Yep, holes to plug but painting is the worst part. The colours never match and I certainly don't wish to repaint a room.

Dunno about that, Wes still list Japanese nicad cells (Sanyo or Panasonic) although that may cease at any time in the future.
Not sure that age matters much either as they seem to last forever until the first charge.
Which raises yet another. Current model Sennheiser cordless headphones use nicads as do the cordless headphones from Wes. I certainly don't want to throw the Sennheisers away. :(
