Okay, a little battery 101. First of all, you can test your battery with a voltmeter. Interpert the readings as such:
12.0 = Dead battery
12.2 = 25% charge
12.4 = 50% charge
12.6 = 75% charge
12.8 = 100% charge
However, this will not tell you the load capacity of the battery. For this you need a load tester which any parts store should be able to do for you for free.
Also, you can get a hydrometer and test the specific gravity of each cell, and see if you have a weak cell. There are more tests, but if you havent found if the battery is good or not by this time, it is too late.
But, if you just had electrical work done, I would first check to make sure the ground connections are still good. That is the problem in about 70% of the drivability issues that I find. Make sure the connections on the battery are tight and clear of corrosion (including under the terminal clamps)
Hope it helps
