About the back-up battery

The SL-5500 has a specified built-in rechargeable back-up battery which prevents the memory contents from being erased when you replace the battery.

•The rechargeable back-up battery will be charged to its full capacity in 30 hours under normal use in the following instances:

–When the AC adapter is connected;

–When the fully charged operating battery (EA-BL06) is inserted.

•The rechargeable back-up battery will be exhausted if you leave an already exhausted operating battery in the SL-5500 for more than a day, or when you replace the operating battery.

•The rechargeable back-up battery (when fully charged) keeps data stored in the SL-5500 for approximately 5 minutes when the operating battery is not inserted.
