The issue with li-ion batteries is spreading a bit further. Lenovo recalled 100,000 Sanyo notebook batteries this week - the previous battery recalls were all Sony batteries.
The latest recall involves batteries made by Japan's Sanyo Electric Co. and follows four reports of overheating. In one case, a user suffered minor eye irritation, the company said.
The Chinese PC maker, which has its world headquarters in Research Triangle Park, said consumers should stop using the recalled products immediately. It said the batteries can overheat if the laptop is dropped a certain way, striking the battery on a corner edge.
Today Lenovo and Sanyo announced they will share the battery recall costs.
In September, Lenovo and IBM recalled more than half a million notebook computer batteries made by Sony after a computer caught fire at Los Angeles International Airport.
That recall was part of a wave of over 9 million recalls that also involved laptops from Dell Inc., Apple Inc. and Toshiba Corp.
Both Sanyo and Lenovo said this time the defect is in the design of the battery packs, which were jointly designed by the two companies and tested for impact-resistance by Lenovo, and not in the internal battery cell, designed by Sanyo alone.
