meanwhile, production rate is about what, 40 a month? at least 120 ac stored somewhere waiting for the temp fix…
Current production is four frames at Everett and one at Charleston per month. The plan is/was to be at 10 per month across both FALs by End-Of-Year.

"No battery-related incidents occurred before January 2013, when the airplane experienced two events."
Replacing over 100 of them so far is certainly an issue with the design and viability of the design.
The 100 replacements were due to the battery shutting down due to being over-discharged. As over-discharging can induce thermal runway, the system is designed to shut the battery down when it reaches a specific level of charge. So in these cases, the battery safety systems were operating as designed.
