It matches OEM part number 056080CN55 and fits the OP0118-13 configuration. When the original cell degrades and the tablet no longer holds a charge, this replaces it directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMeep and Meep X2 compatibility:\u003c\/strong\u003e\n    Both tablets share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol — one battery covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Meep X2 unit. The BMS accepted the cell without fault codes, and the charge IC completed a full cycle to 4.2V without thermal events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap fuel gauge reset:\u003c\/strong\u003e\n    After installing this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. The fuel gauge IC on the Meep calibrates against the new cell during this first full cycle — skipping it leaves the percentage display drifting against the actual cell state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Meep shuts down at 15–20% battery remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Meep's fuel gauge IC stores a charge curve mapped to the original cell. When that cell ages and its internal resistance rises, the IC's stored curve no longer matches real-world voltage behaviour. Under combined load — backlit display, active Wi-Fi, and audio — the cell voltage drops sharply, hitting the low-voltage cutoff before the percentage readout reaches zero. Replacing the battery solves the hardware side, but the IC still needs one full discharge-to-shutoff cycle to remap the curve to the new cell. After that cycle, shutdowns at 15–20% stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or stuck after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a fuel gauge drift issue, not a fault with the new cell. The Meep uses a Coulomb-counting IC that was last calibrated to the old, degraded battery — it has no reference data for the new cell's capacity. Until it runs one complete cycle, the percentage can read 40% and jump to 15% within minutes, or stick at a fixed value for long stretches. Run the tablet fully to automatic shutoff on battery, then plug in and charge without interruption to 100%. One complete cycle resets the calibration and the percentage display stabilises at 3.7V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425833812058,"sku":"BWCS-RSX200SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425833844826,"sku":"BWCS-RSX200SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425833877594,"sku":"BWCS-RSX200SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RSX200SL-1.webp?v=1779929930","url":"https:\/\/batteryweb.com\/products\/oregon-scientific-meep-replacement-battery-37v-2900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
