Dell XPS 15 9560 Battery Swap 97 to 56 watt

Has any one tried changing the 97 Watt battery for a 56 Watt battery on the 9560 XPS 15 ?

I wanted the space with my UHD version which came with a 97 watt battery for the second hard drive,I have bought and tried 2 different 56 watt batteries that were supposed to be compatible with the 9550/9560 but I get an error when booting up saying it is not a genuine Dell battery and will not charge.

So just trying to see if I been stung twice with a knock off battery, or if the laptop will only work with a specific 56 watt battery.

Does anyone have the dell part number (that is on the 56 watt battery) from the 9560

thanks
Dave

 

Might be worth you posting in the battery swap thread on here, it will be several pages away but I am sure someone has a link for it. Normally people want the larger battery so you stand a good chance swapping for a smaller one with the HDD caddy included

 

You will likely need to disect and transplant the right part of the battery monitoring and embedded processor circuitry to the other battery if you want it to work. The problem with that though would be that it probably would try overcharging the smaller battery since it thinks it's the full sized one at that point. In that case, you would either need to transplant the critical chip's firmware from the larger battery to the smaller battery, mod the smaller battery's firmware to contain the signature as if it were the larger battery, or possibly just mod the BIOS. Unless I'm completely mistaken and it can be achieved at the software level via a custom driver installation/mod within Windows.

I'm interested to hear more if someone knows for sure. I will try doing some searching later. It's been a long busy day.

 

I think you are mistaken. The battery capacity is coded in the chip in each battery. The BIOS reads this chip and the battery charging circuit behaves accordingly. Swapping a battery to a different capacity will not cause charge management problems.

As already noted by @GoNz0, there are people who are wanting to change from a lower to higher capacity battery and may be willing to do a swap.

Boy how I love learning about low level stuff. :]

Here is a handy primer outlining some core concepts of battery modding in relation to laptops:

For health & safety purposes, I would expect most simple Li-po batteries to have some simple circuits that independently monitor temperature and in/out current & voltage. But the specs change for larger & different batteries. Laptop monitoring schemes are more complex so you can't rely on basic circuits to work or to protect you.

So putting in a different capacity battery may not work as intended or work at all. If it works, you may be reducing the life of the battery significantly if the capacity is not automatically detected and adjusted for (etc.). Most importantly, you may be unintentionally bypassing some safety features; causing fire, injury or worse.

Finally, if you choose to try disect the battery, spend some time researching so you can determine if you are comfortable with the challenges and can mitigate the dangers.

 

For anyone interested in batteries and battery technology of all kinds, I highly recommend joining Endless Sphere and spending some time with them. They have some extremely knowledgeable people who know a lot about lithium technology. Their forums just got a facelift too.

They also have a Facebook group but it is mostly dominated by ebike stuff.

 

Hi Dave, I'd be willing to swap my genuine Dell 9560 56 Watt battery and 2nd hdd cage with you if you're interested? I don't need the 2nd drive bay and wouldn't mind the extra battery life. Just let me know...

Thanks drew

I already sold the 97 watt battery, thinking the 56 watt i had on order would work.
So now I have no battery lol

Have another battery on order which is supposed to be a compatible one H5H20 part #.

 

Just to close this one out I finally was able to get a 56 Watt battery that worked,

H5H20 5D91C battery for Dell XPS 15 9560 15-9560-D1845 XPS 15 2017 9560 was the proper part numbers that was not rejected by the BIOS.

I can also confirm that any other battery that is not specifically used in the 9560 IE batteries from the 9550 will not work in this laptop.

I tried 4 different batteries all promised to be compatible, they all had the RRCGW or equivalent part numbers and failed to work.

I ended up getting the battery from someone on eBay, Dell would not sell this battery to me they said they had none to sell.
