A couple of things:
Beg, borrow, steal a digital multi-tester. Set it on D.C. and check across the pos and neg terminals of the old batt. A fully charged batt is 12.66 V.
If you find the batt voltage low - check the water level in the batt. If low, (top of plates out of the water) -fill to within 1/2 " of the top using distilled or de-mineralized water only. Then try a charge.
Better yet - either take the new batt back and get one that will fit or - change the batt cable terminals, (usually $1.00 ea), so they will fit the new batt. If one cable is too short and the other is too long then you have to get a batt with the pos and neg terminals reversed.
When you get the vehicle started - check across the batt terminals with the meter. It should read 13.8 to 14.4 V, with all accessories ON, if the alternator is working.
