back up power

The ordering of the unit was very easy, and shipping was very prompt. I now feel more secure when the power goes out. Will be installed soon.

Where is the battery?

Everything was delivered fine packaged well only problem when the electrician tried to hook everything up today discovered there was no battery. No doubt a key ingredient factory pure never bothered to tell me I needed to order a battery.
