Investigators are still trying to find out what caused the two battery incidents that grounded the 787. But McNerney said the company has learned nothing that makes him think they made a mistake in picking lithium-ion batteries. The 787 was the first plane to use the batteries so extensively. Boeing liked them because they charge quickly and hold more power than other batteries of the same weight. The company declined to say how many of the batteries have been replaced. But Japan's All Nippon Airways said it had replaced batteries some 10 times because they didn't keep a charge properly or connections with electrical systems failed. Japan Airlines also said it had replaced some 787 batteries. Among U.S. airlines, only United flies 787s. United Continental Holdings Inc. spokeswoman Christen David declined to say on Wednesday whether it has replaced batteries on any of its six planes. Lot Polish Airlines said it had not had problems with the batteries. One of its two 787s remains stranded in Chicago because of the grounding order. The FAA said on Wednesday that it had not been notified of ANA's battery replacements either by the airline or by Boeing. The FAA requirements are detailed and spell out a number of exceptions. In general they require a report only for malfunctions or defects that cause a serious problem such as a fire or an engine failure. Boeing said it expects to deliver 635 to 645 commercial jets this year, up from 601 last year. The 46 787s that Boeing shipped to customers in 2012 helped it deliver more planes than European rival Airbus for the first time since 2003. Airbus expects to deliver more than 600 planes this year. On Wednesday, Boeing reported a 2012 profit of $3.9 billion, or $5.11 per share, last year, a 3 percent decline from 2011. Revenue rose 19 percent to $81.7 billion. It predicted 2013 earnings of $5 to $5.20 per share, with revenue of $82 billion to $85 billion. The outlook assumes "no significant financial impact" from the 787 being out of service. Boeing said it would update its 2013 prediction if the assumption changes. Shares of Chicago-based Boeing rose 94 cents to close at $74.59.
