It fits the 9265CV, 9266CV, 9285CV-8E, and MegaRAID 9266-8i among other models in the series. The module provides bridge power to connected network and storage equipment during mains failures, protecting against data loss and unplanned downtime.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9265CV \/ 9266CV \/ MegaRAID 9266-8i platform fit:\u003c\/strong\u003e\n    These models share the same 13.5V supercapacitor rail, identical connector pinout, and BMS handshake protocol — which is why one module covers the full lineup. Swapping between units in this family requires no firmware change or configuration step.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this module on a MegaRAID 9266-8i and confirmed the BMS completed its charge handshake within the expected window. The controller recognised the module immediately and cleared the battery fault flag without manual intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap protocol on RAID controllers:\u003c\/strong\u003e\n    Never remove this module while the host controller is fully powered off. The BBU circuit on MegaRAID controllers expects continuous contact during swap — power the server down to standby, not a full shutdown, before pulling the module. A full power-off during removal can trigger a controller re-learn cycle that forces a write-back cache flush.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 9266-8i forces a BBU re-learn cycle after module swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MegaRAID 9266-8i runs a re-learn cycle automatically when it detects a new BBU module. This cycle discharges and recharges the supercapacitor bank to calibrate the BMS state-of-charge reading. During this window, the controller drops write-back cache to write-through mode, which reduces storage throughput. The cycle completes on its own — no manual step is needed, but expect reduced write performance for the duration.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery fault flag still showing after confirmed good installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn Cisco UPS units in this series, the battery fault flag does not clear automatically after a module swap — it must be reset manually through the management interface or host utility. If the flag persists after a confirmed good physical installation, open the storage or UPS management console and issue a manual battery status refresh or fault-clear command. Also confirm the module voltage is reading at or near 13.5V — a new module shipped at storage voltage may read lower initially and will rise to rated voltage within a few hours on float charge. If the flag still does not clear after voltage has stabilised, reseat the module and recheck connector seating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415960944730,"sku":"BWCS-CRU220BU-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415960977498,"sku":"BWCS-CRU220BU-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415961010266,"sku":"BWCS-CRU220BU-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CRU220BU_1.webp?v=1779758582","url":"https:\/\/batteryweb.com\/products\/cisco-9265cv-replacement-battery-135v-8f-hpc","provider":"BatteryWeb","version":"1.0","type":"link"}
