Hi @SzymonD,

Welcome to the HP Support Forums! It is a great place to find the help you need, from other users, HP experts, and other support personnel. I understand you wish to disable the battery charge function. I will be glad to help you.

I do not know why anyone would wish to do this. Lithium-ion battery work best with 60% or more charge.  Any time the charge get below 10% it shorten the life of the battery. There is not and will not be an option to disable the battery change with lithium-ion batteries.

I also have this question.

My laptop is almost always connected to the mains. The charger maintains the battery at 100% almost all the time. As per the link from battery university that you had provided, please look at the table 4, given below for reference.

At 100% battery charge, at 4.20V, available stored energy is 100%, but the no. of discharge cycles is only 300-500.

Whereas at 60% battery charge, at 3.90V, available stored energy is only 60%, but the no. of discharge cycles is only 2400-4000. Needless to say, maintaining the battery at 60% charge, gives a life that is 8 times higher. Even if you take into account the reduced capacity (not applicable for the 'always mains connected user' who is not worried about reduced capacity!) that works out to 1440-2400, still a 5 times greater no. of cycles.

So, ideally, we should have the option to stop charging the battery at levels that can be set by the user, beyond which only the laptop should be powered and the battery charging stopped.

So the option of how much to charge the battery to the user is a great value for getting the max. out of the batteries.

PS : Sorry, the html formatting of the table (yes, it was a table) got completely messed up by my cut and paste, and please refer to the original linked page in battery university.

I believe the requirement to manage battery charging level is apparent to anyone who has actually read the linked battery university article. There is also this one useful paper on battery lifetime.

It is 2019, I own higher end HP laptop Elitebook 850 G4 and there is still no option to manage battery charging levels.

Actually, there is one - my next laptop will not be HP for sure.
