The one with addl battery

Everytime i have a new phone, the one thing i would always find myself is looking for an extra battery.  It's a little frustrating when your battery fails you, even on a camera, a phone or any gadget for that matter.  Like during simone's moving up day, I was all set to take pictures only to find out that i wasn't able to charge the camera so after a few shots, the camera turned off by itself.  I should have bought a maha powerex mh-c9000 so i can enjoy longer life for our batteries. It also usually happens to my phone batteries and ipad. hmmm, i really need to find a way to make my gadget's battery life stay longer. :)
