It replaces OEM part numbers BP3 and 157-10151-00 directly. Dimensions are 43.80 × 34.50 × 5.50mm — measure your original before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVeer and Veer 4G compatibility:\u003c\/strong\u003e\n    Both the Veer and Veer 4G use the same BP3 cell footprint and connector pinout. The BMS handshake is identical across P160U and P160UEU hardware revisions, so one cell covers the full range.\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 Veer unit. The BMS accepted the cell without fault codes, held voltage through screen-on and radio-active load states, and cut off cleanly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to automatic shutdown, then charge uninterrupted to 100% before normal use. The webOS fuel gauge IC calibrates its coulomb counter against that first complete cycle — skipping it causes the percentage display to drift from the first day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Veer reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Palm Veer's fuel gauge IC stores a discharge curve learned from the original cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry and internal resistance. The IC keeps estimating state-of-charge against the old model, so the displayed percentage drifts — often reading higher than reality early in discharge. One full discharge-to-shutdown followed by an uninterrupted charge to 4.20V forces the IC to rebuild its reference curve against the new cell.\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 cell voltage drops sharply under combined modem and display load — a voltage cliff the fuel gauge didn't predict. The phone's protection circuit cuts power the moment cell voltage falls below the hardware floor, even though the percentage counter still showed charge remaining. It is most common in the first few cycles before the coulomb counter recalibrates. After two or three full cycles the IC tracks the actual voltage cliff and the percentage readout catches up — shutdowns at false percentages stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405007683674,"sku":"BWCS-HVP160SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405007716442,"sku":"BWCS-HVP160SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405007749210,"sku":"BWCS-HVP160SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HVP160SL-1.webp?v=1779369805","url":"https:\/\/batteryweb.com\/products\/palm-veer-replacement-battery-37v-920mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
