Hereof, will FiOS work without backup battery?

The battery is only needed to provide backup power for telephone service. If you unplug the BBU from 110V AC and there is no working battery installed, the ONT will shut down and all FiOS services will stop.

Secondly, what is the Verizon FiOS battery backup for? With an active battery, the BBU will provide backup power for your basic FiOS voice services, including Emergency 911 dialing, for up to 8 hours in the event of a commercial power failure. You are responsible for purchasing and/or replacing the battery in the BBU.

The thing is, the unit is in a charger already. The FIOS box the houses the battery has a charger built-in. It runs off AC current and the battery is there to maintain service should the power go down. If it doesn't, you will need to replace the battery.
