i went to start my truck this morning and i heard some popping noise from my battery and now my truck wont start and it shows that the batter is low like beyond the point to where its enough juice to crank the starter so i put it on the charger and now the buzzer that comes on when you open the door comes on it makes a weird like its dieing noise and when you trun the key it clicks from the passenger side fo the truck but nothing happens it doesnt turn over or anything what is going on!!!!??????

Put a volt meter on the battery when you are trying to crank the engine over. Likely it is dropping very low under load. Or take the battery to an auto parts store for a load test. Might also check the battery connections and look for corrosion.

there is no corrosion now its not clicking in the truck its near the fuse box under the hood and when i turn the key to start it i hear a humming sound coming from under the driver side of the truck

4Crawler's advice is correct. Start there and post up your results.

it was my battery i have a 1997 ford explore in the backyard with the 5.0L and i pulled that battery and yea it runs smooth i took my old battery to advance and they said it wouldnt hold a charge it had about 10.5 volts and that was it and i have one more question when i put the 5.0L battery in my yota the battery gauge is higher almost touching the 18 mark is that a good thing or bad?

You might check the charging voltage with an accurate volt meter, but if that new battery is somewhat discharged, then the charging voltage will be high for a while then drop back to around 13.6 volts or so.

but its not a big deal that its a bigger battery?

Assuming it is a 12 volt battery, a 12 volt battery is 12 volts no matter how big or small it is. Only difference is that a larger battery often has more reserve capacity and/or cranking amps.

you need to check the charging voltage with an accurate voltmeter to verify it is not any more than around 14.2-14.7 with the engine running. anything higher than that is going to overcharge the battery, boil off the electrolyte and damage the battery and can damage other parts of the electrical system of the truck.
for the record, my 91 settles at about 14.5 within a few minutes of starting, and my 88 settles about about 14.3
