Overview

Cache backup batteries keep the controller cache protected if mains power is lost, and the 5541807-A is the battery for that role in the Hitachi VSP. The same part is also listed for the HP XP P9500.

The battery carries a second number, HHR-33AH7W1. You may find that code printed on the battery itself, so if your label shows HHR-33AH7W1 rather than 5541807-A, you are looking at the same part.

Storage teams replace these batteries when the array reports a battery fault, or as planned maintenance. Ordering a set at once makes sense when several batteries in a system were fitted at the same time.

New, Refurbished and Used units are available. New and Refurbished come with your choice of 1 year or 3 years of warranty. Used units carry 90 days. Send the number of batteries you need and we will reply with pricing.
