Favero assioma battery change

I bought my uno favero and after 2 years the battery is not holding up . How can I change the battery?

You can’t.

The batteries are potted in waterproof material along with the electronics inside the pod. They cannot be replaced. The pod and spindle can be, however. It is abnormal that the batteries don’t hold charge after 2 years. I’d recommend contacting Assioma support


Yea I’ve had mine for a year and a half and no problems with keeping charge for over a month at a time. What does “not holding up” mean?

It means that if I charge today I will work for 3 days and than I have to charge again

I would reach out to Assioma, i don’t remember the warranty declaration, but I’ve had mine for 2 years now and mine hold up just fine. Maybe you have a bad one, or something. I will say, I don’t top mine off very often, only when needed…usually at least half way discharged…but would recharge before a big/important race/ride or something. Same with my Di2. Good luck, hate that!

I wonder if they’re somehow not going into sleep mode and constantly searching for signal or are stuck paired to a device. The lights should stop blinking after a few minutes sitting idle anyway even if I stop at a cafe they will go to sleep. Do your lights blink all the time?


I’d say that this is more likely a firmware glitch or a hardware fault. I believe favero state that the battery should be good for 10000 charge cycles or something silly.

Reach out to support but I’d try just resetting them and making sure they have the latest firmware first.


Touch wood my Favero Be Pro S still lasts for weeks after its charge and its probably similar technology thats in the Assiomoa’s; I reckon you’re right, definitely the first thing for the OP to do.
