    UPS Backup Battery Tips and Articles

    UPS Backups are designed to protect servers, hubs, switches, and Phone systems in the server room as well as critical desktops, such as supervisors and fax machines in case of power outage to the network. Most UPS systems generate independent power with the use of UPS batteries, which are a configuration of sealed lead acids. Since mobility isn’t usually an issue, lead acid UPS batteries are the most economical method of providing backup power


    UPS Replacement Battery Cartridge.

    Over time UPS batteries will wear out due to sulfation and age. This leads to loss of power capacity and runtime. It is recommended that you replace your UPS battery every 2-5 years. Please refer to the owner’s manual for the specific replacement cycle of your UPS batteries. It is critical to use high quality UPS replacement batteries to avoid damage to the UPS backup system and to prevent hazardous condition. That is why AtBatt.com carries only top brands of lead acid batteries which have UL, CSA, VDE, and/or other safety certification. AtBatt.com provides a 1-year warranty on each UPS replacement battery cartridge including any wires and connectors. All connections are made with high current gas-tight crimps for excellent reliability and durability.
