That was quite tedious, but now the results are in ..
Initially I was testing using "Steady High" to speed it up, but the results looked funny so I switched to my intended use - "Fast Flash" which is the daytime flash setting.
Edit: Time 'h' is time in hours until the light stops flashing.
My observations:
.
Both lights actually met their specs, unusual these days.
The Cherrybomb gets dimmer as the battery expires, but 1.2v and 1.5v look quite similar.
Li-ion really didn't perform well, I've no idea why. But I quite like the concept.
Alkaline batteries keep going a long time after they're not doing anything very useful.
EBL 1100 mAh NiMH are very good and really quite cheap: £1 each.
.
So my cunning plan is:
.
2x EBL 1100 mAh NiMH in the Cherrybomb
When front battery warning goes green recharge front and replace rear batteries
.
That gives me 24 hours runtime and 1.2 hours of full beam on the front lamp in emergencies.
BTW. There's an active r e d d i t group for batteries at

Update:
Front light is saying recharge me after 7 outings which is around 21 hours.
I'll take that as a win
