Re: Laptop battery exchange - again - now what?

Post by CarrotCake »

Hi all,

It really wasn't my attention to cause a topic with ranting back and forth.
Please don't do that on my behalf :|

I am happy I started this topic as, apparently, it is a topic that is interesting enough to have a discussion about.
But I don't really have come a lot closer to a definitive answer, as there seems to be a lack of consensus about the best approach...

I do not know if I can check whether my (or original OEM) battery has a BMS, but given it's relatively new, ánd I come across references of BMS in HP batteries in general, I'm going to assume, for now, perhaps mistakenly so, that (at least an original) battery does have a BMS integrated.

If the BMS performs as designed, which seems a reasonable assumption, I should trust the BMS does the best job in charging the battery.

So what I'm going to do is that I'll keep it on charger if possible, but I will not carry around an extension cord for that purpose :)
On the other hand, the idea of having a laptop instead of a desktop is also about portability, so I will use the battery of course when I'm not able to charge.
But I will take care that I will not try to let the battery deplete too far, even when the BMS should protect the battery.

And still my Lenovo batteries lost over half their capacity in three or four years.
Depending on use, that's not atypical.

OK, a small addition to my initial question...

I'm typing on the laptop right now, and it's sitting at 0% charge for at least 10 mins already (and no, I don't have it plugged in :mrgreen: ).
So, maybe, my battery isn't that bad, but the notification of the actual residual power is wrong. I never let it run this low, it never shut down b/c of an empty battery that is.

I'm going to leave it running until dead, for now, and see what that brings... I know that in Windows there was some procedure to calibrate a battery, I don't know if Linux Mint has something similar??

Your laptop firmware handles that readout calibration element and depleting the battery entirely then charging it to 100% should help but don't do it too often.

I haven't done this even once I think - it is purely coincidental that this is happening now.
Maybe this solves my issue anyway :)

Possibly, there's more about manual battery calibration on the HP website.

Just wanted to post a small update...

Apparently, indeed the calibration of the battery is off.
I have now done two complete cycles of full charge and complete discharge -- meaning I don't attach the charger and let de battery drain until <5%, then I shutdown Mint and enter the BIOS until the laptop is completely out of juice.

Before I did this, TLPUI reported a battery capacity of 38% of designed specs; after the first cycle it went up to 55%, and now, after the 2nd cycle, it went up again to 68%. Of course, I don't think the battery itself gets a higher capacity; I just think it now better shows the actual capacity/level.
I will do this some more times to get it back >80% or until the percentage doesn't change that much anymore. I reckon that when these percentages are closer to reality, the actual run time until the percentage in Mint shows <20% will be a lot better as well.

I might not be any help but I just order from Amazon depending on reviews. I always leave the laptop plugged in.
