I started to collect old Nikon film cameras and most of them use DL1/3N or two LR44 batteries. This Celewell brand works really well. It powers my camera reliably and at this price I could have a pack of spares in my camera bag at all times.

I was in need of some replacement CR2 batteries for the sensors in my SimpliSafe system and these CELEWELL batteries fit the bill perfectly. Way more affordable than the big name brands and zero issues with them in place--they're doing the job just fine!

They are not high quality Duracell, but at this price point, it doesn't matter for my use.

I just received these batteries, so I can’t speak to their longevity in use or in storage. That being said, I ordered these in early August 2023. The manufacturer date is shown as April 2023 and they indicate a 7-year shelf life, expiring in April 2030. I put 2 batteries in my light and it fired right up. These seem to be a good choice for my needs. Way cheaper than any of the name brands. Hopefully they last in my device and store well! They arrived promptly and in good condition.
