It slots into the handset battery compartment and powers the DECT transmitter, speaker, and display. If your handset no longer holds a charge or cuts out during calls, this battery is the direct fix.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared battery across Nomad cordless handset range:\u003c\/strong\u003e\n    These models share the same 3.6V cell configuration, connector pinout, and physical footprint, which is why one battery covers the full range. The BMS threshold in each handset accepts the same charge profile, so no firmware or hardware changes are needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on Nomad handset hardware. The BMS accepted the NiMH charge curve without error, and the cell voltage held stable across RF transmit events that typically expose weak cells.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless phones need a slow initial charge to reach rated capacity — skipping this shortens talk time on early cycles.\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 a battery swap on Nomad handsets\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells that haven't completed conditioning cycles will sag in voltage when the DECT transmitter fires at full power. The RF transmit circuit draws a brief high-current spike, and an undercharged NiMH pack can't sustain the voltage — the handset reduces transmit power to compensate. This shows up as reduced range or choppy audio near the edge of the coverage area. Run three full charge-discharge cycles and the voltage sag typically disappears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating with new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries stored in a warehouse often drop to 2.8V or lower before they reach the customer. Some Nomad base stations have a charge acceptance threshold and won't begin charging if the cell voltage is too far below nominal. The fix is to briefly connect the handset to a compatible external NiMH charger to bring the pack above 3.2V, then return it to the base. Once the base detects a voltage in the acceptable window, the charge indicator activates normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340023332954,"sku":"BWCS-CPB1024-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340023365722,"sku":"BWCS-CPB1024-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340023398490,"sku":"BWCS-CPB1024-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB1024-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/nomad-1231-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
