It slots into the same battery compartment as the original cell and restores cordless operation. Dimensions are 68.00 × 16.30 × 13.20 mm — confirm these against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLBB 6213\/01, 6214\/23C, and 6262\/00 compatibility:\u003c\/strong\u003e\n    These three headsets share the same battery form factor, voltage rail, and connector orientation. The DECT radio module and audio circuit both draw from the same cell, so voltage tolerance across the platform is tight — Ni-MH chemistry at 3.6V nominal matches the original spec exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on compatible Bosch base station hardware. The BMS handshake completed without error on the base unit, and the charge indicator moved through its normal sequence without stalling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for DECT headsets:\u003c\/strong\u003e\n    Place the headset in the base station and allow a full uninterrupted charge cycle before making any calls. The base station logs the new cell during this cycle — skipping it causes the talk-time estimate on the base display to read inaccurately for days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not recognising the new pack after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LBB base station uses a handshake sequence to identify a connected cell before it begins a charge cycle. If the new battery arrived at storage voltage — typically around 3.2–3.4V — the base may flag a charge error or show no activity on the indicator. Seat the headset firmly in the cradle and leave it for at least 15 minutes before assuming a fault. If the indicator still shows an error, remove and reseat the headset once — this resets the handshake attempt.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call on a freshly charged battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe combined draw of the DECT radio transmitter and audio circuit creates short current spikes that exceed the steady-state draw significantly. A new Ni-MH cell that has not yet completed its first full conditioning cycle has higher internal resistance, which causes voltage to sag briefly under these spikes. The headset's protection circuit reads that sag as low battery and cuts the connection. Run three to five full charge-discharge cycles through the base station — internal resistance drops with each cycle and the cutouts stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428131799130,"sku":"BWCS-BCH621SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428131831898,"sku":"BWCS-BCH621SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428131864666,"sku":"BWCS-BCH621SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCH621SL-1.webp?v=1779934222","url":"https:\/\/batteryweb.com\/products\/bosch-lbb-621301-replacement-battery-36v-500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
