I have a Zebralight H600w, Nitecore EC2 (discontinued) and Nitecore EC25 (discontinued). Each use a single 18650. My wife and I are headed out for an adventure in a few weeks, and we were hoping to grab some new cells that would last quite a while before recharging. I picked up 2 NL 1840HP cells from Nitecore, their new 4000mAh 18650 cells with 10A discharge current, designated for high-drain devices. Please bear in mind that I know next to nothing about the complex world of flashlight and battery (or cell?) circuitry. I'm here to confirm or deny compatibility of these cells with the lights mentioned above. One of the 5 warnings on the package of the new cells admonishes: DO NOT use the battery if its discharge current does not match your product. We've been using Nitecore NL 183 2300mAh cells – along with some cheaper cells – in these lights for years, and never considered their compatibility. Should we be concerned about using these new 10A-discharge cells in these lights? Thanks in advance, from a guy who just wants to go outside and have some reliable, quality lights (and hasn't graduated from Flashlight State University).
