UPS no battery

Without included battery

— models without any battery included. On the one hand, such UPSs require additional effort and time to prepare for operation — you need to find and purchase a suitable battery. On the other hand, this battery can be chosen according to your needs and budget, while the battery in set is not always the best option in terms of performance.

In this configuration option, models are sold that do not have compartments for batteries and are designed to use only external batteries (see the relevant paragraph).
