Our battery wraps are sized to fit a wide range and styles of batteries.  They measure 4 inches in length and 2 inches in width.  They will fit batteries from a 650 mAh to 1100 twist.  To use on the smaller batteries, just trim the top and or the bottom of the wrap, depending on where you want to place the design; to your desired length. Instructions included, with your purchase.  Note: Some designs, if cut down for a 650 or 900 may loose too much of the design and should only be used for the longer (1000 & 1100 mAh twist type) batteries.
