No! Stay away from the batteries that have "Fire" in the name, and batts that are on ebay, and amazon. You need a better battery like Samsung, Panasonic, Sony, ect, ect from a reliable vendor. 26550 may not be available in a lot of name brands, but search them out. This is not an area that you want to skimp on for safety's sake. Do a search on the "fire" batteries, there are plenty of threads on them and their problems.
