It carries OEM part number AB2900AWMC and slots into the original battery bay with the same connector and contact layout. Capacity figures are taken from the product data — 9.99Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX1560 and X5500 compatibility:\u003c\/strong\u003e\n    Both models share the AB2900AWMC form factor, contact pitch, and 3.7V nominal voltage rail. The BMS handshake logic is identical across this Xenium sub-family, so one cell fits both without adapter or modification.\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 controlled discharge on a Xenium X1560 unit. The BMS accepted the charge IC handshake on the first cycle, temperature stayed within normal range, and no protection cutoffs triggered under sustained load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one complete discharge-to-charge cycle at standard rate. The fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skip this step and the OS percentage readout will lag real capacity by 15–20%.\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 Xenium X1560\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the minimum threshold the modem or display backlight needs under peak load, even though the fuel gauge still reads 20–30%. A degraded or uncalibrated cell cannot hold voltage under that instantaneous current draw, so the BMS cuts output to protect the cell. On a fresh replacement, this usually means the fuel gauge IC is still mapped to the old cell's discharge curve. Run one full discharge-charge cycle at standard charge rate and let the coulomb counter remap. After that cycle, shutdowns below 15% are normal — below 10% means recalibration is still incomplete; run a second full cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after sitting in storage with low charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the replacement cell self-discharged below roughly 2.5V during storage, the BMS enters lockout mode and blocks current flow entirely — the phone appears completely dead. Plug into a wall charger, not a USB port, and leave it for 20–30 minutes without pressing the power button. Most Xenium charge ICs apply a trickle pre-charge below 3.0V to bring the cell back above the BMS re-enable threshold. If the charge indicator LED does not appear within 40 minutes on wall power, check that the charger output is at least 5V 1A — underpowered USB sources sometimes cannot trip the pre-charge circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392042565722,"sku":"BWCS-PHX156SL-1","price":24.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43392042598490,"sku":"BWCS-PHX156SL-2","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43392042631258,"sku":"BWCS-PHX156SL-3","price":30.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHX156SL-1.webp?v=1779143125","url":"https:\/\/batteryweb.com\/products\/philips-xenium-x1560-replacement-battery-37v-2700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
