BikeMaster TruGel batteries are a gel electrolyte battery designed to have a much longer storage life than a traditional battery. They resist vibration and impact, which can damage regular wet batteries. BikeMaster says TruGel batteries work better at lower and higher temperatures and won’t leak like a wet battery, even when the case is cracked. The TruGel battery can be installed at any angle, and has a lifespan that can be up to twice that of a standard wet battery and will not sulfate like a wet battery. TruGel batteries offer a two-year manufacturer’s warranty.
