    • Rechargeable battery very nice not to have to buy batteries so often
Style: Flat Top
Really like that they are rechargeable. Use the flashlight every night when I have to turn lights out. Works great. No need for night lights

    • Very nice bang for the buck 18650 Batteries!
Style: Flat Top
These are very nice 3400mAh batteries. They work in and newe 18650(or non-Nebo compatible devices, though a piece of power clip and make them work on older stuff(that used the recessed female socket). Highly recommend for lasers and flashlights. My main pointer is a blue high drain class III. It will run through the provided 2200mAh battery in under 30min. After 10 it started getting less intense. Stuck one of these 3400mAh 3.7V batteries in(rechargeable) and now doesn't dim for 30-35 minutes. Stays reasonably bright for 1hr 20mins or so. ... show more

    • it fits
Style: Flat Top
I got the correct configuration/format so it fits perfectly. Be very careful about the positive terminal, often times the wrong format is ordered. Other than that all is well. Jury is still out on how long this battery lasts as they are still fresh but for now they lasts for 3-4 hours on my string light, a bit longer than my previous pair. ... show more

    • Reliable 3400 mAh Performance
Style: Button Top
This 3400 mAh 18650 battery has been outstanding in real‑world use. I charged it fully before installing it in my device, and the difference compared to many “high‑capacity” batteries is night and day. It delivers steady, long‑lasting power and easily makes it through the night with plenty of charge left. The performance feels honest, consistent, and far better than inflated‑spec batteries I’ve tried. For anyone who needs a dependable 18650 cell, this one is absolutely worth it. ... show more

    • Good value
Style: Flat Top
I gave it a 3 only because they shipped me the wrong style. I needed button top but sent me flat top model. But I just added some aluminum foil and made my own button.The battery it's self is great for my little radio. I'm getting about 10 hours of play out of it. My original battery only got about 8 hours when brand new. So good performance from the replacement battery. ... show more
