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.

Any light set worth it's name has a standlight function that will keep
the lights on for 3-5 minutes. Walking pace is enough to get them going
again as well.

I have 4-5h of juice on the road bike. If that ever drops off it'll cost
me around $20 to replace the Li-Ion battery pack.
