Battleship Live Game (Broken) (Bath)

Battleship Live Game that was working fine when used a long time ago but unfortunately the batteries were left in it when it was put away so the contacts in the battery compartment are corroded. Comes with all the parts, board, tower etc. Shame to send it to landfill so hoping someone who knows how might be able to fix it and get some use out of it. Collection from Central Bath.
