The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged. If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will switch into its ``trickle charge (maintenance charge)'' mode and keep the battery cartridge fresh and fully charged.
