[V8] OEM vs Aftermarket batteries

[S_Matus]

I think that all batteries will perform well in all vehicles.  Group 49 batteries are a class of battery that is rarely poorly made. I would not say that about some of the aftermarket batts for the toyo-niss-onda imports,
 
If you Charging System is 100% when you install that new battery I think you should be good for at least 4-7 years.  As long as you mitigate the extremes to the battery it will give you many years of service.
 
The Ememies of our power sources are:
- Extreme heat or cold
- Improper charging (In the car or out, just watch those inexpensive chargers they can cook a battery)
- Electrolyte level (yes Distilled water is a must, but if you can find De-ionized water it is better yet)
- Draining the battery below 12 Volts or completely dead (No Voltage)
- Sulphation is a common death to a battery

I'll address the sulphation statement.  Through the normal Charging/Dis-Charging cycle of a battery the plates will sulphate.  I think this has to do with incomplete charging cycles (Not charging the battery until it is 100% charged).  You can buy De-Sulphation Chargers that will correct the condition. They send a high-frequency pulse through the battery to dissipate the sulphation. To do it properly, you must completely charge the battery with a "zero-Delta-V" charger and then put on the De-suplhation charger. You can directly put the De-sulphation charger on the battery, but it will take a lot longer to begin the de-sulphation cycle.  You should leave the De-sulphation charger on the battery for as many days as possible.  I usually try for a week at a time. I repeat this every Spring and Fall.
 
the De-sulphation chargers are available from www.batterymart.com
