Computer Backup Batteries

Computer backup batteries are alternative power sources for a computer when the main power source gets disrupted or is unavailable. Computer backup batteries are made from Lithium Thionyl Chloride which offers high energy density and low voltage discharge functionalities.

What are computer backup batteries used for?

These batteries, also called terminals, are single cell blocks that provide back up power and therefore retain settings within computers when the power supply is disrupted. In corporate buildings or power station facilities, battery rooms filled with numerous terminal blocks ensure uninterrupted power supply in data centres.

Computer backup batteries are used in motherboard hardware to keep configuration memory and timing/clock settings when the PC is switched off.

When used in the UPS (uninterruptible power supply) of a computer, they provide enough time for the user to properly shut down the machine when power outages occur. As BBU's (battery backup units) they act as onboard disk buffers to retain the contents of the cache after a power disruption.

Types of computer backup batteries

Many varieties of computer backup batteries exist, and they are usually categorised by the supplier/manufacturer of the corresponding PC brand, model or type.
