I’m having trouble with my cordless phone battery.  The trouble is me; every time I’m at a store that sells batteries I remember that I need one, but of course, I always forget to write down the model number and stick it in my wallet.  So I pour over the seemingly hundreds of batteries available, then throw up my hands in frustration.  By the time I get home, I once again forget to write down the necessary information.

Maybe I should just cut my losses and search online.  What do you think?
