Start by making sure the battery itself is good. If the battery is good, then you more than likely have a defective alternator. Any auto parts store can diagnose the problem.
If the question is how to check your alternator on a 2000 Honda accord is by starting your car and disconnect your battery if the car is still running for max 3 mins you know your alternator is good.
Only if the battery fails the load test.
It means something is wrong with your charging system. Can be a loose of corroded battery cable, defective alternator or a battery with a dead short.
If you are 100% sure the battery and alternator are good and the battery is loosing it's charge then something is on pulling power from the battery. Can be any light or any relay on the vehicle.
Check for a bad ground. Follow the ground cable from the battery to the car's frame. If there is corrosion, remove the bolt, clean the area, and reattach.
Your distributor might need to be replaced. Answer #2: Check for loose or corroded cable connections at the battery posts; also, a loose belt could be the problem.

Not a good sign, This could mean that your charging system (alternator) isn't doing its job. If you have problems starting the car due to not enough battery power, then check your battery to see if it is holding the charge. If after a while that you had to boost or jumpstart your battery your car gradually dies then check your alternator to see if it is putting out charge to the battery.
I would suggest the alternator as I just went throw the same situation Changed the battery first but the problem happened again in the middle of a long trip and the alternator was only 3 months old it was defective.
