Need advice on powering 2 pieces of 3528 warm white led strips ,each strip is 20'' long with 1, 9 volt battery & there will be a on-off switch used also ,i know it will light more than what i am doing because i tried it on a partial strip of blue lights that i had left over from another project & it worked just fine ,i only need to cast light on a small area ,is there anything i need to be aware of ,am i missing anything ?

You'll only get 7-8 hours of operation with a 9V alkaline battery from 20" of light strips.  I just tested a 3528 white strip 20" long and at 9.5 volts it drew 65ma, at 9V it was down to 55ma.  The 9V alkaline is good for 500 milli-amp hours, and realistic you'll get more like 400 before they're pretty dim.

It'll work, but it's not going to be cheap feeding it batteries all the time.
