Reply to "Battery Choice"

Battery life depends on other factors in addition to the manufacture. The charge rate/current is critical, over and under charging especially bad and very possible with the crappy regulator that was used in the Pantera. When the AMP meter is shorted as some owners do, there is no indication of current direction until it's too late.
Temperature extremes, heat is worse than cold, the best place for the battery is the original position. This battery design has low self discharge properties or low leakage current which is why it does not need to be on trickle charger over long period of disuse. The battery in the picture is 5 years old, sits all winter never charged for starting in the spring. Some of the electronics in this Pantera consume small amounts of current all the time and still no problems. Smaller and lighter about 1/2 the weight of conventional batteries. It would be better if it was black!
