TI36X Pro—Replace the batteries or just get a new one?

RE: TI36X Pro—Replace the batteries or just get a new one?
Another item that I like about the TI30X Pro MathPrint is that an equation entered in ""table" as f(x) can be used in solve and in d/dx and in integral as f(x) instead of having to reenter the equation in those operations as required by the CASIO 991EX. This is also true with the 36X Pro. The 30X Pro MathPrint also allows the same with g(x). I mostly leave g(x) permanently defined as d(f(x))/dx in table so that I can find candidate locations of extremums of f(x) very quickly in table, and then use g(x)=0 in solve to find the extremum to a high degree of precision. I can then put g(x), f(x), and x on consecutive lines to have f'(x), f(x), and x labeled and displayed on consecutive lines.
