How do AW 750mah cr123 compare to energiser primarys

[losthope]

As per title how does Li-ion stack up against single use lithiums ?

Forgot to add it's the Protected AW 750mah cr123 Li-ions I am looking at getting.

They are for use in a Fenix P1d-ce

No expert here but,AW 750mah cr123 Li-ions may be slightly brighter at first but you will get no where near the run time you would get from a primary cell.Also they don't like the cold/heat that a primary can take.However if you plan on using your light a lot and will be going through a lot of batteries rechargeable may be worth it. Hope this helps

The P1D was not designed for a LiIon rechargable, so the circuit will be bypassed and the LED will run direct drive from the battery.

Med and Max will appear close to the same brightness and you will lose low altogether. Med is actuallly a bit lower and longer running but you can't see much difference.

In some very rare cases the circuit or LED can be permanently damaged, but if you only run it for a few minutes or have active cooling that should not be a problem.

If you run LiIon your warrenty is null and void.

If you run a search on the reviews forum I know there are runtime graphs for that light and LiIon battery.

The highest capacity RCR123's have a bit less than 1/2 the capacity of a good primary battery. Not a problem of course as they can usually be recharged upwards of 50 times before loosing any performance, so it's almost certain you'll get your money back out of them if you use the light often. The other issue is power handling, the normal liCO (most cells labeled 700+mAH) cells and their protection circuits can only handle around 1 amp reliably. More current draw from incans or very high power LED lights can trip the protection circuit or decrease the battery's operating lifetime.
