What Is A Cache Battery Module And Why Is It Important For Your Computer
A cache battery, which is also known as a RAID battery, is basically used to protect the data in the cache of the RAID controller. In computers, the cache is a small temporary storage area for the data that is being written on the disk. The main function of the cache battery comes during power outages, as the cache battery module provides power to the computer cache so that the data can be written on the disk before it is lost. Generally, most of the cache battery replacements come with a 2-4 watt-hour capacity, which is more than enough to power the RAID cache for a few minutes.

Types of Computer-Compatible Cache Battery
There are no major types of cache batteries, however, they can be classified into three main categories based on their manufacturing material. To find the most compatible cache battery for your motherboard, you must know the difference between the following types:
- Nickel-cadmium (NiCd) batteries are the oldest type of cache battery. They are relatively inexpensive, but they have a shorter lifespan than other types of cache batteries.
- Nickel metal hydride (NiMH) batteries are a newer type of cache battery. They are more expensive than NiCd batteries, but they have a longer lifespan.
- Lithium-ion (Li-ion) batteries are the newest type of cache battery. These types of cache batteries are the most expensive type, but they have the longest lifespan.
The type of cache battery that is best for a particular computer will depend on the computer's requirements. For example, a computer that is used for heavy-duty tasks may require a Li-ion battery, while a computer that is used for light-duty tasks may be able to use a NiCd battery. However, you should always try to opt for Li-ion batteries as they are the norm in IT hardware these days.
