Purchased these for a few flawless LED candles that we had around the house for Christmas decor. After seeing the price, I was very excited to get a battery that according to other reviews would be great compared to the price of name brands batteries. A few of my candles took 3 batteries and some took 2, but within a week of installing these they started to die. Now, these candles were on a timer to turn on each day for six hours. That means the life of these batteries wasn't enough to for three of them to power an led candle for more than 42 hours before they started failing. Not worth the money I paid for this product.
