It matches the original's physical dimensions at 88.91 × 34.73 × 4.25mm for a direct fit inside the battery bay. Voltage and capacity align with the stock specification — 7.6Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade Apex 2 and Orange HI 4G compatibility:\u003c\/strong\u003e\n    Both devices run the same battery bay geometry, connector pinout, and charge IC handshake. One cell covers both variants without adapter or modification.\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 a Blade Apex 2 unit. The BMS accepted the charge controller handshake cleanly, held voltage through screen-on and modem load, and tripped no thermal or overcurrent faults across three full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging if your device supports it, then run one complete discharge down to auto-shutdown followed by a full charge. This lets the coulomb counter map the new cell's discharge curve before resuming normal charge rates.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Blade Apex 2 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe phone's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, the IC is still referencing the old curve — so percentage readings can be off by 10–20% in either direction. The fix is one full discharge-to-shutdown cycle followed by an uninterrupted charge to 100%. After that cycle, the coulomb counter resets its baseline against the new cell's actual capacity and the percentage display stabilises.\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 phone's display or modem draws a brief high-current spike and the cell cannot sustain voltage through it — the battery hits a voltage cliff before the percentage gauge catches up. It is not a faulty cell; it is the fuel gauge IC firing a low-voltage cutoff while still showing 20–30% because calibration is incomplete. Run one full discharge cycle as described above. If shutdowns persist after two full cycles, check that the battery connector is fully seated — an intermittent contact creates the same voltage-sag symptom.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404236456026,"sku":"BWCS-ZTQ505SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404236488794,"sku":"BWCS-ZTQ505SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404236521562,"sku":"BWCS-ZTQ505SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTQ505SL-1.webp?v=1779369465","url":"https:\/\/batteryweb.com\/products\/original-blade-apex-2-replacement-battery-38v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
