It also fits the DM009SH and SH8158 variants. The OEM part numbers are SHBDL1 and EA-BL28.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGalapagos 003SH and variant compatibility:\u003c\/strong\u003e\n    The 003SH, DM009SH, and SH8158 all share the same 3.7V battery rail, connector pinout, and BMS handshake protocol. One cell fits the full group because Sharp used a common battery platform across this hardware generation.\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 003SH platform. The BMS accepted the cell without triggering fault flags, and the charge IC completed a full constant-current\/constant-voltage cycle to 4.2V with no thermal events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable any fast-charge mode and run one complete discharge-to-charge cycle. The fuel gauge IC on the 003SH is calibrated to the old cell's discharge curve. One full cycle lets it re-map against the new cell before drawing high current into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Galapagos 003SH after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 003SH's modem and display draw a short burst of current that can pull the cell voltage below the BMS cutoff threshold, even when the fuel gauge still shows charge remaining. A fresh cell with a slightly different internal resistance curve will hit that voltage cliff at a different state-of-charge than the fuel gauge expects. This causes abrupt shutdowns that look like a defective battery but are actually a calibration mismatch. Run two full discharge-charge cycles and the fuel gauge IC will track the new cell's curve accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting an incorrect battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe coulomb counter in the 003SH retains learned data from the old cell and applies it to the new one immediately on boot. Because the new cell's capacity and discharge curve differ from the worn cell, the percentage reading drifts — often reading 100% too quickly or dropping steeply in the lower range. This is a fuel gauge IC recalibration issue, not a fault with the replacement cell. Drain the phone fully until it shuts down, then charge uninterrupted to 100% to force a fresh calibration pass.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405091045466,"sku":"BWCS-SH003SL-1","price":28.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405091078234,"sku":"BWCS-SH003SL-2","price":32.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405091111002,"sku":"BWCS-SH003SL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SH003SL-1.webp?v=1779369970","url":"https:\/\/batteryweb.com\/products\/sharp-galapagos-003sh-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
