It replaces the original pack that powers the handheld receiver, letting you monitor your baby without keeping the unit permanently plugged in. Fit the battery, charge it fully, and the parent unit is ready to use untethered again.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAT22R parent unit fit:\u003c\/strong\u003e\n    The AT22R parent unit uses a compact 4.8V Ni-MH cell pack to match the receiver's radio and audio circuitry voltage rail. This battery meets that spec exactly — same cell count, same connector footprint at 57.71 x 50.79 x 14.58mm.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the AT22R platform. The battery accepted a full charge without thermal event and held voltage within the range required for stable audio and radio operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pair the units after fitting:\u003c\/strong\u003e\n    Completely removing the old battery interrupts the AT22R parent unit's stored link with the nursery transmitter. Once the new battery is in and charged, run the pairing sequence from the parent unit menu before expecting audio from the nursery unit.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit battery draining overnight on the AT22R\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRunning the AT22R parent unit all night with the screen active puts sustained current draw on the 2000mAh pack. The display backlight and radio receiver together pull more current than the battery was sized to carry indefinitely. Enable the screen timeout in the parent unit settings — the audio alert stays live while the screen sleeps. This alone significantly reduces overnight drain without losing any monitoring function.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange noticeably shorter after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AT22R's radio transmitter draws from the battery voltage directly, and Ni-MH cells fresh off a first charge don't always reach their rated voltage immediately. A low starting voltage means the radio module runs below its intended power level, which cuts usable range. Charge the new battery for a full uninterrupted cycle — typically to 4.8V measured at the pack terminals — before judging the range. Most range complaints after a swap resolve after the first or second full charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315073351770,"sku":"BWCS-PHT920MB-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315073384538,"sku":"BWCS-PHT920MB-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315073417306,"sku":"BWCS-PHT920MB-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHT920MB-1.webp?v=1777949712","url":"https:\/\/batteryweb.com\/products\/audiofox-at22r-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
