The battery for this system is the 84 WHr 6-cell.

Later model(s) used the 97 WHr battery -- which most likely won't work (and if you decide to try, be sure you understand any restocking charges your reseller will apply in the event of a return).

Further, you're better off with an OEM battery (above) - NOT a third party battery.  

Yes i heard the 97wh battery is for later models 9560 and 9570.  But i also heard ppl put that battery in a 9550 and it worked.  So i like to know if anyone here has done this or not.  Now would it have something to do with bios not recognizing it or something like that?  Thing is for me... i never did anything with bios ever... and i had this computer for many years already.  

Someone else mentioned they put a 97wh battery in and it works but said they were from new zealand and bought it from a local supplier there.  So if its the same model number... then it would work?

Just realize that what you've heard is likely to be unsubtantiated, so be sure that if you decide to try, you understand your seller's restocking charge policy.  Very few vendors will take back a non-defective battery, and even among those that do, there's often a 15-20% restocking charge.  There's a very high probability a battery designed for a newer system will not function properly.

Yes im aware of a restocking fee etc.  But since i know many ppl here had the 9550... to see if they ever used a 97wh and if it worked or not.

6GTPY   97whr

Can any previous or current xps 9550 owners tell me if this 97wh battery with this model works or not with it?

Okay I like your opinion on this. I asked laptopbatteryexpress if the 97wh is compatible with the 9550. They told me it wasn't. I then said i looked at the reviews of the 97wh and one customer a while back said it worked with the 9550. They said it isn't compatible. I mentioned to the laptopbatteryexpress rep, I read online the 97wh model 6GTPY works with the 9550 because I read on forum other users said it does but also... on ebay... one popular seller sell the exact model for the 9550 and even the seller of that battery on ebay tells me its compatible with the 9550 since i see lot of people bought from that seller. This is what he tells me The xps 15 9550 uses many different batteries and are not interchangeable.

The battery used varies based on when it was ordered and what configuration it shipped and NOT THE MODEL NUMBER ALONE. You can't go based on what other people used in theirs, you need to go based on what your laptop has in it which is a 4GVGH 84h battery. Now can others confirm this statement? I never heard of that before but that sounds very interesting. So the model number is not what you are suppose to look at but what configuration the battery was shipped in? I have never heard of that ever.

Thanks.

If you want a known compatible battery, this is it

For all the other sellers, the vast majority of batteries they sell are not OEM - they're third party.  In those cases:  ask the sellers.

Okay i see parts people are legit.  But are those third party batteries almost always worst than the parts people one?  The laptopbatteryexpress seems pretty legit right?  But would it be foolish to buy it from there for only ten dollars cheaper than parts people?  Thats how much the price difference is only... like ten dollars.

So that is a no brainer get it from parts people vs laptopbatteryexpress for same battery for a ten dollar price difference?

You're essentially asking the same question each time:

"I've made up my mind I will use a 97 WHr battery in my system despite it being unsupported.  What I'm looking for is verification that my choice is correct".

No one can give you that -- and no, a $10 savings isn't worth taking a chance on a non-OEM battery.  Are all of them trash?  No.  Are most of them inferior to the original?  Yes.

Hey yeah i know the difference between parts people and laptopbattery express is only ten dollars.  But laptopbatteryexpress seems to have very good reviews... but them having the 97wh battery is what interest me the most.

But do you believe the customer service at laptopbatteryexpress is correct that it won'w work on my 9550 and their reasoning?

Hi, 

Could you tell me what is your decision?

I have a laptop XPS15 9570 purchased in Taiwan and the 56Wh battery(H5H20) is dying.

I purchased 3-party battery 6GTPY from canadalaptopbattery but the system couldn't charge this battery.

Then canadalaptopbattery send me 2nd battery (6GTPY) and same situation happen again!

I checked the BIOS and that 6GTPY could be detected but status was 0% for one day charging.

I need some suggestion from all of you, please. Thanks!

The question is, does the system recognize the AC adapter.  F2 at powerup to check.

If the adapter shows "unknown", the battery will not charge.

Hi, 

The system could detect the adapter(130W).

I have 2 adapters and the original genuine battery(H5H20) could be charged from 0% to 100%.

Thanks. 

To everyone inquiring about newer xps 9560 97whr 6GTPY working in our older 9550, which originally had 84whr 4GVGH (or 56whr if ditching the cute, out of touch second HDD/SSD)

   The 9560 battery will almost CERTAINLY WORK!
