It fits the LBB4540\/04 and LBB4540\/08 variants and shares the same cell format as OEM part NL-4827HG-10. Capacity is 4.32Wh — matching the original specification from Bosch.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLBB4540 series compatibility:\u003c\/strong\u003e\n    The LBB4540\/04, LBB4540\/08, and Integrus Pocket all run the same 2.4V dual-cell Ni-MH pack on a shared connector and charge circuit. The base station charges via constant-voltage trickle after peak detection — this pack triggers that cutoff correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Integrus base station dock and confirmed the charge termination signal fires at the correct delta-V peak. The BMS logged the new cell without error flags on both the LBB4540\/04 and LBB4540\/08 units we ran.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station conditioning:\u003c\/strong\u003e\n    Place the headset in the base station for a complete charge cycle before taking any calls. DECT headsets use the base charge cycle to calibrate the talk-time estimate — skipping this step causes the indicator to read inaccurately for the first several uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing full charge but headset cuts off after short use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage — typically around 1.0V per cell — not at full charge. If the base station reads this as a topped-up pack and ends the charge cycle early, the headset runs off a partially charged cell. The fix is to dock the headset immediately on arrival and allow a full uninterrupted charge before use. If the base still shows full charge but the headset cuts out, remove the pack, reinsert it, and redock — this forces the charge controller to re-read the cell voltage from scratch.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-call on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Integrus Pocket draws current simultaneously from the audio amplifier and the DECT radio transmitter. Under that combined load, a partially conditioned Ni-MH cell can sag below the headset's low-voltage cutoff threshold, triggering a shutdown even when the charge indicator still shows capacity. This is not a faulty battery — it is a conditioning issue. After three to five full charge-discharge cycles, the cell reaches rated capacity and the voltage sag under load reduces significantly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428141858906,"sku":"BWCS-BCH454SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428141891674,"sku":"BWCS-BCH454SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428141924442,"sku":"BWCS-BCH454SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCH454SL_1.webp?v=1779934222","url":"https:\/\/batteryweb.com\/products\/bosch-integrus-pocket-replacement-battery-24v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
