Kyle Andrews bought a lithium battery-powered e-bike a few months ago. Everything was fine, he said, until he tried charging a new battery with a charger he already owned.
"It exploded right in front of me," said Andrews. "When I turned over my head it looked like I was staring into the sun."
The store where Andrews purchased the e-bike and battery says they've sold about 20 units and have had no other complaints from customers.
Toronto Fire Services Capt. Stephan Powell says he's heard of lithium batteries catching fire, but that typically the problem is how they are charged, rather than the battery itself.
