The whole pack didn't even last two months.  Not worth the purchased..
Batteries did not last 2 months, not one but ALL OF THEM.  The first one expanded in my ceiling fan remote and died within days of using.  The rest pretty much didn't last more than a week, the remote was hardly used.  These off brand is not a quality product.  I'm not buying off brand batteries ever again after this purchased.
