Backup Battery

Backup battery styles are designed to give power to a wide array of systems, when primary power sources fail (or otherwise become unavailable). These types of batteries make it possible to enjoy service without interruption, by offering vital backup in the event of primary power problems.

There is an assortment of battery styles, ranging from compact, single-cell designs which retain clock times and dates within computers, to bigger battery room facilities which provide “juice” to large data centers, via uninterruptible power supply systems. Typical forms of small backup batteries include primary cells and re-chargeable styles, which are constantly being re-powered via the primary power supply (while it is still functional).

Specific Types of Backup Batteries

In order to provide targeted power within specific systems, a range of backup battery types have been created. These styles of batteries are used in order to offer secure power to aircraft emergency systems, burglar alarms and computers (to name just a few examples).

Aircraft Emergency Batteries

Crafted in order to provide power to essential instruments on board, aircraft emergency batteries will kick in and supply juice when engines stop producing power. In other words, in the event of an emergency which is related to power supply, this type of backup battery will be utilized in order to help pilots make safe landings and protect the safety of all people onboard.

These types of backup batteries will be found in a range of aircraft instrumentation, including navigation equipment, emergency lighting units, oxygen systems and so on. Typically, batteries which are used for this purpose will be made from nickel-cadmium or valve-regulated lead acid.

Burglar Alarms

Backup batteries which are utilized in order to power up burglar alarms are designed to stop thieves from disabling alarm systems by shutting off primary power sources to a building. In addition, these sorts of batteries give vital juice which powers up cell phone systems that deter phone line snipping.


These days, computer motherboards also feature backup batteries which are designed to keep real-time clock circuits running in the event of power interruptions via primary sources. In addition, these batteries keep configuration memory in operation. Typically, batteries which are utilized for this purpose are crafted from lead-acid.


Phone systems are also examples of systems which commonly feature backup batteries. Usually, these types of telephone systems will be of the digital passive optical network style. These networks feature active units on the telephone exchange side, as well as the user side. Because of the presence of these batteries, it is possible to enjoy standby power that keeps a system running in the event of emergency.

Backup Battery Care Facts

In order to ensure that backup batteries are running properly, it’s important to run periodic discharge tests on these products. Manufacturers typically recommend testing backup batteries twice per year. Some people choose to have their backup batteries tested by professionals who run tests and then issue reports on the current condition of these battery designs.

Backup Battery Buying Tips

In order to choose high-quality batteries which serve their purposes flawlessly, consumers who wish to invest in these designs should consider the reputation of the backup battery manufacturer and/or retailer. In general, high-quality batteries that work well for most consumers will receive strong and positive reviews online, so prospective buyers may wish to source out these product reviews before making a final decision about which batteries to buy.

The features of various batteries used for backup, as well as their warranties and respective prices, should also be considered. Once a superlative battery design which fits a corporate or personal budget has been found, a consumer may purchase this product, whether on or offline.
