I think I need a new battery, What do you people think? Options

Well, I pretty much have it down to the battery for my current problem. Here's the things that have been happening to me recently...........

- Car was parked and left running for about an hour, then I turned it off. When I went to turn it back on shorty afterwards, it started, but hesitated to do start.

- I had my hazard lights on with the car turned off for about a half hour and I turned her on and she hesitated to start.

- I left my lights on for about 20 min and it totally killed my battery.(Aren't lights
suppossed to last a bit longer than 20 min with the car off?)

It seems like I do alot of weird things to my car, but I drive fulltime for Domino's Pizza and I sometimes get back from a delivery and just leave my car running before I go back out for another one. Anyway, once the car is started up and I'm driving around, I have no power loses, so I would think that would eliminate the possibility of my alternator going. What do you guys think about this? Battery or Alternator?

By the way, what are some good batteries out there. I've had an Interstate battery ever since I bought the car and that would mean that it's been there for at least 110,000 miles. I've heard that Die Hard is pretty good too, but I've never bought a battery before. I'd appreciate some help from you guys. Thanks

Just go by any auto parts or battery place and have them load test it. usually doesnt cost anything. but if its been in for more than 3 years, just replace it anyway...not worth the trouble or the cost of having a mechanic check things out for an old $60 battery. if its not bad now, it will be soon... if you have access to a voltmeter, verify you have at least 12v with the car off and approx 14v with the car running, if you do, the charging system should be fine, if its under 11v with the car off, your battery is weak. most portable Bat load testers have a built-in voltmeter, so look at it running and off while it is hooked up (not while they have it under load)...
