I received my new Fenix L0D Premium Q4 a few days ago. It's a keeper! I emailed Fenix to get an answer about the eternal question around here about what to use to lubricate the single o ring. I also asked about using the 10440 Li-ion cell, (knowing that it's not reccomended and will void warranty etc) based on thier experience with returns etc. I received the following in reply:
"Thank you very much for using Fenix light, very glad to hear that you can get the good service from the fenix dealers, the O-ring is made of rubber, we usually use the Vaseline to lubricate it, and I don't know whether the petroleum based product will made chymistry reaction with the O-ring, I think the Vaseline can be seen everywhere, so for safety, you had better use it.
We don't suggest you use 10440, because the volt is so high, reaching 3.7v, it will do harm to the circuit.
Best regards!"
Vaseline and rubber don't sit well with me so does anyone know if their response is accurate? Also they seem sure about the 3.7 volts harming the circuit..and I thought the 10440 cells measure around 4.1volts or so hot off the charger so that would not be good. Any comments?
