What is the difference between a C2 battery and a C4 battery?

C2 and C4 batteries refer to different categories of military explosives, not conventional batteries. C2 is a type of plastic explosive with a lower detonation velocity and is often used for demolition and military applications. In contrast, C4 is a more advanced plastic explosive, featuring a higher detonation velocity and greater stability, making it more effective for a variety of military operations. Essentially, C4 is an improved version of C2, offering enhanced performance and versatility.
