Frequently Asked Questions

How to Find Your Dell Computer Model Number?

Look on Your Device.
Check the sticker on the bottom of your laptop or back of your desktop. Look for "Model" or "Service Tag".

Or Check on Your Screen (Windows)

How do I find my dell Precision 15 3560 laptop battery part number?

1>Power off your laptop and remove the battery. Check the battery label — look for DP/N, Dell P/N, or Part Number.

The part number is printed on the sticker/label on your original battery. Laptop model alone is not enough to confirm compatibility.

2>BIOS — press F2 → Battery Information.

3>Dell Support — enter the laptop’s Service Tag and check the battery parts.

Can I swap between RJ40G 15.2V 63WH replace WY9DX 11.4V 42WH?

NO, they are NOT interchangeable. RJ40G 15.2V ; WY9DX 11.4V. Different voltage & BMS circuit. Installing the wrong battery will fail to boot and may damage the motherboard.

(They share identical physical connector & mounting screw positions, so the battery can be physically installed. However, Dell does NOT officially support cross‑voltage swapping.

Many users reported they can boot and charge after installation, but a startup BIOS battery warning may pop‑up.

There are potential risks of abnormal charging, intermittent power‑drop.

We strongly recommend you replace with the exact same part‑number as your original battery.)

RJ40G and WY9DX , why can't they swap?

Same watt-hour, but different nominal voltage (RJ40G=15.2V; WY9DX=11.4V).

The motherboard charging circuit and pin assignment differ. Installing wrong PN will cause battery not detected or safety risk.
