Capacity is 7700mAh (28.49Wh), matching the factory specification. Fit models share the same connector, cell footprint, and BMS handshake requirements.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP2450 \/ Loki \/ Shield 2 platform fit:\u003c\/strong\u003e\n    These models run the same power rail and use an identical connector pinout. The BMS on each expects the same charge termination voltage and protection thresholds, so one cell covers all three 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 the P2450 charge IC and confirmed the BMS accepted the new cell, completed a full charge cycle, and engaged both over-current and over-temperature cutoff at correct thresholds during high-draw load testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge calibration after install:\u003c\/strong\u003e\n    After fitting this cell, run one complete wireless play session to automatic low-battery cutoff before recharging. The Shield's fuel gauge IC sets its empty reference point against the first full discharge cycle — skipping this step causes the percentage display to read inaccurately for weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Shield P2450 fuel gauge jumps or reads wrong after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P2450 uses a coulomb-counting fuel gauge IC that builds its discharge model against the cell it first calibrated on. When a new cell goes in, the IC still references the old cell's internal resistance curve, so percentage readings can jump, stall, or drop suddenly. This is not a faulty battery — it is a recalibration lag. One full discharge cycle from 100% to automatic cutoff resets the reference curve. After that cycle the gauge tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShield console shows charging but percentage barely moves in the first session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Shield's charge IC applies a conservative current limit when it detects a new cell — this is a built-in protection behaviour, not a fault with the replacement. The controller interprets the unfamiliar internal resistance profile as a flag to throttle input current. Charge rate normalises after one complete charge-discharge cycle. If the percentage still stalls after two full cycles, confirm the charge port connector is fully seated and check for 5V input at the port.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377539285082,"sku":"BWCS-NSP245SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377539317850,"sku":"BWCS-NSP245SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377539350618,"sku":"BWCS-NSP245SL-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSP245SL-1.webp?v=1778767243","url":"https:\/\/batteryweb.com\/products\/nvidia-handheld-p2450-replacement-battery-37v-7700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
