I use Panasonic NCR18650B 3400mAh in my Zebralight H600MKII. I charge them with an Intellecharger i2. I think I had a cell die on me (does that happen with these?). It seemed to work fine one day then the next, my Zebralight would turn off after clicking it on. I put the battery in my intellecharger and it got hot and would not hold a charge. Whats going on? I only used that one cell for about a year, is that about the correct lifespan? Also some of the plastic near the positive and negitive ends is starting to tear a little.
After reading, it does concern me to have these Li cells right above my face. However, it would seem that there is some protection built into these cells (when used as single cells, as I do in the Zebralight) and the Zebralight itself has protections built in. It would also seem that if a battery does vent, it will not spray on my face when it is in that headlamp.
What if somehow water got inside the body of my Zebralight? I use this while I ride my bike, and I ride in the rain sometimes. Would having a 'protected' cell protect me if water got inside the headlamp housing?
The other question I have is, would using a 'ml-102 version 8' (google it, as I cannot post links to sales sites here per forum rules) with these same batteries as a backup charger for my cell phone be safe?
