This battery has served us well in a pickup for over 10 years now, having gotten a semi-regular dosage of frequency pulsing over the years. With the new 2x4-inch SD-1200 siliconed to the battery, it may well stay functional for a few more years. While we used silicone, tie-wrapping the unit to the battery cables (or something else within reach of the 17-inch-long wires) also works well. Since the Canadus is waterproof and the indicator light largely irrelevant, there are several suitable methods of installation in just about any vehicle.
