Query: Select non oem/dell replacement parts at your peril

Although these replacement batteries and adapters may work for a while, many DELL laptops aren't compatable with aftermarket accessories, especially power adapters and batteries.If you plan on keeping your laptop, get OEM at the best price points. My D-600 operating system repeatedly 'errored' some of these aftermarket components as being out of spec.
