GRACETOP 8 Pack Rechargeable 14250 Battery 3.7V 1/2 AA Lithium Batteries Can Replace 3.6 Volt LS 14250, ER14250, CR14250 Disposable Battery for Laser

I recently switched to these 8-pack rechargeable 14250 batteries, and they’ve been a great find. They’re a perfect replacement for the 3.6V LS 14250, ER14250, and CR14250 disposable batteries. The 3.7V lithium batteries provide reliable power for my laser devices and other electronics. I love that they’re rechargeable, which makes them more eco-friendly and cost-effective in the long run. The performance is solid, and they hold a charge well. If you need a dependable and rechargeable alternative to disposable batteries, these are an excellent choice!

I have a low power wireless device that uses LS14250 battery. These batteries would work in place of LS14250, except for lower capacity (LS14250 is usually 1000mAh+).For my application, it will take a few years to get through all 8 batteries before I need to start charging them.All batteries came in at 3.8 - 3.9V except for 1, which came in at 4v.
