This confirms the observation that the Boris buses seem to run noisily on
diesel most of the time.

It's a pity that the Grauniad has angled this as a political
Wolmar-for-mayor story, though: whatever Boris's faults, technical problems
with a battery pack can hardly be blamed on him. But I wonder why the Boris
bus batteries are seemingly more troublesome than those in other hybrid
buses?

I doubt it's the batteries themselves, but it's quite plausible the
charging/discharging electronics wasn't quite right and this could have
shortened the life of the batteries (both the life each day, and the
number of days).
