Early winter 2021, I purchased 60 rechargeable C cells to power my battery-powered window candles through the Christmas season. Most of the batteries I purchased were Ray-Hom, but I maxed out the quantity I could purchase from them, and I purchased Amazon batteries to complete the set.For the 3 months I kept the candles in my windows in 2021-22, I had no issues. I charged all the batteries once, and they all lasted all season, powering LED window candles that were on from dusk to dawn daily.When not in use, the batteries were stored in a cool, dry location.Fast forward to this year. Once again, I charged all 60 batteries and loaded up the window candles for the season. The Ray-Hom batteries are performing as expected. After two weeks, they are maintaining a strong, bright light, and none have required any further charging.In contrast, several of the Amazon batteries are not holding up. There are several candles that have gone dead multiple times, in just the past 2 weeks, and all the ones that are going dead have Amazon batteries in them. I have recharged these batteries multiple times, and they are dead within 3 days.Unfortunately the Ray-Hom batteries that I previously purchased are not available on Amazon at this time, so I am looking for an alternative to replace the Amazon batteries.I would purchase more Ray-Hom batteries if I could, but I do not recommend the Amazon batteries if you want them to last multiple seasons.
