMELY WELL with other battery packs.

### ⭐⭐⭐⭐⭐ Great battery!
*by J***K on October 7, 2016*

My remote's battery would not hold a charge for very long. So I headed to Amazon to see if there was a replacement. This battery is perfect. I charged it once and my 1100 remote has been working for a week now. Great price for a great product. Brought my remote back to life!
