Ouch! First Dell; and now Apple who recently recalled laptops. Perhaps the

There is no elsewhere.  Apple, Dell, HP, IBM, and everyone else buy
batteries from the same manufacturers.

Makes you wonder tho if these manufacturers are putting too much of a load on the batteries, approaching the limits of the batteries.

IMHO, it's a heat problem, not a capacity problem, especially with modern high speed laptops. Which the manufacturers know about, but are keeping quiet and trying very hard to resist a general recall.

Lithium cells come with dire warnings about exceeding temperature ratings, and IIRC, the recommended discharge temp. is <60 deg. and charging temperature is <45 deg. C. Many laptops now operate very near to these temperatures

I notice many new Acer models, and some of the newer Dells (same OEM?) now position the battery pack behind the hinge, i.e. the pack is now "outside" the casing, and hence *much* cooler to the touch, even though the vented air from the laptop interior is extremely hot.

Come to think of it, all the burning laptop photos are of the design where the battery is inside the main body of the laptop.
