It fits the D14, K8, K10, and K12 series, along with two additional compatible models. The OEM part number is 9018912, cross-referencing 9000163, 9500005, and 5014321A.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD14 and K-series platform compatibility:\u003c\/strong\u003e\n    These Bosch models share the same 6V power rail, physical form factor, and BMS handshake protocol. One cell covers the full range — no adapter or firmware adjustment needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on a D14 unit. The BMS accepted the cell without fault codes, and voltage held steady across the full discharge curve without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install reconnection window:\u003c\/strong\u003e\n    After installing, allow 60 seconds before expecting the device to reconnect. Bosch smart home devices run a mesh network re-join sequence after any power interruption — cutting that window short can trigger a false offline status in the app.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the D14 drains faster after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH cell stored for several months arrives at a suppressed voltage — typically below the device's normal operating range. The D14's power management circuit interprets this as a partially discharged cell and increases polling frequency to compensate. That behaviour pushes drain up sharply in the first 24–48 hours. Run one full charge cycle before drawing conclusions about battery life.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alert showing immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell's resting voltage at delivery is below the alert threshold the hub monitors — common with Ni-MH after extended shelf storage. The device is not faulty; it is reporting accurately based on what it reads at that moment. Place the device in its charger (or charge via the hub if supported) and let it reach a full charge. The alert clears once the cell voltage rises above approximately 6.8V under light load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416144183386,"sku":"BWCS-BSK500SL-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416144216154,"sku":"BWCS-BSK500SL-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416144248922,"sku":"BWCS-BSK500SL-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSK500SL-1.webp?v=1779760467","url":"https:\/\/batteryweb.com\/products\/bosch-d14-replacement-battery-6v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
