If you buy batteries from ebay, I don't recommend buying from member r-lsales AKA RL-batterydepot. I bought some 26650 batteries from him twice, both times one of the two batteries were completely dead and would not charge & when I contacted him he would not replace it. I had to open a case against him, which I won. When eventually returned to him later, he made a statement to ebay there were arc marks on the battery which was a fabrication. The battery would not take any charge at all, no current would flow to or from the battery & returned in pristine appearing shape.
It's one thing for a seller to send crap that doesn't work, another when they lie about it, he shouldn't be allowed to sell on ebay.
