It fits the 59 Xenon and P336688 variants and matches the OEM voltage and capacity spec. The flat polymer cell slots into the same bay as the factory unit with no modifications required.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e59 Xenon and P336688 fitment:\u003c\/strong\u003e\n    Both variants run the same charge IC and use the same connector pinout, so one cell covers either board revision. The BMS handshake is handled by the charge IC on the motherboard, not inside the battery pack itself.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the 59 Xenon motherboard. The charge IC accepted the cell without fault flags, and the BMS cutoff triggered correctly at the low-voltage threshold — no runaway charging observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The fuel gauge IC on the 59 Xenon calibrates its coulomb counter against the cell's discharge curve on that first pass — skipping this with high current input leaves the gauge reading against stale data.\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 Archos 59 Xenon after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 59 Xenon's fuel gauge IC retains the discharge curve from the old cell after a swap. When the new cell hits a voltage the gauge hasn't mapped yet, the phone reads 20–30% remaining but the modem or display load pulls voltage below the cutoff threshold. The processor sees an undervoltage event and shuts down before the gauge catches up. One full discharge to automatic shutdown followed by a full charge resets the coulomb counter and eliminates the premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first few charges after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has higher internal impedance than a broken-in cell. The 59 Xenon's charge IC pushes constant current into this higher impedance, which converts more energy to heat than it would on a cycled cell. This is normal for the first three to five charge cycles as the cell's impedance drops toward its rated level. If the back stays hot to the touch beyond five full cycles, check that the charge IC is not stuck in a fast-charge state — plug into a 5V 1A charger and verify the phone reports standard charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392046628954,"sku":"BWCS-AVX590SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392046661722,"sku":"BWCS-AVX590SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392046694490,"sku":"BWCS-AVX590SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVX590SL-1.webp?v=1779143124","url":"https:\/\/batteryweb.com\/products\/archos-59-xenon-replacement-battery-38v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
