VARTA 730865-001 Battery pack 3.6V NiMH 150mAh with Cable The VARTA 730865-001 is a sealed, rechargeable NiMH battery pack specifically designed for HP/HPE server use. It contains VARTA NiMH cells assembled with an attached connector cable for easy installation. One distributor notes it as the “HP Battery Pack 4.3V NiMH 150mAh (730865-001) for HPE ProLiant DL580 G9 – 4GB Flash Back Write Cache FBWC, 24-inch cable” , indicating it is built for the DL580 G9 server’s cache memory backup. In operation, this battery pack provides backup power to the Smart Array RAID controller’s cache memory (FBWC) during power loss. It is used in HPE ProLiant DL580 Gen9 servers and associated Smart Array controllers, ensuring cached data is preserved if the main power fails. This pack includes a pre-attached ~24-inch cable and connector for flexible placement inside the server chassis. The use of NiMH chemistry means no memory effect and a longer cycle life than older NiCd batteries. As an OEM part built to HP specifications (often branded by VARTA for HP), it meets the reliability standards required for enterprise servers. In summary, the 730865-001 is a compact, high-quality NiMH battery module that integrates plug-and-play with HP’s DL580 Gen9 server systems. It is rated at 3.6 V nominal (about 4.3 V fully charged) and 150 mAh capacity, and is primarily used to keep the server’s write-cache memory powered during outages. The long attached cable and sturdy connector simplify installation in the server backplane. Altogether, it is a specialized backup battery ensuring data integrity in HP storage controllers.
