For those of us living in places where we have winter, a pretty important aspect of preferring Lithium batteries is as simple as... getting any power at all. Lithium batteries are some of the least bad when it gets cold.
I guess I should have clarified that my gripe was against rechargeable lithium batteries in an EDC LED light, and I still feel that way. I'm sure that there exists a superbly designed, rechargeable Li-on compact LED flashlight, that will perform dependably for years, but I haven't seen it so far.I do use the lithium dry cells (such as the Energizer Ultimate Lithium) for long life and cold weather performance in my flashlights.
I may have ordered this one too. .... (Image removed from quote.)
Personally, I think Lithium Ion batteries are a mismatch with an LED flashlight. They tend to discharge themselves over time (some, not all) as well as loss of capacity (10-20% per year in some cases). Most LED flashlights have run-times of over several hours, which is sufficient for most applications. There is also a minor but significant fire risk, using Lithium cells, especially in harsh environments.An alkaline cell seems much more suitable, as they tend to hold their power over longer periods of time, and have a longer shelf life, up to 10 years in some cases. Also, an alkaline cell is much more available when you need one, unlike a way to charge a rechargeable light when you really need it.Re-edit: I meant to refer only to rechargeable Lithium Ion, batteries, not the Lithium cells which substitute for alkaline cells. I based my opinions on personal experience and research.Quote from: enki_ck on January 14, 2013, 05:16:00 PMSorry, but most of what you just said isn't true. More the opposite. And you're mixing up Lithium primaries and Lithium rechargeables. As a rule Lithium primaries are SAFER than any alkaline for flashlight use. They have a much longer shelf life, +15 years, and they don't leak. As for Lithium rechargeables, there's no danger in using them in single battery flashlights, the dangers you speak of are only if you use mismatched (maybe even unprotected) Lithium rechargeables with different power levels, when instaid of powering the flashlight, the the stronger battery starts charging the weaker and BOOM. And those cases are due to user error, not the batteries themselves. As for loss of capacity, good quality protected rechargeables like the AW ones have a very low self discharge rate, almost negligible.
