It replaces the original cell pack when the unit stops holding a charge. Voltage and cell count match the original, so no modifications are needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLD78R parent unit fit:\u003c\/strong\u003e\n    The Baby Talk LD78R uses a compact Ni-MH pack at 4.8V to power its radio receiver, two-way audio circuit, and display backlight simultaneously. This replacement matches those rails exactly — same voltage, same physical footprint at 44 × 41 × 10.50mm.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge cycle and confirmed the BMS accepted charge without interruption. Two-way talk and the audio alert circuit both triggered correctly at operating voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pairing after install:\u003c\/strong\u003e\n    After fitting this battery, the parent unit may have lost its wireless link to the transmitter unit. Power both units off, then hold the pairing button on the transmitter until the parent unit confirms the connection. This is standard behaviour after a full power interruption on the LD78R.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit not connecting to the camera unit after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the parent unit drops to zero volts — which happens during a battery replacement — it loses the pairing data stored in volatile memory. The transmitter unit is still broadcasting, but the parent unit no longer recognises the channel. To fix this, power both units on, then initiate a fresh pairing sequence from the transmitter side. Once the parent unit displays the signal indicator, the link is restored and audio will pass through normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit battery draining overnight with screen on\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRunning the LD78R parent unit with the display backlight active through the night puts a sustained draw on a 700mAh pack — the screen, radio receiver, and speaker circuit all pull current simultaneously. This is not a fault with the battery; it reflects how much the original pack had degraded before you replaced it. Enable the screen timeout setting in the parent unit menu so the display cuts after a short idle period. That alone significantly reduces overnight drain on a fresh 700mAh cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315075055706,"sku":"BWCS-SF2170MB-1","price":14.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315075088474,"sku":"BWCS-SF2170MB-2","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315075121242,"sku":"BWCS-SF2170MB-3","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SF2170MB-1.webp?v=1777949713","url":"https:\/\/batteryweb.com\/products\/lindam-baby-talk-ld78r-replacement-battery-48v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
