First of all, spending more money on a better battery will not get you a longer lasting battery.
Having a warrantee is not a guarantee that you will not have problems with the battery.
If your battery has been draining to a low level, then you need to take the time to keep an eye on the battery. To start, check the battery voltage WEEKLY with a meter. If you ever find that it is somewhat low, then connect the car when you don't use it to a "battery tender" trickle charger. Or connect a small solar panel on the dashboard, which will keep your batterY in top tip shape.
There are so many types of drivers in this world, that do so many bad things to batteries, that this is the best procedure to follow for all people concerned with their battery.
Nubo provided an excellent response, so I will not go over all of that again.
I would expect a battery only three years old, in your climate, to still be working well, especially if properly maintained. Heat is very hard on batteries, and to get almost five years out of one here in the desert is doing quite well. I got the car at a little over two years old. All six cells in the battery were low on fluid. I topped it off with distilled water, checked it periodically, and got another two and half years out of it. Without driving regularly, and running a charge cycle every day this summer, the battery would not keep a voltage level high enough to keep the TCU happy. Pulling the fuse to do a TCU reset every few weeks gets annoying. I found a good battery, with a good warranty, at a price I was willing to pay, and did the replacement so I don't have to worry about the battery, TCU, or if the car is going to start when I need to go somewhere.
No, having a warranty does not guarantee there will be no problems with the battery. It does provide some peace of mind knowing that I can get it replaced for free if it fails within the warranty period. It does have a warranty one year longer that every other battery I looked at, and the sale price brought it down close to the pricing for a standard auto battery. Knowing what heat, and the Leaf Charging Algorithm, does to batteries, there is a good chance it will be replaced for free during year four, unless it truly is a 'premium' battery.
