XPS 15 9575 Battery Electronics

Question

So I refuse to have to get another battery, just to maybe run into the same issue. As described before, my battery runs funny. When I calibrate it, I can get 57/74 mWh, which is more than acceptable for a 3 year old laptop that has not been used that much. However, upon discharging, the battery goes unpredicably from 30% to 7%, or 20 to 7%, and then it shows all the way down to 37/74 mWh, which is 50%. I would not mind this if that was the actual case, but if I run the battery down to 0%, it will still work for an hour or so. Obviously, the electronics are somewhat messed up, and I hope it is not programmed to act this way just so Dell can sell more batteries.

For some reason there is a 30% of battery hidden under 0% reporting by the system.

Any help with this? I have tried all the drivers. I know the article says some old Vega drivers can do that, but all of them do it.

Also, I am in Turkey currently. Any chance I can get a good deal on the new battery here? Hopefully, someone from the support can address the issue for me.

Tnx!

You need a new battery - simple as that. This is the part to search for.   https://www.parts-people.com/index.php?action=item&id=28062

Where is the best way to purchase a new battery, and what is the guarantee that it will not flake out like the originals. I do not live in USA, but I will be travelling there in 2 months. I will order the battery in advance, and have about 10 days to test it.

Should your link to parts-people web site be ok?

Thank you for all the suggestions.

The fact that no manufacturer will guarantee a battery more than 12 months is an indication that there is no guarantee a replacement battery will survive longer than three years - - batteries are consumables, in the same way the brake pads on your car are. The flip-side is that notebooks are designed around a three year life cycle -- the failure rates rise at that point, so there's no guarantee that the system won't give out before your next battery does.

3 years? yeah right...more 6-7. what exactly happens after 3 year? is it programmed to fail? that would be a serious accusation...

No, but as most businesses know, at the three year point components begin failing in larger numbers. That's why most businesses replace notebooks on exactly that cycle - three years.

There is a design life built into everything you buy - automobiles, appliances and computers. The design life of a notebook is three years. Some will last much longer, but many will fail before even that point is reached, and the rate of failure jumps appreciably after that three year design life time point.

Some system manufacturers (Apple being the largest) won't permit buyers to purchase extended warranties longer than three years. Dell allows four -- but it does give you an idea of the expectations of the system seller. Price a year's warranty extension on a 2-3 year old notebook -- you'll see.

I might just sell the computer here in Europe, and buy a new one in USA. I can almost get 70-80% of the price that I have purchased it for 3 years ago. Dell pricing in EU is terrible...

Well, I got a brand new battery, and guess what? When I popped it in it said 97% and at about 25% it went down to 6% again, and upon reboting, the battery health went down to 92%. So same exact cycle is happening with the brand new battery. The computer is basically faulty, but they refuse to admit it.
