It powers the controller's cache during unexpected power loss, giving the RAID module time to flush in-flight writes to disk. Cross-references include OEM part numbers 1K178, LI103450E, FDL00-150137-0, 1K240, 7F134, Y0229, C0887, and 13JPJ.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePowerEdge RAID controller compatibility:\u003c\/strong\u003e\n    These PowerEdge models share the same PERC controller architecture and use the same 3.7V single-cell backup battery with an identical connector and BMS handshake profile. Swapping between 2600 and 2650 variants does not require any hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, discharge, and BMS communication cycles on a PERC controller. The BMS negotiated correctly, reported cell voltage within the expected acceptance window, and flagged no fault codes during the test sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLearn cycle initiation after swap:\u003c\/strong\u003e\n    After fitting this battery, trigger a learn cycle from the controller management interface — StorCLI: \u003ccode\u003e\/cx bbu start learn\u003c\/code\u003e, or check status via \u003ccode\u003e\/cx bbu show\u003c\/code\u003e. The controller holds write-through mode until the learn cycle completes and the backup window estimate is recalibrated against the new cell's actual capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRAID controller staying in write-through mode after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWrite-through mode is not a fault — it is the controller protecting your data while it has no verified backup window. After a battery swap, the PERC controller does not automatically trust the new cell. It waits for a completed learn cycle before switching back to write-back mode. The learn cycle typically takes 24–72 hours under normal server load. If the cycle is still pending after 72 hours, confirm the battery is seated fully and run \u003ccode\u003eStorCLI \/cx bbu show\u003c\/code\u003e to check learn cycle state and current cell voltage — expected resting voltage is approximately 3.6–3.7V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eManagement console reporting a battery error days after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PERC controller runs its battery self-assessment on a timed schedule, not at boot or at the moment of installation. This means a newly installed cell may pass initial connection checks but still trigger a battery error when the first scheduled assessment runs — sometimes 24–48 hours later. The error usually clears on its own once the learn cycle has finished and the controller has logged a full charge-discharge recalibration. If the error persists past 72 hours, pull the current learn cycle status with \u003ccode\u003e\/cx bbu show all\u003c\/code\u003e and verify that \"Learn Cycle Active\" reads \"Yes\" and cell voltage is holding above 3.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416094048346,"sku":"BWCS-RAD2600SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416094081114,"sku":"BWCS-RAD2600SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416094113882,"sku":"BWCS-RAD2600SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RAD2600SL-1.webp?v=1779760285","url":"https:\/\/batteryweb.com\/products\/dell-poweredge-2600-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
