Sony's share price has been hit by both the recall and the recently-announced delay to the European launch of its new Playstation3 video games console.
The shares are down more than 10% since the laptop battery problem emerged in mid-August.
Sony Energy Device Corporation also makes batteries for laptop makers including Hewlett Packard, Sharp and Hitachi.
It produces similar batteries for many other portable electronic devices, such as DVD players and games consoles, but so far there has been no sign of a recall affecting any of these products.
