Do you want to maintain the original, "correct" LOOKS of the battery in your vintage restoration? We suggest our replica Battery Housing (sold separately) that on the outside looks exactly like the original battery that would have been in your bike, but on the inside is simply a hollow box in which your new battery will fit and function flawlessly! Then top it off with a replica Mareg or Bosch (also sold separately) brand sticker for the finishing touch!
