Exit signs often use rechargeable batteries to maintain functionality during power outages. Over time, these batteries degrade and will need to be replaced to ensure the sign remains illuminated when necessary.

Signs That You Need to Change the Battery

Before diving into how to change exit sign battery, it's essential to recognize the signs that indicate a battery replacement is needed:

• The exit sign is flickering or dim.
• When the power goes out, the sign does not illuminate at all.
• The battery or exit sign emits a beeping sound.
• A visual inspection shows signs of corrosion or leaks.

Tools Required for Battery Replacement

To successfully change the battery, gather the following tools and materials:

• Screwdriver (typically Phillips or flat-head, depending on your sign)
• Replacement battery (check the manufacturer specifications)
• Safety goggles (for eye protection)
• Work gloves (to keep hands safe)
