Your call. Honestly, Eneloops compared to other NiMH batteries are way better. Newest versions of regular Eneloops are rated for 2100 charges. They have an excellent long self discharge rate and they have good consistency with quality and having the cells all at the same voltage when you buy them in a package. Problems start with buying lousy cells. I’d just not store batteries in the light longer than 24 hours to avoid any possible gas build up and you should be fine. Inspect your light and batteries for safety before each use as you would any other tool and you’ll be fine.Yeah the Vizz is what threw me off, I actually own that headlamp. Wondering if I should avoid the eneloops in it?
