I hear you ask 'Why?'...
Ever had more than one of the same brand/rating battery and one is flat and one charged battery (or one is old and one is new) and not known which one is which?  These simple heat shrink wrap covers allow you to tell the difference between your they look nice! 
Got a battery thats still has life left but the wrap has torn making it unsafe? Simply remove the old torn wrap, slide the naked battery inside the the new wrap and carefully heat the new wrap with a hair dryer."
