Sigh... Ok, let's walk through this and then I'll bust your chops at the end.
This is the data they provide for the batteries:
Working Voltage:3.2V and Peak Voltage: 3.6V
Peak Voltage is what you should expect with the battery fully charged just off the charger. We will use this value as the worst case for calculations.
Charging cut-off voltage: 3.6V
Discharge cut-off voltage: 2.2V
Please never overdischarge battery below 2.2V/cell
Ok... here is a small downside. There are no protection circuits on these batteries. That means there is no cut off for under charging your battery either. During use you will notice vapor probably drops off to almost nothing around 3V or above so you'll recharge it long before it gets this low. But batteries have a self discharge rate. Leave them on the shelf long enough and they will very slowly discharge themselves. If this battery goes below 2.2V it's probably ruined and it's likely it won't take a charge again. Unlikely you would leave them that long but you might and then there is that problem with the button getting stuck or something like that.
Charge the this battery with LiFePO4 RCR123A smart charger.
Yes, you will need the charger specifically for these batteries. It will not work for other kinds (and it's probably just for this size as well) and other kind of chargers will not work for these batteries. charge rate, and cutoff, and stuff.
Capacity: 750 mAh
Maximum discharging rate:< 550 mA
Now this is a real problem. Remember we figured 1.75 Amps (1750 mA) with 4.2V through your 2.4 ohm atty?
Well, 3.6V through your 2.4 ohm atty is
1.5 Amps. That's 3 times the max discharging rate for these batteries. No, everybody doesn't ruin these batteries or have them fail (remember the pulsed application) but you are way overdriving them. At the very least you will get much shortened overall life out of these before they need replaced. No, I have no idea why any vendor would sell these on an e-cig site... (yes, I know you were looking on the Tenergy site but they are resold by one or more of our vendors). They do have the same chemistry (or maybe some other "safe" chemistry) batteries rated at 4C or more but I'm not sure they come in the right size for your mod. I would recommend quality, protected Li-Ion batteries.
Here is a handy dandy calculator for Ohm's law:

Maximum charge current: <550 mA
Yes, I meant ohms. Ohms, amps, volts, watts - it could as easily be Babylonian to me. I hated physics. Correction - I hated both physics and chemistry. Biology was my strong suit. LOL - I just don't want to explode or ignite and I really had my heart set on that mod.
Surely you can find other batteries for that mod. What are you vaping now? If it's some regular kit type of thing do you know the voltage you're running through your 2.4 ohm battery now? If it's giving you the vape that you prefer then you're going to want to stick with the same voltage. If you can't do that then get a decent battery and use different (ohm) attys to get the desired result.
Oh yea, I forgot the busting your chops part
DON'T BE LAZY! You could put your eye out with that thing. haha.
Seriously though, people are concerned about safety but they don't want to put any effort into educating themselves. There just isn't any one answer and there is no such thing as completely safe. Especially with rechargeable batteries.
