It slots into the handset battery compartment and restores power to the handset for standard talk and standby use. Voltage and cell chemistry match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e27910 and E1112 series handsets:\u003c\/strong\u003e\n    These models share a common 3.6V single-cell NiMH rail and use the same physical form factor — 45.90 x 31.20 x 10.70mm. The base station charging circuit expects NiMH chemistry; swapping to a different chemistry triggers a charge fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a cordless phone test rig. The NiMH cells accepted the trickle charge from the base station without thermal runaway, and the BMS held voltage within the expected window across all cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on NiMH cordless packs:\u003c\/strong\u003e\n    Place the handset in the base immediately after installing and leave it for a full 16 hours before first use. NiMH cordless batteries ship partially discharged and need one slow charge cycle to begin reaching rated capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after fitting a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets ramp transmit power based on available voltage. A freshly installed NiMH pack that hasn't completed its first full conditioning cycle will sag under the RF load draw. This sag looks identical to a weak battery to the handset's power management circuit. The fix is straightforward — run two to three full charge-discharge cycles before judging range performance. After conditioning, transmit voltage holds steady and range returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charge error after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH packs lose charge during storage, and some Lucent base stations won't initiate a charge cycle if the incoming cell voltage reads below the acceptance threshold — typically under 3.0V. The base interprets this as a bad or absent battery and lights an error indicator instead of charging. Remove the handset, wait 10 seconds, reseat it firmly, and leave it undisturbed for at least 30 minutes. If the error clears, the base has detected enough voltage to begin the trickle charge phase.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340017172570,"sku":"BWCS-CPB8011-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340017205338,"sku":"BWCS-CPB8011-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340017238106,"sku":"BWCS-CPB8011-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB8011-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/lucent-27910-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
