An old toothbrush may have almost burnt down my house today.

Update: Found images of the packaging of the recalled toothbrush, and it used AAA standard batteries, not Lithium ones.
Video Title changed and now still baffled how this fire started.

Hear the smoke detector going off, the clothing rack in the bathroom is on fire and spreading, grabbed the fire extinguisher from the kitchen and got the fire put out, then tried to figure out how it started.
The fire obviously started from the middle of the rack, nothing hot or electrical anywhere near it.
Turns out the cause was likely an old Lithium Battery.

My wife bought the toothbrush on sale at CVS about 10 years ago, and kept it in her hanging makeup case ever since. She remembers it being a Colgate Brand.
This was the only possible ignition source the clothing rack.
The walls and ceiling got a bit scorched but did not catch on fire.
Thankfully I had a proper fire extinguisher and was able to quickly put out the fire.
If this happened overnight or while we were gone, the house, and possibly us, wouldn't be here.
A quick google search found this, and more:

If you have one of these toothbrushes hanging around, get rid of it now.

This was a Colgate toothbrush as described in the CBC link above.
As this is considered a 'medical device' the US Recall was done by the FDA, not the CPSC.
