Also,,a new Battery often needs a Full Charge put on it.

Having just replaced the battery indicates that it is PROBABLY a good battery, but then you DO know that there are defective products on the market, right?
If the battery is known to be good, and the charging system is known to be within normal operational parameters (charge rate of > 14.3V @ idle), then the only thing left is what is termed a PARASITIC draw.
Something is causing a significant current draw from the battery when the car is just sitting.
Things to check…
1) Defective alarm or security system
2) Stereo or booster powered up with key off
3) Trunk or glove box light on (bad switches)
4) Defect in wiring causing some other device to be left on.

If you are going to attempt to repair it, connect a test light or meter to the system, and begin to remove the fuses, one at a time. Watch the light, and when you pull the fuse that controls the circuit that is causing the problem, the light will go out.

you need a new alternator and voltage regulator and have the battery charged.

How much will ignition coil install and brake bleed cost?

process of elimination,first check the condition of the battery terminals. then
alternator check. then
fuses and fuseable links. There are automotive part stores that will check some if not all of these things out for you. Let your fingers do the walking and call around ie...Pep Boys, Kragen, AutoZone. etc.....
