Looking for Custom Battery Pack Replacements?

At National Battery Supply, we manufacture replacement battery packs for electronic door locks and other access systems to match your specifications. 

Whether you need a standard alkaline pack or a high-performance lithium or rechargeable NiMH build, we have a solution that fits.

Electronic door locks and access control systems are critical for security in hotels, hospitals, commercial buildings, government facilities, and residential complexes. When their battery packs run low, access can be disrupted – causing downtime, security risks, and frustrated tenants.

• AA, AAA, C, and D Cell Packs – Standard alkaline builds for common lock systems.
• Lithium Battery Packs – Longer lifespan, ideal for extreme temperatures.
• Rechargeable NiMH Packs – Perfect for high-use environments where recharging is an option.
• Custom Voltage Packs – From 3V to 24V, designed to your lock’s power needs.
• OEM-Specific Connectors & Wiring – Matched to your existing system or upgraded for easier installation.
