Boeing Battery Was a Concern Before Failure
Even before two battery failures led to the grounding of all Boeing 787 jets this month, the lithium-ion batteries used on the aircraft had experienced multiple problems that raised questions about their reliability.
Officials at All Nippon Airways, the jets biggest operator, said in an interview on Tuesday that it replaced 10 of the batteries in the months before fire in one plane and smoke in another led regulators around the world to ground the jets.
The airline said it told Boeing of the replacements as they occurred but was not required to report them to safety regulators because they were not considered a safety issue and no flights were canceled or delayed.

They’ve probably got two more weeks max....before total lack of confidence occurs. This would be a big enough mess to destroy Boeing, if you ask me. They’d have to ask Congress for billions...to survive.
Why not go back to NiCads or NiMH batteries?
They may well have to. But that process of redesigning and flight certifying different batteries, battery charging system, and battery mounting system (larger physical size of NiMH for same energy) will take at least a year.
BTW, I heard the new batteries used by Boeing are the same that make the Chevy Volt a fiery death trap.
I think the Government has a hand in this as well...like making the company “go green” and buy from Obama’s crooked crony companies.
Boeing needs to replace all these new ion batteries with the older more stable batteries. They really have no choice!
Boeing is the largest exporter in the US and too big to fail. Someone should have been riding heard on the EEs, as those guys can’t tie their own shoes.
The way Boeing "designed" the 787 was different from every previous airplane they manufactured. This time they let out specifications, and let outside companies design the subsystems.
The battery system was sourced by Thales, with components from Yuasa and Securaplane.
I have a Yuasa rotary table in the garage. I really need to take precautions to keep it from overheating. Maybe mount some thermocouples on the handles or something. I thought they were a solid company but have my doubts now!
“The way Boeing “designed” the 787 was different from every previous airplane they manufactured.”
Built all over the world and assembled like IKEA furniture!
The Boeing Aircraft I knew would NEVER have let this happen. “Boeing Aircraft Spec” was once a watchword for reliability and safety.
