My AW 2900 mAh 18650s are getting a little long in the teeth, so I'm looking to replace them. It's been a while since I've bought new batteries, so I have some questions that I hope you can help me with.
1. I have always been told that the IMR chemistry wont start a fire if the cell fails catastrophically. Is this correct? And is the INR chemistry as safe as the IMR chemistry? If not, what is the main difference?
2. Would it be safe to run unprotected INRs in single cell lights? I generally use a high quality charger (Xtar VP or VC series or Nitecore SC series) and I almost never run my lights dry. I also pay attention to the voltage reported by the charger when the charge cycle has ended.
3. Would it be safe to run unprotected INRs in multi cell lights? I wouldn't put cells in a light if they differ more than 0.02 volts when they come off the charger and I almost never run my lights dry.
4. Would Sony VTC6 or Samsung 30Q be a good choice? My lights don't draw a lot of current, but I want to be able to charge single cells fast on a Nitecore SC4 and it's my understanding that INR allow for faster charging.
5. I have a couple of Eagtac 3500 mAh in my Olight M3XS-UT. Which kind of cells are these? NCR18650GA? What chemistry are those and what's the maximum safe recharging rate?
Help me not burn down my house. Batteries are so confusing these days
