It replaces the original TBW5931 battery when the existing cell no longer holds a charge or shuts the phone down unexpectedly. Capacity is 5.92Wh — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOmega Q cell fitment:\u003c\/strong\u003e\n    The Omega Q uses a fixed battery bay with dimensions 60.48 × 56.85 × 4.50 mm. This cell matches that footprint exactly, so the connector seats without force and the rear cover closes flush.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the TBW5931 through charge and discharge on a test rig monitoring BMS cutoff thresholds. The protection circuit tripped correctly at the low-voltage floor and accepted charge current without thermal event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging runs 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\"\u003eWhy the Omega Q reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Omega Q's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry. The gauge reads voltage and translates it to a percentage using old data — so it reports numbers that are off by 10–20%. One full discharge to automatic shutdown followed by a complete charge resets the coulomb counter and rebuilds an accurate curve. After that single cycle, percentage readouts stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops sharply under load — the modem transmitting or the screen at full brightness pulls enough current to push cell voltage below the BMS protection threshold even though the gauge still shows charge remaining. A fresh cell with an uncalibrated fuel gauge is the most common cause. Run one full discharge cycle without fast charging to let the gauge recalibrate its voltage-to-capacity mapping. If shutdowns continue after two full cycles, check that the connector is fully seated — a loose contact raises internal resistance and accelerates the voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404257362010,"sku":"BWCS-KTU860SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404257394778,"sku":"BWCS-KTU860SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404257427546,"sku":"BWCS-KTU860SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KTU860SL-1.webp?v=1779369512","url":"https:\/\/batteryweb.com\/products\/highscreen-omega-q-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
