London, Jan 31 (ANI): Aerospace giant Boeing has defended the use of lithium-ion batteries in the Dreamliner after Japan Airlines and All Nippon Airways said they changed a number of them in the past few months.
Boeing said while the replacement rate was 'slightly higher' than usual, the changes were "routine maintenance" and were not due to any safety issues.
The airline backed the battery as it reported record revenues of 22 billion for the last quarter of 2012, the BBC reports.
Battery problems have led to the grounding of the entire fleet of 787s.
The planemaker, which has orders for more than 800 Dreamliners, however, said the issue had not impacted its production plans.
It said it had not asked any of its suppliers to slow down deliveries of parts.
According to the report, Jim McNerney, chief executive of Boeing, said that it was "business as usual", adding that the firm planned to go ahead with a planned ramp-up in production.
The Dreamliners were grounded after a battery in a Japan Airlines 787 plane caught fire in Boston, while an All Nippon Airways flight was forced to make an emergency landing because of a battery malfunction earlier this month. (ANI)
