Most likely it had tried to recharage a non-rechargeable battery. Lithium
cells in particular will explode quite violently if you try to recharge
them...

Of course a look at the schematics would have told you whether the system
tried to recharge the battery, but have you ever tried to get schematics
to a PC? But that's another rant...
