Question: can we replace batteries?
Document: Easy to use and replace batteries. Perfect lighting for on my mantle in the hallway, I couldn't have asked for anything more perfect.
it was as expected item looks real kindles ,but no longer works after 6 hours , but you can replace the batteries .looks good , looks real flame kindles and safe.
I ordered this pack of 12 flameless candles and I needed all 12 of them for our event. However, based on other reviews, I was prepared to take my chances that one or two may not work & I planned on buying a few batteries to replace those potential duds, and others I had, as needed. Wouldn't ya know, 1 out of the 12 didn't work!
My husband and I received these lights as a gift from my sister-in-law. They are really nice with the changing colors. After reading the reviews and found that some customers said that all the lights did not light, I checked all of ours. 10 of the 12 worked. I quickly unscrewed the battery door and replaced the batteries and now they work perfectly! Only took a minute to get them working. They use the CR2032 batteries so not real expensive if you have to replace a battery.
I bought this set going on over 4 years ago now. I use them over and over again. I love them because I can have the look of the candles without worrying about my little daughter or the cat knocking them over or burning themselves. The batteries are easy enough to replace. Mine are still in working order and I am going to add another set of 12 to my existing set. I have acquired a few different kinds here and there at a cheaper price but the flicker isn't quite the same.
They provide a really nice soft light like candles without the heat or danger. No worries about falling asleep with these candles going! And while I only just bought them, the battery life seems pretty good so far. Haven't had to replace any batteries yet, and I've left these going overnight several times, so that is many hours of use. Obviously they last longer than actual tealight candles.I am very likely to purchase more of these, because for all the downsides, they are pretty neat!
They do not last long enough for me. They have a little battery you can replace in them but for some reason it does not connect well. They would last longer if they would connect better.
The battery comes right out and is easy to replace. They take a standard 2032 watch battery which you can get online for next to nothing and they last for quite a long time. They work great in anything that should use a real candle and are safer than having a lit flame in your home. Considering their price, they are easily disposable if something happens to one so you don't feel taken if it breaks.
I had to go out and buy a whole other 6 pack (about $7) just to replace the one defective one in my pack. VERY frustrating! While you think you may be getting a good deal on these, you can see where it ends up costing you more in the long run. This company definitely needs better quality control on this product! When I buy brand new things, I expect them to work!
I bought these to use in replace of a real candle for our pumpkin this Halloween, and they work great. Nice and bright, and flicker just like a real candle. It was also nice to be able to leave it on for long periods of time without having to worry about a real flame being in there. I've only had to use one throughout the week, and it seems to still work, which is great. I will be buying more in the future to use around the house and office.
Answer: yes
