Could be battery or charging system. Good idea on not guessing and replacing perfectly-working parts with brand-new perfectly working parts. Because nothing will change. You'll want to do some diagnoses and troubleshooting to positively identify the problem 1st.

Do the following:

1. measure battery's voltage with everything OFF
2. measure battery voltage during cranking.

These numbers will be important clue on narrowing down area to look at next.

 

How is the corrosion on the battery cables?
