Will this work on E5420

I'm sorry I cannot answer this question for you directly. You should log in to the dell.com website go to the support page & enter the serial # of your machine. From there you will be able to retrieve a list of components or a spec sheet....that will lead you to the correct CMOS battery. I did that & I am very pleased with the battery replacement I purchased. My machine is NOT an E5420. Good luck.

Does this battery fit a Dell M3800 Precision laptop?

I appears from descriptions that the CMOS battery which fits Dell Latitude E6420 also fits Precision M3800. A search for it should show pictures & description should give number of pins & voltage.

Will this fit a a 2014 dell e6400 latitude? is it the correct connector?

Yes,it fits for E6400 all year models.

Is this cmos battery ok for a dell precision m6300 ?

This is a three wire battery - generally for older systems. Physically check the motherboard in the M6300 to see how many wires its battery has.
