something is definitely wrong

2 days ago, my starting up sounded kinda slow, so i thot it was a starter problem

1 day ago, my car died, and got jumper cables and had a boost n my car was running, i drove everywhere to try to recharge my battery n thot evertyhing was ok

today, my car doesn't even honk and there is absolutely no power.

is it my battery?? or my alternator??

a) if its my battery, what battery should i replace it with?

b) what can i do about my alternator?

 

Is there any parts stores local to you? They will check both the bat/alt free. You can check if you have a meter to see if juice is being supplied back to the battery.
One piece of advice. In cold weather and short days, make certain the alt belt is tight. If too loose, over a period of time with heater, defrosters, lights on longer, the battery will run down if the belt slips around the alt pulley. The pulley just won't turn as fast as it should.
Once you have them tested, you will know what to look for, or at least were to look.
Could even have a drain on the battery when ignition off.
