Smart door lock power source

The KingSener ZNS-09F is a 5000mAh 7.4V lithium-ion replacement battery designed for compatible smart door lock systems. It serves owners who need a direct swap for a depleted original pack without modifying the device.

5000mAh capacity and 7.4V output

The 5000mAh capacity at 7.4V supplies the energy reserve the lock requires for routine locking cycles and wireless communication. Runtime scales with lock activity; heavy daily use or frequent remote commands will drain the pack faster than light residential traffic.

P- P+ C+ P+ P- pin interface

The pack uses a P- P+ C+ P+ P- connector layout that must match the lock’s internal header exactly. Verifying the pin order before installation avoids misalignment and ensures the battery management circuit communicates correctly with the lock controller.

Questions about this item

Will the ZNS-09F 5000mAh 7.4V battery fit the same connector as my current smart door lock pack?

The pack uses a P- P+ C+ P+ P- pin layout; match that sequence on your existing connector before installing.

How can I confirm the new KingSener ZNS-09F is charging and holding charge correctly?

After installation, the lock should power up immediately and report a full charge state; monitor the first few cycles for consistent voltage.

Does the ZNS-09F box include mounting screws or a wiring harness, or must I order them separately?

Only the 5000mAh 7.4V Li-ion battery is supplied; any screws, cables or adapters required for your lock model must be sourced separately.
