Everything you want to know about Shocker Batteries, and then some.
Shocker batteries are explicitly developed for V-Twins and offered at a very competitive price. These factory-activated and sealed AGM-style batteries are assembled in a robust stock appearing ABS case with a matte black finish. The terminals are a flush mount design with dual connection points (14-amp models have one connection point) and captive internal nuts for a fumble-free installation.
The impressive list of features includes extra thick plates for extreme vibration resistance, a heat-sealed cover to protect against leakage and corrosion, and fully sealed posts. Independent laboratory testing parameters include high-rate discharge, ten-hour discharge, vibration, short circuit, and zero-degree Fahrenheit cold cranking amp tests. Also, these units were subject to extreme field-testing conditions during their development.
