How to Replace an APC 1000Xl Battery

The APC 1000XL is an Uninterruptible Power Supply (UPS) unit, which provides backup power to crucial computer networks, security systems and other electronic devices. To supply this continual power, UPS units rely on rechargeable batteries during blackouts. Over time, the APC 1000XL's maximum charge capacity dwindles and it needs replacement. Without a functioning battery, the unit can't fulfill its main purpose, but fortunately, changing the battery is a straightforward process that will have the UPS unit quickly back online.
