"Bought a couple of these to use inside of some Malkoff Devices w/High-Low Ring set ups I have (M61 SHO in MD2 & M61WLL in MD3) & they have been perfect. Doesnt give full output on the M61 SHO configuration but i knew that from the start based on voltage. However, they charge fast & give a very good amount of light output in this configuration. The MD3 that has the M61WLL is another story entirely. This is the perfect rechargeable to place inside for daily use/woods use. I haven’t had a single issue & I get full output for a good alount of time. Highly recommended investing in some of these."

Perfect Replacement for an old O-light
"Finding replacement batteries requires a bit of research but I'm glad I chose this for my old M1X Striker by O-light. The price for this battery is absolutely worth it with it's giant capacity and built-in USB-C port. The M1X has a turbo of 1000 lumens so the 3600mAh capacity ensures that I can hit turbo often without having to recharge it for weeks at a time. Depending on your O-light battery situation, you either have to use their proprietary magnetic charging cable or a charging dock. With this battery, having the ability to charge via Usb-C or a standard dock is really convenient for home use or travel. If there are any disadvantages to incorporating a Usb-C port into an 18650, I haven't noticed it yet. For now, it's an awesome little battery!"
Q&A
- Can the Nitecore NL1836R 18650 3600mAh 3.6V Protected Lithium Ion (Li-ion) Button Top Battery with Built In USB-C Charging Port, be used in a vape device?
- I am sorry but we have no information on this, so are not able to confirm one way or the other.
- Repeat customer. What is your return policy on rechargeable batteries? If 3.6V is sub par, can I swap for 3.7V? Nitecore NL1834R is discontinued.
- Battery Junction offers a 30 day return policy if the battery does not suite your needs. I am not finding an order for a Nitecore battery on your orders. Are you sure you purchased it from Battery Junction?
