Hello all,
This is long, so take a seat.. I am considering selling these new bare cells, but first I need some input from other members.
First the details: /ubbthreads/images/graemlins/smile.gif I have acquired quite a few brand new bare 17670's, Sony #US17670GR. I am keeping enough for all the lights I have and some spares, but I will still have about 80 to sell. Fully charged, they run my L4's for 55-60 min. My L4's run noticeably hotter though due to the fact that with the lower supply voltage, the converter is working harder, thus more heat. The additional heat is the ONLY downside of using these. Feels good to never have to buy 123's again. If I decide to sell them, they will be $5 each plus $5 shipping in the US. If the interest is high, I may put a limit on each person so everyone who wants some gets them. I am not getting rich on these. I didn't get them for free. I don't have use for all of them, but as hard as they are to get, I couldn't pass them up.
Now, my concerns: /ubbthreads/images/graemlins/frown.gif I need to know the liability involved in selling AND shipping these bare cells. Please don't tell me it's no problem just to get me to sell them. I'm not that stupid. I'm a 40-year-old man with a lot to lose. The reason I am so concerned is this:
I have personally witnessed a lithium battery explosion. The plant that I worked in had a hydraulic press controlled by a PLC. This PLC was mounted in a 12Ga. stainless steel control cabinet about 3ft wide, 5ft tall. Inside the PLC, there was a CR2 battery for memory backup. One day out of nowhere, there was an explosion inside the cabinet that completely blew the door off (ripped off latches and a 5ft long welded piano hinge) and destroyed almost everything inside. There was absolutely nothing left of the PLC to inspect, but the best anyone could figure was the PLC power supply malfunctioned and was slowly charging the battery until kaboom. I am sooooo lucky that I was not working on that machine that day. It is obvious that this group is full of highly intelligent individuals, but there is always someone that seems to screw it up for everyone. Hopefully, that "someone" reads this story and thinks twice about using bare Li-Ions before they have the knowledge and equipment to charge them properly and safely.
Now for the big question. Would I be taking a big risk selling these? Thanks for taking the time to read. I look forward to your responses.
