    If they have generally stayed above the 80% charge for their entire lifetime, in a location with a nice even temperature, you can expect them to be functioning well closer to the 4 or 5-year mark.

    UPS Batteries for Power Backup

    Do you have an Uninterruptible Power Supply (UPS) connected to a server, telephone system, workstation or to a home computer? UPS systems are a must for anyone that doesn’t want to experience the frustration of losing data, hours of work or just access to essential electronic equipment during a power outage.

    Setting up a UPS unit is fairly straight forward, put it under the desk or close to the equipment that will be connected to the outlets in the back of the unit. Plug in the equipment that you want to access the back up power generated by the UPS. Then plug the UPS into the wall. That is really all the basic requirements. Some UPS units are more advanced and have load balancing software, and many more fancy features but the general set up and operation of a UPS system is pretty simple. However, what happens when the alarm on the UPS starts going off and signals that it is time to replace the battery in the unit? Continue reading
