It fits the GT-P5210, GT-P5200, GT-P5220, and Galaxy Tab 3 10.1. The T4500E cell slots into the original battery bay using the same connector and dimension footprint as the factory unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-P5200 \/ GT-P5210 \/ GT-P5220 fit:\u003c\/strong\u003e\n    These three variants share the same 3.8V power rail, battery bay dimensions, and BMS connector pinout. Samsung used the same T4500E cell across all three, so one SKU 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 on a GT-P5210 and monitored BMS communication through three full charge cycles. The protection circuit handled charge cutoff at 4.35V and discharged cleanly to the low-voltage cutoff without tripping prematurely or logging errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge it uninterrupted to 100% without using the device. This forces the fuel gauge IC to recalibrate against the new cell and clears the inaccurate percentage readings that typically appear 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\"\u003eWhy the GT-P5210 shuts down at 15–25% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy Tab 10.1 drives a large IPS display and simultaneous WiFi at the same time. That combined draw creates a voltage dip the old cell can no longer sustain at lower states of charge. The BMS reads this dip as a cutoff condition and shuts the device down even though the percentage gauge still shows capacity remaining. A new cell with full capacity holds voltage under that combined load, and the shutdowns stop. After installing, do the full recalibration cycle described above so the fuel gauge reflects actual cell capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after a battery swap on the Galaxy Tab 3 10.1\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's charge IC negotiates the fast-charge rate during the first accepted charge cycle after a new cell is recognised. If the tablet is used heavily or disconnected during that first session, the negotiation is incomplete and the device defaults to standard charge rates. Plug the tablet into the original Samsung charger and leave it connected from flat to 100% without interruption. After that single cycle, the charge IC registers the new cell and fast charging becomes available again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426069446746,"sku":"BWCS-SGP520SL-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426069479514,"sku":"BWCS-SGP520SL-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426069512282,"sku":"BWCS-SGP520SL-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGP520SL-1.webp?v=1779930340","url":"https:\/\/batteryweb.com\/products\/samsung-gt-p5210-replacement-battery-38v-6800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
