It restores power to the parent unit so you can monitor your baby and use two-way audio without the unit being tethered to the wall. Capacity is 3000mAh (11.1Wh) — matched to the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAinanny parent unit fit:\u003c\/strong\u003e\n    The Ainanny parent unit uses a flat lithium-polymer cell in a compact bay — 64.00 x 49.80 x 6.50mm. This replacement matches that footprint, voltage rail, and connector orientation so the unit closes and seats correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the parent unit platform and confirmed the BMS accepted the charge profile without triggering a fault state. Screen, speaker, and wireless transmitter all drew current within expected parameters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eAfter-swap re-pair step:\u003c\/strong\u003e\n    When the parent unit loses power completely — as it does during a battery swap — it drops its wireless link to the camera unit. After fitting the new battery, re-pair the parent unit with the camera following the pairing sequence in the Ainanny manual before relying on the monitor.\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 with screen active\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNight-time use is the hardest draw cycle for the Ainanny parent unit. The screen stays on, the wireless receiver runs continuously, and the speaker stays armed for audio alerts — all at once. That sustained load pulls the 3000mAh cell down faster than short daytime sessions. Enabling the screen timeout in the unit's display settings cuts the biggest single current draw and extends each charge cycle noticeably.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ainanny parent unit's wireless radio operates at reduced power when cell voltage is low — even a partially charged new battery can cause shorter range right after fitting. This is not a fault with the replacement cell. Charge the parent unit fully before testing range — the radio reaches its rated output only when cell voltage is at or above 3.7V under load. If range remains short after a full charge, the issue is environmental interference, not the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315057459290,"sku":"BWCS-BYT200SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315057492058,"sku":"BWCS-BYT200SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315057524826,"sku":"BWCS-BYT200SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BYT200SL-1.webp?v=1777949547","url":"https:\/\/batteryweb.com\/products\/arenti-ainanny-replacement-battery-37v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
