Considering that my car’s battery is made up of I don’t know how many of those
little cells, can you imagine if they all blew up at once.

Indeed. You're going to need a pretty big cinder block box to charge your car
in...

Never ever ever charge lithium batteries unattended. Build yourself a box out
of cinder blocks for future charging.

Couple of our guys came to check some thing at the shop today, the OSP crew
ready room was full of smoke.
Our horizontal directional drills use sondes in the drill head for tracking
purposes. We recharge the batts every time they come back to the shop.
The batts we use are smaller than normal sonde bats so they fit into an
adapter, sabot type of thing.
The industry standard is double C cells, but the vibrations are such that
normal C cells will give you intermittant service. So most use a special 3
volt battery that is probably just 2 c cells welded with heat shrink.
Our new locators and sondes use a voltage a bit higher than most 3.3 volt
lithium. They like 3.6 volts I believe. So the smaller batteries are adapted
to fit the sonde, but the charger for them requires the adapter.
They really should make the charger such that the larger batts cannot be
put in it.
Just glad we didn’t have a fire. It did blow the corner of a piece of
shelving.
