Bests & Worsts Reviews from Amazon

I purchased these batteries in 2014. I use them for my Simple Human motorized trash can. I would charge them around once every 3 months. In the last 6 months, I noticed that some of the batteries started to fail. Today all but two batteries are working. I have Eneloop batteries from the Sanyo days and they continue to work. Some of the reviews say they these are identical I them. Maybe the batches they tested were but definitely not mine. BTW Eneloop uses their own proprietary technology of NiMH which makes them last very long. Some of these Amazon reviews eg NLee the Engineer concluded that these are the same which does not hold true for me. Regardless these batteries should not fail after 15 cycles of charging.
