My wife's Lezyne Deca 1500XXL stopped taking a charge, at all. Taking
it apart, I saw that the batteries were made in July 2015. Not too
good for it to stop working that soon.

Some of my bikes have dynamos that are 30 years old. They just keep
going and going and going...


Until you get to a red traffic light, to a stop sign or into a traffic
jam. The perfect spot at night to get hit by a car driver who didn't see
you because you were on the only unlit vehicle around.

AFAIK: dynamo lighting is illegal in the UK for exactly that reason.

I do not think so. It may be the case that turning across traffic at
night you don't wait in the middle of the road, but stand lights have long
solved that.

Looks like what I was told was either wrong or out of date - but I have been
warned that a backup battery may not make a dynamo ant less illegal.
