CRN is reporting that Dell first identified the cause of the failures in Sony manufactured batteries late last year. At the time, however, Dell believed that the faulty batteries were in a small sample of notebooks and decided to recall only 22,000 units.

In letters obtained under the Freedom of Information Act, the line of communication between Richard Stern, acting associate director of the CPSC and John Hodges, a lawyer for Dell, is brought to light:

“Thank you for your full report of November 10, 2005. … In your report, submitted on behalf of Dell Inc. … you indicated that some lithium-ion battery cells manufactured for Dell could contain contaminates that create an internal short circuit. An internal short circuit could result in excessive heat, smoke or flames in the battery pack and possibly beyond, creating risk of thermal burn,” wrote Stern.
