Enterprise storage controllers use cache memory to manage data transfers between connected servers and storage drives.
During normal operation, some write data may remain temporarily in controller cache. If the storage system experiences an unexpected power failure, that data needs protection until it can be safely recovered or committed to storage.
The HPE AD626B provides backup power for compatible EVA controller cache systems, helping protect data that has not yet been written to disk.
Important: This is a controller cache battery, not a UPS. It does not provide backup power for the complete storage array.
The AD626B is commonly associated with the following legacy storage families:
Some suppliers also list the battery for other EVA controller configurations. However, compatibility should always be confirmed using the installed battery part number and the relevant storage system maintenance documentation.
Do not assume that every EVA storage array uses the same battery assembly.
A controller cache battery may require replacement when the storage system reports a battery fault, reduced backup capacity or a battery-related warning.
Battery condition is particularly important in older EVA systems because the original components may have been in service for many years.
Before purchasing a replacement, check the battery status through the available EVA management tools and confirm that the issue is not related to the controller or its connections.
When replacing the battery, follow the correct maintenance procedure for your EVA model to minimise the risk of data loss or unnecessary downtime.
A New or unused HPE AD626B may be suitable for maintaining an existing EVA storage system. However, unused batteries can deteriorate during long-term storage.
Before ordering, confirm the manufacturing date, remaining service life and whether the battery has been tested. New condition alone does not guarantee that an older battery is suitable for use.
A Refurbished AD626B may offer a replacement option when original stock is difficult to obtain.
Because this is a battery rather than a passive hardware component, ask whether the unit contains replacement cells and whether its voltage, capacity and backup functionality have been tested.
Also confirm whether the supplied item is a complete working battery assembly rather than an empty housing or battery case.
To avoid ordering the wrong replacement, verify the following details:
For older storage equipment, checking these details before purchase can help reduce delays during maintenance.
