Lithium primary 3.6v battery for my Jetbeam MKIIx?

[slaps]

I've been looking at Saft LS 14500C 2700mAh High Capacity Lithium Batteries. Are these batteries a good match for the high output Cree AA lights that are all the rage? I would like Li-Ion output without the worry of overdischarge and low capacity. If the only downside is their $7.00 apiece pricetag I'll give them a try. What do you think????

What is the voltage of the Saft cells? I think they'll be fine . . .

What's the max discharge rate on the Safts? I remember reading about other Safts and the discharge rate is really low and not enough to support a high power LED of any brand. Perhaps these are different, but something you should look into.

I believe the voltage is 3.6volts.

Nominal capacity 2.7 Ah
(at 1 mA + 20°C 2.0V cut off. The capacity restored by the cell varies
according to current drain, temperature and cut off).
Open circuit voltage (at + 20°C) 3.67V
Nominal voltage (at 0.5 mA + 20°C) 3.6V
Pulse capability: Typically up to 150 mA (150 mA/0.1 second pulses,
drained every 2 mn at + 20°C from undischarged cells with 10 μA base
current, yield voltage readings above 3.0V. The readings may vary according
to the pulse characteristics, the temperature, and the cell's previous history.
Fitting the cell with a capacitor may be recommended in severe conditions.
Consult Saft)
Continuous current permitting 50% of the nominal capacity
to be achieved at + 20°C with 2.0 V cut off. 25 mA
(Higher currents possible, consult Saft)
Storage (recommended) + 30° C (+ 86° F) max
(for more severe conditions, consult Saft)
Operating temperature range - 60°C/+ 70°C
(Operation at T different from ambient may lead to reduced (- 76°F/+158°F)
capacity and lower voltage plateau readings. Consult Saft)
Can anyone decode this info for me? Will it run my Jetbeam properly???

No, the current ratings on that batt look way too low to power your light.

That's OK. I sacrificed a Duracell CRV-3 battery pack tonight. I took it apart and put it in my Jetbeam MKIIx. Wow!!!! I am now a believer in 3.6volt AA power. Much brighter and no recharging. I only use the light occasionally so the duracell should last quite a while.
