Mortise Lock Cassette Cavity & AA-Format Clearance
Residential and hotel smart door locks restrict battery thickness to cylindrical 14 mm or 18 mm cassettes. Compare 14500 (14×50 mm) and 18650 (18×65 mm) bare cell envelopes before laying out internal plastic holders.
Quiescent Standby Drain vs Solenoid Inrush Current
Wi-Fi and Zigbee lock boards draw 50–200 µA in sleep mode but demand 1.5 A–3.0 A for 300 ms when driving deadbolt gearmotors or releasing electromagnetic mag-locks.
Float-Charge Cutoff on Alarm Control Panels
Intrusion alarm enclosures switching from sealed lead-acid to 4S LiFePO4 or 3S Li-ion standby packs require verifying float charger output voltage (14.4 V for 4S LFP vs 12.6 V for 3S Li-ion).
Low-Self-Discharge Cell Matching for 12-Month Lock Intervals
Batch-sorted EVE 14500 08E and 18650 26V/33V cells minimize open-circuit voltage drift across 6 to 12 months between USB-C recharge cycles.

Smart Locks, Access Control & Alarm Systems Battery Engineering FAQs
Which cylindrical cell formats fit slim mortise smart door locks?
EVE 14500 08E (3.6V 750mAh) and EVE 14500 06E (3.2V 600mAh LiFePO4) match the 14×50 mm AA footprint for ultra-narrow aluminum door stiles, whereas wider mortise handles accommodate 2S1P or 1S2P 18650 (18×65 mm) cell packs.
Can a 4S LiFePO4 pack replace a 12V 7Ah SLA battery inside an access control power supply box?
Yes, when custom-assembled in a 4S configuration (12.8 V nominal, 14.6 V upper charge limit) and paired with an access-control power supply whose float voltage stays between 13.8 V and 14.4 V.
Why do biometric facial-recognition locks require higher pulse current than keypad locks?
3D structured-light cameras and infrared flood illuminators draw 1.2 A–2.5 A simultaneously with the mortise motor during wake-up, favoring low-impedance 18650 cylindrical cells.
How do I order custom wire harnesses and NTC plugs for alarm backup packs?
Provide your PCB header pitch (such as 2.0 mm PH or 2.54 mm XH), lead length, and compartment L × W × T dimensions through our Custom Battery Pack engineering page.
