Adding devices to the catalog is buggy around battery and battery mah

[notmayo]

Description

I didn't know what to put for battery or battery mah, so I first tried -- for both as a similar module has: but I cannot save. Enter a 0 for battery mah gives an error in server.log. Typing 1, every thing is fine. Some boards, like this one and a sibling board from the same manufacturer, does not have a battery integrated. These fields probably do not need to be required, and general input sanitation on these fields would be beneficial.

Secondary, the fields "Bands" and "Firmware" would probably be better suited as checkboxes or a drop down list or some other specific list of known list of values.

Steps to Reproduce

1. Go to 'Catalog'
2. Click on 'Manage Catalog'
3. Click on '+Add Item'
4. Enter a '0'
5. See error

Expected Behavior

To be able to not have this field required and protect the application from not being able to load due to a value.

Actual Behavior

Application will not start due to the "invalid" database value.
