It fits the Windows Mobile PDA-phone directly, using the same OEM-matched connector and cell format. Capacity figures come from the product data sheet — 9.62Wh at 3.7V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePPC6800 and PPC-6800 compatibility:\u003c\/strong\u003e\n    Both model designations share the same battery bay dimensions, connector pinout, and BMS handshake voltage. The 35H00077-00M and 35H00077-02M part numbers are cross-compatible across PPC6800 production runs — the cell and protection circuit are identical.\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 PPC6800 platform. The BMS accepted the charge IC handshake without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold during a controlled deep-discharge test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one full discharge to automatic shutdown and then charge uninterrupted to 100% before normal use. The PPC6800's fuel gauge IC was calibrated to the old cell's discharge curve — skipping this step causes the percentage display to read inaccurately from the first charge.\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 PPC6800 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PPC6800 combines modem, screen, and PDA functions in one load cycle. When the display and radio draw peak current simultaneously, a new cell with an uncalibrated fuel gauge can report 25% remaining while the actual terminal voltage drops below 3.2V under load. The BMS reads that voltage sag as a low-cell condition and cuts output immediately. Running one full calibration cycle after installation closes the gap between the coulomb counter's estimate and real cell state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically in the first few days\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is the fuel gauge IC recalibrating against the new cell's discharge curve. The original firmware-stored curve was built around the aged cell it shipped with — a fresh 2600mAh cell has a steeper, higher-capacity curve that the IC hasn't mapped yet. Erratic jumps of 5–15% are normal in the first two to three cycles. After two full discharge-charge cycles, the coulomb counter stabilises and percentage reporting becomes consistent.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405159956570,"sku":"BWCS-VX6800XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405159989338,"sku":"BWCS-VX6800XL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405160022106,"sku":"BWCS-VX6800XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VX6800XL-1.webp?v=1779370334","url":"https:\/\/batteryweb.com\/products\/audiovox-ppc6800-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
