Nate McGuine with Fastphonerepair.com said exploding cell phone batteries are very rare. He said they can be caused by a variety of issues, such as excessive charging, excessive heat, or batteries being old.
“What happens is the cells break down, and they expand,” McGuine said. “They don’t have anywhere to go because batteries are tightly sealed and they can actually explode out.”
