I know that the original batteries teu (r) it is, but I've given up for me to tease me about it after I had to annoy me in the past, sometimes through replicas (also of renowned brands in the battery area).
For an original battery I can eg be safe (in my experience) that I can use non-use yet it after less than a year (of course after a new loading process). In third-party batteries it happened to me frequently that they were no longer "responsive" or to load. Others may have had different experiences, me it's just important that I can rely on the battery and does not need to expect a default rate.
