It matches the original cell format — 117.00 x 53.25 x 3.80mm — so it sits flush in the battery bay without modification. Swap it in when the original cell no longer holds a charge or the tablet won't power on past the boot screen.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePBSKD12, PBKRWM5410, and 7\" Pad compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and 3.7V power rail, so one cell covers the full group. The charge IC communicates identically across these variants.\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 the PBSKD12 platform. The BMS accepted the charge handshake without fault flags, and the protection circuit responded correctly to over-discharge cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge it uninterrupted to 100% before using it again. This single full cycle lets the fuel gauge IC calibrate against the new cell and clears the inaccurate percentage readings that appear right after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePBS KIDS PBSKD12 shutting down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the display backlight and WiFi radio pull current simultaneously, causing a brief voltage sag that the fuel gauge reads as a depleted cell. The old battery's charge curve was mapped to a degraded cell, so the OS shuts down well before the new cell is actually empty. One full discharge-to-shutoff followed by a complete uninterrupted charge corrects the calibration. After that cycle, the tablet should run down to single digits before cutting off.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery swap on the PBSKD12\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome units won't negotiate fast charge on the first cycle after a new battery is installed. The charge IC needs at least one complete accepted charge cycle before it re-enables higher current draw from a compatible adapter. Use the original PBS KIDS charger, let the tablet charge to 100% without unplugging early, then check again on the next session. If fast charge still doesn't appear, confirm the adapter output rating — the tablet requires the correct voltage and current spec to trigger the faster charge mode.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425831944282,"sku":"BWCS-PBS120SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425831977050,"sku":"BWCS-PBS120SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425832009818,"sku":"BWCS-PBS120SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PBS120SL-1.webp?v=1779929930","url":"https:\/\/batteryweb.com\/products\/pbs-kids-pbskd12-replacement-battery-37v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
