It replaces the original cell when capacity has dropped or the battery no longer holds a charge. Dimensions are 87.38 × 62.94 × 5.66mm — confirm fitment against your existing cell before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePower Five and Power Five Pro compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell fits both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Power Five platform. The BMS accepted charge normally, protection circuits tripped correctly at low-voltage cutoff, and the fuel gauge IC tracked state-of-charge without error after a calibration cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge calibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. The fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skipping this step can cause the OS to report inaccurate percentages for the first several days of use.\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 Highscreen Power Five after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter replacing the battery, the Power Five may shut down abruptly while the OS still shows 20–30% remaining. This happens because the fuel gauge IC is still using the old cell's discharge curve — it does not yet know where the new cell's voltage cliff sits. Under modem or display load, the cell voltage drops sharply at that threshold, and the protection circuit triggers a hard cutoff before the OS can react. One full discharge-to-charge cycle without fast charging lets the coulomb counter remap to the new cell and pushes the reported cutoff to the correct level.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Power Five units will not negotiate fast charging on the first cycle with a new cell — the charge IC defaults to standard 5V\/1A until it has completed one baseline charge session with the new BMS. This is a handshake behaviour, not a fault with the battery or the charger. Charge the phone fully once using the standard charger, then reboot. Fast charging will re-engage on the next session once the charge IC has logged an initial full-cycle profile for the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392064979034,"sku":"BWCS-HAR120SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392065011802,"sku":"BWCS-HAR120SL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392065044570,"sku":"BWCS-HAR120SL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAR120SL-1.webp?v=1779143561","url":"https:\/\/batteryweb.com\/products\/highscreen-power-five-replacement-battery-38v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
