It matches the original's dimensions (88.60 × 66.50 × 4.00mm) and BMS handshake requirements so the phone powers on and communicates charge state normally. Capacity is rated at 14.25Wh — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTA-1322 \/ TA-1323 \/ TA-1329 \/ V730 compatibility:\u003c\/strong\u003e\n    These four models share the same connector pinout, cell footprint, and BMS communication protocol. Swapping between any of them uses the same P104BMA006000 form factor — the fuel gauge IC on each board reads the same cell chemistry and reports correctly without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a TA-1322 board through charge, discharge, and a modem-load stress pass. The BMS held voltage above the cutoff threshold under screen-plus-LTE load, and the charge IC accepted the full 3700mAh without triggering an early termination flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's actual discharge curve before high-current charging pushes current into an uncalibrated baseline.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Nokia V730 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on these Nokia boards uses a stored discharge curve from the previous cell to estimate remaining capacity. When you install a new cell, that stored curve no longer matches the new chemistry's actual voltage-to-capacity relationship. The IC keeps reporting against the old data until it completes at least one full discharge-charge cycle to recalibrate. Run the phone down to auto-shutdown, charge uninterrupted to 100%, and the percentage readout will stabilise at that point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the TA-1322 after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet recalibrated and the cell hits a voltage cliff under modem or display load before the reported percentage reaches zero. The screen load plus active LTE draws enough current to sag cell voltage below the BMS cutoff threshold — the phone shuts down even though the gauge still shows charge remaining. It is not a faulty cell. Complete one full uninterrupted discharge to shutdown, then charge to 100% without interruption. After that cycle, the coulomb counter resets to the correct baseline and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391869386842,"sku":"BWCS-NKV700SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391869419610,"sku":"BWCS-NKV700SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391869452378,"sku":"BWCS-NKV700SL-3","price":40.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKV700SL-1.webp?v=1779142430","url":"https:\/\/batteryweb.com\/products\/nokia-ta-1322-replacement-battery-385v-3700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
