If a new and better battery does not fix the problem then you have a parasitic battery drain. It is also possible you bought a bad battery. I would return it and get another one. Bud is wrong. You can put an aftermarket battery but it does have to be the correct size (obviously).

Size 25 is OE size; 34 squeezes in nicely and can offer higher CCA for +$9 at COSTCO. The 25 is just fine.
