When properly maintained, your Safemark safe will provide many years of secure service. Our hotel safes operate on 4 AA alkaline batteries that should be changed every other year. Hotel safes found in extreme environments may need battery replacement every year.

To check the battery level, press the LOCK button once while the safe door is open. The keypad display will show batt-L if the batteries are low and batt-H when the batteries are charged.

 

A recent Consumer Reports test on AA alkaline batteries ranked Duracell Advanced Ultra as the overall leader and the Kirkland Signature battery from Costco as the best value. Beware of batteries that claim to be HEAVY DUTY but do not list alkaline on their label.

 

Please consider the environment when disposing of used batteries.
