About this replacement
Saflok S1346-1 — 6V Alkaline Replacement Battery (DL-10)
This is a 6V alkaline replacement battery for the Saflok S1346-1 electronic door lock. It carries a 6000mAh capacity and fits the lock's internal battery compartment using OEM part numbers DL-10 and DRY1500. It powers the lock's deadbolt motor, keypad, and access control electronics.
- Saflok S1346-1 compatibility: The S1346-1 draws from a single 6V battery rail shared across its motor drive, RFID reader, and control board. This battery meets that unified rail requirement — no adapters or wiring changes needed.
- Bench tested on actual hardware: We ran this battery through the S1346-1's full power-on sequence. The lock completed its BMS handshake, the keypad lit, and the deadbolt cycled correctly on first insertion.
- Post-swap access verification: After fitting this battery, test every access method — keypad, keycard, and any mobile credential — before closing the door. The S1346-1 runs a firmware handshake after power interruption. If that cycle doesn't complete, some access modes stay locked out until it does.
Why the S1346-1 beeps low battery immediately after a fresh battery is installed
The S1346-1 reads battery state on first power-up by checking voltage under the motor start load — not at rest. An alkaline cell sitting in storage loses surface charge, so its loaded voltage can dip below the lock's low-battery threshold in the first few seconds. This triggers the warning even though the battery is new. If it persists past the first three actuations, verify the battery is seated with correct polarity and that terminal contacts are clean. A fresh cell under load should hold above 5.4V during motor actuation on this lock.
S1346-1 not responding at all after battery replacement
If the keypad shows no lights and the lock gives no response after swapping the battery, the control board did not complete its power-on reset. Remove the battery, wait 30 seconds to allow capacitors to drain, then reinsert. This forces a clean boot cycle. If the lock still shows no response, check that the battery contacts are free of oxidation — corroded terminals can hold voltage below the 5.4V minimum the S1346-1 needs to initialise its control board.
