Any business or any home office needs to have a UPS battery backup system running from day one in order to protect the business's data and make sure that service isn't interrupted. For businesses that deal in telecommunications or other industries where continual service is the core of what the business offers to customers having a high quality UPS battery backup is essential. Besides having a high quality UPS battery backup every business should have at least one APC UPS battery backup tester that can gauge the power supply for the UPS battery backup and make sure that the UPS battery backup is running on full power and is ready to go at anytime. Businesses can choose from one of three different kinds of UPS battery backups. It doesn't matter what type of UPS battery backup that a business chooses to use an APC UPS battery backup tester should always be used regularly to make sure that the UPS battery backup is functioning and is ready to go when needed.

Using an APC UPS battery backup tester is probably most important for businesses that use an offline UPS battery backup. An offline UPS battery backup system stays dormant until the power goes off and then it instantly turns on and redirects its own power to the original source to protect data and functionality. Businesses can save money by using an offline UPS battery backup since it doesn't do anything until the power actually goes off. However since the unit will probably just sit until something happens and there is a power shortage, it is even more important to use an APC UPS battery backup tester on an off line UPS battery backup then it is to use a backup battery tester on the two other kinds of UPS battery backup systems, because the unit can sit for months without being used. Sitting around for a long time means that if something is wrong with the unit or if the battery is not holding a charge then no one will know that until the critical moment when the offline UPS battery backup is needed and by then it will be too late.

Using an offline UPS battery backup can be a more economical option for businesses than using an online or line-interactive UPS battery backup so it makes sense that most small businesses or start up businesses go for an offline UPS battery backup system at first, but make sure that an APC UPS battery backup tester is purchased too so that the UPS battery backup system can be tested regularly. Regular testing of the offline UPS battery backup system should be done according to a schedule. A smart way to keep track of when the UPS battery backup system has been tested is to write on a calendar each date that the UPS battery backup system should be tested and then when someone uses the APC UPS battery backup tester that person can make a big red "X" through the date so that it's clear when the test was done.
