Important Battery Information
Batteries are perishable items. For best results, it is recommended that the battery receive an initial charge within the first 18 months of the manufacture date of the fixture. The manufacturing date can be found on the outside of the unit packaging and on the UL label as part of the Date Code/Series. Note: The first two digits in the date code will represent the year, and the second two digits will represent the month. Batteries beyond the initial charge recommendation time frame can often be returned to full capacity by fully charging the battery shortly after installation. If the battery will not fully charge after the initial charge, replacing the battery with a fresh battery will resolve the issue.
