It fits the 32102, 32103, 32108, and 32109 models, along with eight additional Levana baby monitor variants. When the original cell degrades and the parent unit dies mid-session, this is the direct replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e32100-series parent unit fit:\u003c\/strong\u003e\n    These Levana models share the same parent unit housing, connector orientation, and 3.7V power rail. The WLW523450 ERA cell slots in without modification and the internal protection circuit matches the original charge termination voltage.\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. The BMS held charge termination at 4.2V and triggered low-voltage cutoff cleanly before the cell dropped below safe thresholds — no erratic shutdowns during the draw cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap wireless re-pair:\u003c\/strong\u003e\n    Levana parent units drop their camera link when the battery goes flat or is physically removed. After fitting this battery and powering on, run the manual re-pair sequence from the parent unit menu before expecting live video — the monitor does not reconnect automatically.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit range dropping after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Levana parent unit's radio transmitter draws from the same 3.7V cell that runs the screen and audio. A partially charged or degraded cell causes the radio to operate at reduced power, which cuts effective range noticeably. This shows up most in two-storey homes where the signal already runs near the limit. Charge the replacement battery to 4.2V before first use and run a full charge cycle — range restores once the cell is at full capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit screen stays blank after fitting the new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA blank screen on first power-up usually means the replacement cell shipped at storage voltage — typically around 3.6V — which is below the Levana parent unit's startup threshold. The unit draws a short high-current spike to initialise the display and radio, and a low-charge cell can't sustain it. Connect the parent unit to its charger for at least 30 minutes before pressing power. Once the cell climbs above 3.75V, the unit will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315071844442,"sku":"BWCS-PHD600MB-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315071877210,"sku":"BWCS-PHD600MB-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315071909978,"sku":"BWCS-PHD600MB-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHD600MB-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/levana-32102-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
