It sounds like you need to figure out either or not it is in fact the battery that's bad and not the alternator, fuses and/or cables first. An FYI- When you purchase a battery there is something called a core charge. It's basically a disposal fee. So you're going to need to bring your non-changing battery with you to the parts store, or will be used as your core. If not they will charged you a core fee, which is refundable to you upon the return of your old battery. The same goes for the alternator as well. I hope this helps.
What you can do is take off the top caps refill with distilled to bottom edge of each cell put caps back on and if you have a 12 volt trickle charger, hook up to each post and let it charge over night, that's the same as battery restoration.
Before you start replacing things . . . figure out what's broken. Will the engine start from a jump start, and does it continue to run when there cables are removed? If not, you may need a new alternator. If the charging station is working correctly then you probably need a new battery.
You could get your battery tested
