My battery health is increasing.

[Mike Boreham]

Coconut Battery says my battery health has steadily improved over past few months from 85% to 90%. See Attached.

In the same period System Profile has shown a similar increase.

Anyone surprised about this?

And what is with the two batteries? It has not had a battery change.

The charge level and temperature greatly influence the guessed battery life that coconutBattery shows. I wouldn't take those numbers as gospel - more like rough estimate. My experience with coconutBattery is that it can deviate at least 5% depending on several factors. Use it as a general rough estimator.

Thanks. Yes I agree and having used Coconut for many years I have seen variability and scatter. But my data is not showing scatter, it is showing a steady trend, which is why I am so surprised. It is consistent with the data from System Profile. When I got the machine (used) six months ago SP showed 89% and now it shows 93%. It spends nearly all the time indoors in my study where temperature is very consistent.

I have no idea about the usage it had in its first 30 months before I bought it, but maybe my usage has "exercised" the cells so as to cause some recovery.

Batteries don't recover. This is basic chemistry.

That is certainly true of non rechargeable batteries, but cycling rechargeable ones has long been a way of reconditioning (sometimes) rechargeables.
