I certainly did offer contrasting data. The lower reserve capacity and the higher price of the Optimas and other glass mat batteries. Also the AGMs overall have warranties no better, and often worse then the conventional batteries. AGMs got dropped by many installers of battery banks because their warranties are too short to qualify for most incentive programs. Most state and Federal programs require a 5 year warranty.
Is there some other nebulous element here I'm missing? Reserve capacity is the overall most important factory in starting a tractor in cold weather - unless it's parked in a heated garage or hooked to an electric block heater.
I do a fair amount of work with large battery banks. If you own a battery bank, or even a collection of tractors and plan on keep them going for a long time - your price of batteries can be figured as a cost-by-month. Figure in the up-front cost, the power available, along with the expected or average life span - and that tells the story.
Last time I figured (I do it about once a year due to price changes) it goes like this.
Flooded lead acid battery - medium price range with medium warranty. 900 amp hours costs $9.50 per month.
Flooded lead acid battery - premium price with extended warranty (10 year average life). 1,120 amp hours for $8.30 per month.
