I bought one from AudioCubes which came in a very useful battery sizes plastic carry case. If you are looking for 'local' replacements/clones I suggest a look at ... http://www.batteries-online.co.uk/d/batter...MZ-N1_20489.htm or http://www.electricbirdland.co.uk/product.asp?P_ID=164 who both have a 'clones' at 9.99 Search for part numbers LIP-4WM or NH-14WM
