Direct replacement for smart door locks

The KingSener ZNS-09 is a 5000mAh 7.4V Li-ion battery built to match the original dimensions and pin layout of compatible smart door locks. It arrives new and ready to install without modification. Buyers needing a different voltage or a higher capacity pack should look elsewhere.

Capacity and daily headroom

Rated at 5000mAh and 7.4V the cell delivers the full design capacity with no inflated figures. Normal lock operation including keypad illumination and motor actuation is supported through extended cycles. The pack will eventually deplete under continuous heavy use or if left uncharged beyond the recommended 80% monthly maintenance threshold.

Thermal behaviour and power draw

Standard Li-ion chemistry runs cool during the brief current pulses a door lock demands. No active cooling is required and the pack produces no audible noise in service. Storage in hot or humid environments accelerates ageing so the supplier advises keeping the battery in moderate conditions and avoiding prolonged adapter connection while the lock is operating.

Questions about this item

Will the ZNS-09 7.4V 5000mAh battery fit the same compartment as my original smart lock battery?

The battery is built to the same physical size as the original unit, so it fits the existing compartment without modification.

How can I verify the ZNS-09 is delivering its rated 5000mAh capacity after installation?

Fully charge and discharge the pack from low current two or three times; the full-charge capacity will then match or exceed the design rating.

Does the ZNS-09 package include a charger or only the battery itself?

The product is supplied as a standalone battery; a compatible charger must be purchased separately.
