Charging

Well … it’s safe (in terms of possible danger) but not recommended to avoid battery wear

@sartoric
what I never know in general: do manufacturers control these limits?
I mean if it is wearing the battery so much a company that strives for sustainability should charge and use within these limits, no?

@freeheeler That’s a good point. I never really understood the 80% thing, from the point of view of if its that impactful, shouldn’t everything be set to stop at 80% charge out of the box, with an option to charge to 100% if you plan a big outing away from a charging source, no?

@freeheeler if 20 - 80% is beneficial for battery life, I’d like to know it from Suunto as an official statement. I see no need to go over 80% with S9PP with its battery capacity and quick charge.

@freeheeler said in Charging:

I mean if it is wearing the battery so much

In fact I wouldn’t say “so much” but “more”
That said, if you don’t fully charge it, you won’t be able to squeeze all the juice you need out of it

You should be able to choose (like you can do with some mobile phone) to stop at 80%, but maybe you won’t increase the longevity that much to justify additional hardware/software management, considering you don’t need to charge it frequently.

After 5+ years of use without too much care my Spartan is still (touching wood) ok

… and we don’t know if that 100% we see refers to 100% battery capacity

this discussion is rather academic.
A state of the art LiIon battery used between 20% and 100% charge has like 1000 charging cycles before degrading significantly.
When only charged to 90% full this number is almost doubled to 2000 charging cycles.

As the Suunto 9 Peak Pro under normal conditions needs to be charged like once a week, it will last around 20 years with 20-100% charging.
This is long enough to not make me think about it.
If you are a “wrap TV remote into plastic bag” kind of person, then you might want to charge 20-80%. Otherwise just use it.

(me myself I charge whenever it fits into my daily routine - like during morning shower.)

@Egika but what if we wrap the watch into a plastic bag? Will it help?

@Łukasz-Szmigiel if you wrap it tight, it improves OHR performance
