Review on 10 Pack CELEWELL CR2032 Lithium Coin Cell Battery - High Capacity 230MAh, 3 Volt Button Battery For Devices - ECR2032 Replacement - 5-Year Warranty (Not Suitable For Thermometers) by Dana Wood

I've ordered these twice now, one set in 2017, and again this year to replace/supplement that first set.We need around 100 CR2032s for all the leds, decorations, and tea lights we use at Halloween. So I bought these for the good reviews and one of the better prices for a bulk set. The props and lights are turned on for around 6 hours, and then the batteries get taken out, put in coin collector sleeves for storage, and then taken out again next year. I check each year with a battery tester, and usually all but one or two are in the green. That first set lasted about 2 years this way, with maybe 20 still usuable this year. We recently started putting up some of the lanterns for Christmas, with the same led tea lights, but we run those 24 hours a day. Last year the older batteries lasted about a week before fading to the point you couldn't see them through the colored glass (but there was still some light). This year the older batteries lasted between 3-5 days, some of the lanterns going faster than others.
