Battery packs contain cells of rolled up metal strips. Sony has said that during production, crimping the rolls left tiny shards of metal loose in the cells, and some of those shards can cause batteries to short-circuit.

The batteries do contain a flammable liquid that contains lithium, and this liquid surrounds a metal coil inside the battery. During the manufacturing process, microscopic pieces of the metal can form in this liquid. Careful
manufacturing can limit the number of these fragments and their size, but won't eliminate them completely.
Q How long does a Dell laptop battery last? When should I consider replacing mine?
A All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell laptop battery when the run time does not meet your needs.
