Keep your enterprise storage running smoothly. Cache batteries protect critical write data when power goes out, which is essential for server reliability. At Direct Macro, we offer a wide selection of cache batteries for RAID controllers and enterprise storage systems, so you can find the right fit for your setup.
If you are upgrading old hardware or replacing a failed unit, getting the right cache battery quickly is important. We carry genuine enterprise cache batteries from top manufacturers, and they are ready to ship to you.
A RAID controller cache battery keeps data in the controller’s write cache safe during sudden power outages or shutdowns. Without a working battery, that cached data could be lost or corrupted. We offer cache battery replacements for many controller models, so you can easily find one that fits your system.
Battery Backup Units (BBUs) are key to reliable storage in enterprise settings. We provide server cache battery and BBU options in different sizes and capacities, so you can find a compatible choice whether you have one server or a large data centre.
Buying a quality cache battery is not only about meeting hardware requirements. It also protects your data and helps your operations run smoothly.
Power interruptions can occur at any time. When this happens, a RAID battery backup keeps the data in the controller’s cache safe until the system is running again. Without this protection, even a short outage can cause incomplete writes and file corruption. Our enterprise cache batteries are tested to provide reliable data protection when you need it most.
A good cache battery helps protect your server storage and keeps your system running well. Many RAID controllers switch to write-through mode if the battery is weak, which can slow down your storage. Replacing an old battery brings back full write-back caching and keeps your system working at its best.
We know that enterprise environments use many types of hardware. That is why our cache battery selection includes all the major platforms.
We stock Dell cache batteries for PowerEdge servers, HPE cache batteries for ProLiant and Smart Array controllers, IBM RAID batteries for System x and storage arrays, and Lenovo storage batteries for ThinkSystem platforms. No matter which brand you use in your data centre, we have a compatible replacement available.
In addition to the major brands, we also offer batteries for many other storage controllers and server platforms used in different industries. If you are unsure which part you need, our team can help you find the right match based on your controller model or system specifications.
Finding a reliable source for enterprise components should be simple. At Direct Macro, we make it easy with genuine parts, competitive prices, and a team that truly understands hardware. Here’s why IT teams and procurement managers choose us again and again.
We provide only genuine replacement cache batteries and enterprise storage components. We do not sell grey-market parts, and we never compromise on quality. Every unit we offer meets OEM specifications, so you can trust the quality and compatibility of what you install.
As a trusted server hardware supplier, we understand that downtime is expensive. We ship orders quickly, and our team of hardware specialists is ready to answer your questions, confirm compatibility, and help you get back online as soon as possible.

A cache battery is used to power the cache memory on a RAID controller or other hardware devices. It ensures that data in the cache is not lost in the event of a power failure.
In HP servers, the cache battery, often referred to as the Battery-Backed Write Cache (BBWC) or Flash-Backed Write Cache (FBWC), is a battery unit that provides power to the RAID controller's cache. It is important since it protects data during power outages.
The RAID battery ensures that the data stored in the RAID controller's cache is not lost during a power failure by providing temporary power to the cache, allowing data to be written to permanent storage when power is restored.
Cache does not directly affect the battery life of a device like a laptop or smartphone. However, in the context of RAID controllers, the presence of a cache battery is crucial for maintaining data integrity but does not significantly impact the battery life of the server itself.
If the cache is removed, the performance of the RAID controller can be significantly reduced because it can no longer temporarily store and quickly access frequently used data.
Additionally, there would be a higher risk of data loss during power failures, as the RAID controller would lose the ability to save unwritten data from the cache to permanent storage.
A cache battery saves the data in your RAID controller’s write cache if the power goes out. Without it, cached data could be lost or corrupted, so it is essential for keeping your data safe and your system reliable.
Most systems will alert you through management software or BIOS warnings if the battery health gets worse. You might also notice the controller switching to write-through mode, slower storage performance, or direct hardware health messages.
We stock batteries for Dell, WHPE, IBM, Lenovo, and many other platforms. If you know your controller model, our team can check compatibility before you order to make sure your replacement process is easy.
Both terms mean the same thing: protecting cached data during a power failure. BBU is the broader industry term, while cache battery usually refers to the rechargeable cell inside or attached to a RAID or storage controller.
