Hi
I have the original Varia radar unit since it first came out, and the battery is starting to decline where I am only getting 2/3 hours use out of it now.
In the summer I am doing a few long rides (200+ miles) and would really like to have a unit that will be able to last c14 hours.
So.
Has anyone tried to replace the battery of the original radar unit
Or
Is the newer RTL515 battery life really 16 hours in daylight flash mode?
TIA
