Boeing said the regulator had set a "high bar for our team and our solution".
BBC: Boeing's Dreamliner battery fix approved by US regulators
Boeing said it was deploying teams to help the airlines install the redesigned system.
The 787s will get the fix in approximately the order they were delivered, Boeing said.
Boeing said it has stationed teams around the world to begin installing the fix.
Boeing said the plane, built largely of composite materials, would leapfrog advanced technologies at Airbus.
Boeing said that it was carrying out an investigation to find out what caused the battery malfunctions.
Boeing said it was investigating the incident and noted it was too early to draw any parallels.
Boeing said it was building extra time into the testing schedule to reduce the risk of further delays.
The batteries in question are manufactured by Japan's GS Yuasa, under a subcontract to France-based Thales, Boeing said.

The layered fix aims to prevent any fires from developing, and Boeing said it was confident in its approach.
CNN: FAA approves proposal for fixing Dreamliner battery woes
Boeing said it has hundreds of experts focused on solving the battery situation.
Boeing said it would take weeks before a further date could be set.
Boeing said new batteries and kits with the parts for the new battery systems are ready to be shipped immediately.
The batteries in question are lithium batteries manufactured by Japan's GS Yuasa, under a subcontract to France-based Thales, Boeing said.
Boeing said the deal meant it had now received more than 10, 000 orders overall for aircraft from the 737 family.
Boeing said Friday it will not deliver any Dreamliners to its customers as it works with the FAA over the battery concerns.

Boeing said the 737 was the "undisputed best-selling jetliner in the world".
In November, Boeing said it had begun making five 787s per month.
Boeing said the fire appeared unrelated to previous problems involving 787 electrical power systems and that it was cooperating with the safety board.
Boeing said while the replacement rate was "slightly higher" than usual, the changes were "routine maintenance" and were not due to any safety issues.
They were expected to resume "in the weeks ahead, " after it installs the changes on planes at the two factories where they're assembled, Boeing said.
The plane landed about two hours later without incident, Boeing said.
On Friday, Boeing said it would put deliveries of the 787 on hold until the FAA approved its plan to ensure the safety of the batteries.
Boeing said it has deployed teams around the world to begin installing the new battery systems, while kits for parts and new batteries will be shipped immediately.
Boeing said in a statement that its technical experts are working "around the clock" and are focused on "resolving the issue" and returning the 787 to service.
The 737 Max, which is a new-engine variant on the Next Generation 737, builds on these strengths, Boeing said, reducing fuel use and carbon dioxide emissions by 13%.
Worldwide, Dreamliners fly 150 flights daily, Boeing said last week.
When contacted by the BBC, Peter Conte, a spokesman for Boeing said the firm was "choosing not to comment on Ms Hersman's remarks as the matter was under active investigation".
Boeing said the fire was traced to a battery unit that helps to power electrical systems when the engines are idle -- typically while a plane is being serviced or cleaned.
However, in a possible sign of confidence, Boeing said that its forecasts for revenues and profits this year were not being adjusted to reflect any impact from the suspension of Dreamliner flights.
