Query: CAMERA BATTERY

DOESN'T STAY CHARGED AS LONG AS THE ORIGINAL BATTERY DID. I DIDN'T REALIZE THIS SO AFTER I CHARGED IT, I JUST FORGOT ABOUT IT AND WHEN I TOOK IT ON A TRIP (WITHOUT THE CHARGER OF COURSE) THE BATTERY WAS DEAD AND I COULDN'T USE IT. I DEFINETLY CHARGE IT THE NIGHT BEFORE I NEED IT NOW.
