Lenovo recalled around 500,000 batteries last year, which were made by Sony, which were also a fire hazard. That move came after similar batteries were recalled by Dell, Apple, Toshiba and others.
The latest move by Lenovo is now set to be copied by other laptop manufacturers who use similar Sanyo batteries.
The batteries in question can suffer from overheating, and past incidents have caused an injury to one user and damage to other users’ property.
The batteries affected were manufactured for use with ThinkPad notebook computers that shipped worldwide between November 2005 and February 2007.
Lenovo sold the batteries with new notebook computers or as optional or replacement batteries on the ThinkPad R60 and R60e Series, ThinkPad T60 and T60p Series, and the ThinkPad Z60m, Z61e, Z61m, and Z61p Series computers.
Lenovo says existing battery users should instead run their machine on AC power until getting a free replacement, particularly if there is a chance the battery can get knocked about in transit.
