It slots into the standard battery bay and connects to the device's charge IC and fuel gauge circuit. No OEM part number is listed for this model — verify fit against the dimensions: 72.00 × 56.90 × 4.50mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB2000 Prime fit:\u003c\/strong\u003e\n    The B2000 Prime runs a single-cell 3.7V rail with a direct connector to the mainboard charge IC. This cell matches that voltage rail and physical footprint. No adapter or wiring change is needed.\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 bench, monitoring BMS cutoff at both ends. The protection circuit tripped correctly at low-voltage threshold and accepted charge current without thermal event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging if the option is available. Run one full discharge down to automatic shutoff, then charge uninterrupted to 100%. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current cycles begin.\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 B2000 Prime after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe B2000 Prime's fuel gauge IC retains the discharge curve of the old, degraded cell after replacement. When the new cell hits a voltage point the IC associates with imminent cutoff — even though the new cell has capacity remaining — the OS triggers an emergency shutdown. This is not a fault in the replacement cell. One full uninterrupted discharge-to-shutoff cycle followed by a complete charge resets the coulomb counter against the new cell's actual voltage curve. After that cycle, shutdowns at 20–30% should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell has higher internal impedance than a broken-in cell. On the first charge cycle, the charge IC pushes current into that higher-impedance cell, and some energy converts to heat rather than stored charge. This is normal and typically resolves after two to three full cycles as impedance drops. If warmth continues past the third cycle or the device becomes hot to touch, stop charging and check that the battery connector is fully seated flat against the mainboard contact pins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404278988890,"sku":"BWCS-AVS500SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404279021658,"sku":"BWCS-AVS500SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404279054426,"sku":"BWCS-AVS500SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVS500SL-1.webp?v=1779369549","url":"https:\/\/batteryweb.com\/products\/highscreen-b2000-prime-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
