Anyone know the self-drain rate? I'm used to the lithiums that hold a charge unused for years. Does this particular lithium hold well, or leave you with dimness when you need it?

CromulentIt is not regulated drain. You slowly lose power of light as you lose juice. For normal use no big deal. If you throw it into high it will drain in about 30 min I found. Cool thing is that it only takes 25 min for mine to fully recharge.

LightGURUI mean self-drain, not use-drain. How well does it hold a charge if unused for weeks at a time? – I keep lithium lights like a Titanium Innovations IlluminaTi in my pocket, and a couple of 4Sevens Quarks in my go-bag and photography bag, for instance. I can use another compact light that will be ready to use even after weeks of non-use. It's useless to me if it self-drains as badly as the lights found on sites like dealextreme.

CromulentI believe it to be from 5-10% per year on rechargeable Li-on. A year would be storage time length and Li-on should be charged to 40% for optimal storage. Or you can also cycle and recharge it every few months if you want to store it above 40% (90%-100% instead) the effects should be minimal and depending on your needs may be worth it if you want the light ready to go at any time. Also don't store rechargeables at extreme temperatures, primaries ( non rechargeable ) are best for that. You can also double the rechargeable lifespan of the battery by charging to 90% when you recharge. In regards to lithium PRIMARIES ( non rechargeable ) these are best for long term in-light storage even in temperature extremes ( always buy USA PRIMARIES ). Always use quality cells and treat them with respect, flashlight Li-on rechargeables are not made in the USA but there are quality rechargeables from reputable brands . TLDR: I wouldn't worry much and buy a few spares. Im sure FACTOR uses a quality cell. I am NOT an expert by any means. I like flashlights. I still do, but I used to too.
