Run-Time Plot - Fenix E1

[Roy]

These runtime plots are for the Fenix E1 light using Alkaline and Lithium AAA batteries..

Equipment used is a Extech Mdl 401021 Light Adapter into a Radio Shack 22-805 multimeter with a PC interface that is using Scopeview software (V 1.08).

The vertical axis is in VDC and is equivalent to 1Fc@1Ft per 1 mVDC. The horizontal axas is in units of time.

Be aware that your actual battery milage may vary from that indicated by this runtime plot.



AAA Ultra Alkaline Battery
The runtime to 50% of max brightness = 3h

AAA Sinica Lithium battery.
The runtime to 50% max brightness = 4h 46m

Nice work Roy!

Looks like here is a case where the lithium really pays off for someone concerned about runtime and/or shelf life. Economically two alkalines would still be cheaper for most of us.

Love the graph though. A table top and then a plunge off a cliff. Nice.

What is a Sinica battery?

Sinica is a brand name.

Thanks, Roy. Your graphs are always appreciated.

i thought the Fenix E1 couldn't handle lithiums... the voltage was too high?!

Standard lithium primaries are fine in it, but not lithium rechargeable.

I get just over 5 hours to 50% with an Energizer E2 in my Fenix E1.

I use it to drain my partially used alkalines. It does quite well at that. I imagine the E0 may be even better at it.

Excellent info.

I have been interested in this light and the runtimes here are a bit more promissing than what I have heard.
