pkh,
you want to store NiCads in a discharged state.......otherwise they develop a phenomenon known as 'memory' where they will only charge up to the capacity they were stored at...if they were stored at 95 % then they will charge 5% and maybe dischage 10% and be stone cold dead. Very very uncool and the epitaph of many proud aircraft over the years. Just my .02 worth.
