Looking for a 14505 non-r/c 3.6v battery as a backup to keep in car.

I'm looking for a 14505 to use as an emergency backup battery in my car. I keep a couple pairs of CR123's as backup for my quark should the 17650 die, I need a backup for my E12 now that its li-ion only. Note I do carry a real 14500 spare, this would be a last ditch thing so it will probably sit awhile, hopefully they're as safe in storage as CR123's.

Prefer the largest capacity cell but also hope to find something capable of >2A discharge rate.

Hi,

Pardon me (and I don’t mean this in a sarcastic way), but what is the benefit of that 14505?

Is it that it’s a larger capacity than a normal 14500 and has longer shelf life?

But, isn’t the voltage less than a normal li-ion (i.e., 3.0V vs. 4.2V), and it’s just a primary/non-rechargeable battery, right? Also, is the battery just slightly (5mm?) longer than a 14500?

I think he might be looking for the extra long shelf life like the lithium 3v cr123’s supposed 10yrs or so.

I wonder if those boost/buck drivers (that run on 1.5vdc or 3.0vdc stacked-boost/4.2vdc -linear regulator) would work?

Possibly get a host that holds 17mm, put one of those in it and see if it can boost the output to a XP-G2 (1500mA is 300% rated capacity)

I know they have a CR123 host, the Ultrafire 602C, it holds a 17mm driver, and 16mm star (I built 2x of them with the 101-AK-A1 and use 16340 Li Ion batteries in em and even at 1400mA drive power they get VERY hot…and are suprisingly bright for thier size)

I think maybe once my finances are stabilized I will get one and see if the CR123 and boost driver will run it

Actually maybe a full sized Convoy host and this driver and stacked CR123’s (6.0vdc) running a XP-G2

Or a Zener diode Nanjg 105C and stacked CR123’s (6.0vdc)

The reason I after a 14505 and not a standard 14500 Li-ion is for the extra long shelf life. Like I mention I do carry a spare already so I would very rarely need to fall back on this battery, it would just be an absolute last chance.
Last night working on my moms water heater for a couple hours I burned threw the 17650 in my quark and both the 14500 in my E12 and the one backup I had and was working on my only pair of backup CR123’s in the quark, I had forgot to take my headlamp so I didn’t have anything that would of ran on the only other batteries had those died- AA Alkaline’s. Since my E12 no longer runs on AA/NiMH I want to have a last resort I can leave in the car in the summer heat for extended periods and have it be there for that one time a year I need an extra 45 minutes of emergency run time.
