You can power the Arduino with 12v but 7.5v would be better.

7ah current arduino will sustain or not

4

The Arduino takes 10s of milliamps only.

Is this battery under constant charge?

Are you going to power anything other than just the Arduino?

.

5

battery is not in constant charge.
yes other sources will use power from the battery.

6

Do not double post.

7

ok

Depending on how much current will be drawn from the battery it will eventually discharge.

Let's say the battery is new and it is being loaded at 250ma.
Your battery may last up to ~28 hours.
