It replaces OEM part numbers BH39100, 35H00167-00M, 35H00167-03M, and 35H00167-01M. If your Velocity 4G is shutting down unexpectedly, not holding charge, or failing to power on, this cell replaces the original unit directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVelocity 4G compatibility:\u003c\/strong\u003e\n    All four OEM part numbers listed above share the same 3.7V single-cell Li-ion platform, connector pinout, and BMS handshake profile used across Velocity 4G production runs. The revision codes (00M, 01M, 03M) reflect manufacturing batches, not electrical changes — one cell fits all.\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 Velocity 4G platform and monitored BMS communication. The protection circuit responded correctly to charge termination, over-discharge cutoff, and thermal thresholds throughout testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable any fast-charge mode and run one full discharge-to-charge cycle at standard current. This lets the phone's fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated cell.\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 Velocity 4G after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell has a slightly different internal resistance profile than the aged cell the phone's fuel gauge was trained on. Under peak load — mobile data, screen-on, GPS active simultaneously — the voltage drops faster than the gauge predicts, and the BMS trips the cutoff before the displayed percentage reaches zero. The phone reads 25% but the actual cell voltage has already fallen below the BMS cutoff threshold of around 3.0V under load. One complete slow discharge-charge cycle recalibrates the coulomb counter and eliminates this mismatch. After that cycle, percentage readings and actual cutoff voltage align correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically in the first few days after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Velocity 4G uses a fuel gauge IC that builds its state-of-charge model from discharge history. When a new cell replaces a degraded one, the IC has no valid reference curve for the new cell's capacity and internal resistance — so it interpolates badly, producing percentage jumps of 5–15% in either direction. This is not a fault with the replacement cell. Run two full discharge cycles — drain until the phone shuts off automatically, then charge uninterrupted to 100% — and the gauge IC will rebuild its model. Jumps should resolve by the end of the second cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404311494746,"sku":"BWCS-HTX710XL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404311527514,"sku":"BWCS-HTX710XL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404311560282,"sku":"BWCS-HTX710XL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTX710XL-1.webp?v=1779369680","url":"https:\/\/batteryweb.com\/products\/telstra-velocity-4g-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
