Maplins or Colemans in N.Shields, however mine is SLA (sealed lead acid).
Someone on here had a nimh battery pack made up somewhere local, much lighter.
Thanks for the replies lads.
Rod, I've obviously still got my tiga charger, would the place you got your replacement put a connection on the battery to match it?
My battery looks like its had it, not holding a charge at all now.
Its a 6v 8A Ni-Cd, has anyone ever bought a replacement?
