Has anyone else has run into the same problem I've had with the 14500 Li-ion batteries supplied with the lightsabers? I've ordered enough sabers to now have about a dozen batteries and half of them didn't even make it to their second charge. That's a 50% fail rate. The other half recharge normally and still work great.
Given the high failure rate of the XTAR 14500's, I was wondering if anyone can recommend a different brand of 14500 battery that might be more reliable?
I have not had this problem; I’m using the original batteries on both my Diamond sabers (although one of those just arrived a couple weeks ago, so it’s not seen that much use). I have a recharge port in both, and I make sure to keep both sabers topped off. What I mean by this is that at least one of the sabers is typically plugged in all the time; Every couple days, I move the cord from one to the other.
Lithium-ion batteries don’t like to be run down to “fully dead” like you used to need to do with Nickel-Cadmium batteries. It’s not good for their long-term health, and every time you do that (or allow it to happen), you run the risk of the battery STAYING dead, forever. From your brief description, I can’t tell if this might be your issue or not, but I thought I’d mention it, just in case.
