Lenovo recalled the Sanyo-manufactured fire hazard batteries last week, after five incidents either caused injury to users or damaged their property.
It is Lenovo’s second major laptop battery recall in six months, after being one of a number of major laptop suppliers which fell foul of Sony-manufactured fire hazard laptop batteries last year.
Sanyo’s share of the recall costs comes as the loss-making company faces an investigation into its dealings by Japan's securities watchdog the Securities Exchange and Surveillance Commission (SESC).
It is not known what the total cost of the recall will be, and how the two firms will split the cost. But the pair have decided to share the cost because the battery in question was jointly developed by both companies, said Reuters.
The major Sony recall last year cost it an estimated £230m, but the number of units involved was well over six million.
