LOL, yeah thats what the asshat said about my truck. I went to advance auto, the cat behind the bar said whoa...your battery is a very expensive one! I said oh yeah...why? He said cause it was some kind of special battery and I cracked up. Then I went to wal mart and paid less than $40. I will go out tomorrow and check, reciept is still on the side of the battery. A battery is a battery, as long as you dont need anything special, or have a huge drain on it, then you will be fine. Red tops, yellow tops, all those are 12 volts just like any other battery. CCA, and CA are what matter on any battery. And unless you plan on taking your truck into the lake you dont need a damn deep cycle battery. ONLY way i could understand it is if you have a huge and i mean huge power system drain. meaning aftermarket lights like five at least, a huge amp, aftermarket head unit, and things like that. Only then if you use those for periods without the truck running! ONCE a truck is running, the alt provides all the power you need. Our stock alts. provide 100 AMPS. Theres no way you will ever need that much unless you really do some heavy mods to your ride. Batteries like those are made for people who go above and beyond...or decide to run their radios and lights or whatever without the engine running for extended periods. A normal battery will do just fine for anyone else. Oh, and yes....the red, yellow tops are of a sealed and un spillable type, so in a crash they cant leak. BUT if your in a crash bad enough to worry about leaking, your trucks probally gone anyways.
