It uses the OEM part number DL-30 and powers the lock's electronic control module, motor drive, and keypad or remote entry functions. Swap it in when the original pack depletes and the lock stops responding to access attempts.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eK380-001 power architecture:\u003c\/strong\u003e\n    The K380-001 draws from a single 12V battery pack to run both the logic board and the drive motor in the same circuit. Splitting those loads across two separate batteries or mismatching voltage will trip the lock's protection logic and prevent the bolt from actuating.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the DL-30 through repeated lock and unlock sequences on the K380-001 and confirmed the BMS accepted the full 12V rail without flagging a low-voltage fault at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting the new battery, test every active access method — keypad, remote, and any enrolled keycards — before closing the door. The K380-001 runs a firmware handshake after power interruption, and some access credentials won't authenticate until that sequence completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning on the K380-001 immediately after a fresh DL-30 install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the lock samples the battery voltage within the first few seconds of power-on, before the alkaline cells have settled under load. Alkaline packs can read below the lock's threshold voltage during that initial inrush from the motor. Remove the battery, wait 10 seconds, and reinsert it — this lets the logic board reinitialise and re-sample at rest voltage. If the warning clears, the battery is fine. If it persists, check the terminal contacts are clean and making full contact, then measure the pack voltage — it should read at or above 12V at rest.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eK380-001 bolt moving slowly or stopping mid-travel after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA sluggish or stalled bolt usually means the drive motor is not getting full voltage at the moment of peak draw. Alkaline cells that have been sitting in storage lose surface charge and sag under the high-current spike the motor needs to start moving the bolt. Check pack voltage under load — if it drops below 10.5V during actuation, the cells are below usable capacity despite reading 12V at rest. Use a fresh DL-30 from sealed stock and confirm the voltage holds above 11V through a full lock-unlock cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360202817626,"sku":"BWCS-SDL300SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360202850394,"sku":"BWCS-SDL300SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360202883162,"sku":"BWCS-SDL300SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDL300SL-1.webp?v=1778610960","url":"https:\/\/batteryweb.com\/products\/locknetics-k380-001-replacement-battery-12v-2300mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
