I'm going to assume you are using a 12v LED strip because that is most common. If that is the case, I highly recommend one of these: http://www.amazon.com/gp/product/B007RQW5WG?psc=1&...

It is rechargeable and works fantastic. You can also use just a 9v battery but it won't last very long and won't be nearly as bright.

By LED strip I presume it is 12v. You could use a lead-acid battery or even a drill battery if it is 12v. If your battery voltage is higher than 12v use a DC voltage step down converter these are pretty cheap off ebay or something.

How long is this piece of string ? Generally they consume around 1A per metre @ 12V.

So, 1 metre, one set of AAs, about an hour, maybe 2
