Can this battery fit on the ldx120c model?

Yes. I see ldx120c is a 20-Volt MAX Lithium-Ion Cordless Drill/Driver, our this battery is a 20v lithium battery. So they can work with each.

Will the 2.0 work with an replace the 1.5?

Sure, if they are 20v black & decker 20v lithium battery. They are compatiable with each.

Dear Seller, 4AH sounds like nonsense. What is the configuration and type of battery cells inside this battery pack?

I do not know what the inside configuration is. I have these batteries. They last longer than any of the other batteries that I have. Bought 2 and they worked so well I bought 2 more.

will this work on B&D weed eaters?

They work just fine in my Black & Decker LST 300 Type 1 string trimmer. They are 20 volt.
