It slots into the handset battery compartment and powers the wireless transmitter and receiver circuitry. No OEM part number is published for this cell, but voltage and physical dimensions match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAmerican Telecom 2250 fit:\u003c\/strong\u003e\n    The 2250 handset runs a single 2.4V NiMH cell at 700mAh. That voltage rail feeds both the DECT transmitter and the standby logic board. A lower-voltage or mismatched cell triggers a low-battery alert immediately after the base releases charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence on a NiMH analyser. The BMS accepted charge without fault from the first cycle, and the cell held voltage above 2.2V through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\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 ship partially discharged, and a slow initial charge lets each cell reach rated capacity. Cutting that first charge short locks in a lower capacity ceiling across all future cycles.\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 no charge light on a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells lose voltage during storage. If the cell voltage drops low enough, the base station charge circuit may not recognise it as a valid battery and will show no charge light or a fault indicator. Most 2250 base chargers use a delta-V detection method — the charger looks for a small voltage rise to confirm a cell is present and accepting charge. A deeply discharged cell below around 2.0V may not trigger that rise quickly enough. To recover, leave the handset seated in the base for at least 30 minutes — the trickle circuit will usually bring the cell up to a voltage the main charge cycle can detect.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected for the first few cycles\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew NiMH cells do not deliver full rated capacity immediately. The crystal structure inside the cell needs three to five full charge-discharge cycles before it reaches 700mAh. During those early cycles, talk time will be noticeably shorter than the original battery at its best. Run the handset down until it signals low battery, then seat it for a full 16-hour charge — repeat this three to five times. By cycle five, capacity should stabilise at or near the rated 700mAh.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339911495770,"sku":"BWCS-PTG103CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339911528538,"sku":"BWCS-PTG103CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339911561306,"sku":"BWCS-PTG103CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PTG103CL-1.webp?v=1778366944","url":"https:\/\/batteryweb.com\/products\/american-telecom-2250-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
