The battery will be dead in about 3-4 weeks of non power. The problem
with the cells
is they develop internal shorts when sitting discharged. the trick of
blasting them
using a 100,000uf cap charged to 20-30V sometimes open those shorts.

Replacement is any 3nicad pack over 100mAH that can be fitted in the
available
space. Nicad lifetime in use or discharged varies all over the map.
