Other Levo SL gen2 losing 3-5 pct battery while turned off

[ah1]

I've seen on occasion that the SL parked at garage and turned off would lose a few batt percent overnight. It won't keep losing them - so it's between 3 to 5 pct but then it stops losing them, even if the bike sits idle for long. I'm certain this is happening and certain that the bike is turned off. It doesn't happen all the time, but can happen both when the bike is fully charged and when it is not. The temperature hasn't dropped below 42 degrees when I've observed this.
I did call Specialized support and they thought it's probably the cold weather, but I'm wondering if this is happening to others and maybe in warmer temps.
Thanks!

Probably a leak, i would put a bucket under the bike to safe the electricity and then you won’t waste any

I have noticed that the number of miles left as declared by my display when I finish a ride is always less that the number of miles declared to be available by the time I get home. You are losing, I am gaining. Do you think it might just be the meters that we are using? After all, where does your energy go and where does mine come from?

It happened to mine turbo levo gen3, but it was 1-2%, I didn't pay much attention to it but thought it was due to temperature difference since it was cold outside

This may be due to the fact that after riding the battery is warm and shows too high values. When the battery cools down, it will show different values.

That's a good point, but this also happens to me after charging it (but still it could be warm while charging)

Yeah my sl does this. I suspect perhaps the fullpower bike does also, but that has the blue bar tcu so I wouldn't notice.
I wouldn't expect it to lose any % overnight after a full charge though.

How to Avoid Self-discharge When Fully Charged?​

If you want to avoid your lithium-ion batteries self-discharging when fully charged, then you should avoid fully charging them. If you charge your batteries up to only 90-95% of their capacity, then they won’t self-discharge as much. This is because at this charge level, the batteries won’t break down as much due to overcharging. This is something you should keep in mind when charging your batteries.

However,
it is important to note that lithium-ion batteries self-discharge even when they are not fully charged. This means that it is better to charge your batteries to only 90-95% of their capacity instead of fully charging them and letting them self-discharge to 10%.

​

Is There Any Way to Stop Self-discharge from Happening?​

The short answer is no.
Self-discharge is a natural process that happens in all types of rechargeable batteries. There is no way to stop it from happening.
However, there are some steps you can take to limit its impact. The first thing you can do is to charge your batteries to only 90-95% of their capacity. This will reduce the amount of self-discharge that happens while they are fully charged. Another thing you can do is to store your batteries at a voltage below 3.6V. This will prevent them from losing too much charge over time. You can also keep your batteries in a cool place like in your car’s glove box. Doing this will reduce the impact of self-discharge during the hot summer months.

--> only charge to full if you want to use the bike when you remove the plug...

I can confirm that this is the main reason!
Mine (SL) do this very frequently.
