A student purchases a 3.6 V lithium-ion battery, having a capacity of 920.0 mA×hours for a price of $49.90. Determine the cost of the energy purchased by the student in $/MJ

So I solved the problem and got $4,185.12/ MJ. But this just seems wrong! I'd appreciate it if you could check my math and let me know what I'm missing.

49.9/battery x battery/920 mA×hr x 1000 mA/A x A/C/s X hr/3600sec x C/3.6 J x 10⁶J/MJ

Doesn't have to be right, but looks OK to me.
