It fits the slim chassis without modification and restores charging from a flat state. OEM cross-references include S13-R2, S13-R2-A, 58-000056, and MC-305070.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKindle Voyage and NM460GZ compatibility:\u003c\/strong\u003e\n    Both share the same 3.8V Li-Polymer cell format, connector pinout, and BMS communication protocol — no adapter or wiring change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the Voyage mainboard and confirmed the BMS accepted the handshake, balanced charge termination triggered correctly at 4.35V, and the device powered fully through discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run the Voyage down to automatic shutoff, then charge uninterrupted to 100% without using the device. This resets the fuel gauge IC against the new cell and corrects the inaccurate percentage reading that typically appears right after installation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Kindle Voyage shuts down at 15–20% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Voyage's fuel gauge IC stores a capacity model calibrated to the old, degraded cell. When a new cell is installed, that stored model no longer matches actual cell voltage behaviour. The result is a voltage cliff — the device reads 15–20% remaining but the fuel gauge triggers low-voltage cutoff because the curve doesn't align. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% rewrites the capacity model and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKindle Voyage showing incorrect battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a fuel gauge drift issue, not a cell defect. The percentage shown on screen is calculated by the fuel gauge IC using a stored profile from the previous battery. A fresh cell has different open-circuit voltage characteristics, so the gauge reads incorrectly until recalibrated. Discharge the Voyage completely until it powers off on its own, then plug in and charge to 100% without interruption — the gauge recalibrates during that single cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425850327130,"sku":"BWCS-ABN460SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425850359898,"sku":"BWCS-ABN460SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425850392666,"sku":"BWCS-ABN460SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABN460SL-1.webp?v=1779929950","url":"https:\/\/batteryweb.com\/products\/amazon-kindle-voyage-replacement-battery-38v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
