Why doesn't the ccd camera light up after charging for five hours?

The CCD camera has been charged for five hours, but it doesn't turn on for two reasons. One is battery failure, and the other is charger failure. If there is no test instrument (multimeter), please try to wipe the three contacts of the charger and battery with a cotton swab. You can also find a mobile phone universal charger to charge the battery (charging time is longer), and then try to put the battery in the camera. If the camera can be turned on, put the battery in the Fuji charger to see if it can be recharged. If the indicator light is still off, the charger is faulty.
