Questions about this item

What comes in the box with the APC Smart-UPS SMX120BP external battery pack and do I need to buy cables separately?

Which capacity version of the APC Smart-UPS SMX120BP should I choose for my 120 V Smart-UPS system?

This model provides a single 1200 VAh capacity at 120 V; select it when your compatible Smart-UPS requires that exact rating to extend runtime.
