TUCSON, Ariz.—Federal investigators announced they will conduct more tests on Boeing’s Dreamliner 787.

The tests will be conducted by the National Transportation Safety Board at a facility in Arizona, beginning Tuesday.

Investigators with the board said tests conducted in Washington showed that a lithium-ion battery that caught fire on a plane in Boston was not overcharged.

Suspicions about the batteries and a possible fire risk prompted the United States and other nations to ground all 50 Dreamliner jets worldwide last week.
