Hi I have a Canon rebel t3 i bout about 4-5 years ago i have never dropped it or gotten it wet last week the battery drained out I noticed I lost the charger so went to Best Buy they said they didnt sale them so i bought a universal charger i left the battery charging all night in the morning i checked it with my camera turned on fine i saw the battery was full i set it aside leter that day i twisted on the tripod for a photoshoot and the camera didnt turn on. I switched the battery with my fried which she has a canon camera as well and my battery worked on her camera and her battery didnt work on mine
