Battery Brain - intelligence for your battery

Remember when your car (or truck or SUV) battery first died because you left the headlights on or, in more modern times, left the cell phone charging in the vehicle’s cigarette lighter and you forgot about it? Smart Energy Solutions, Inc. now offers the Battery Brain, an aftermarket device that monitors the vehicle’s battery. When its systems detect the battery charge dipping below a certain point, it automatically cuts off the power to any device that may be draining the battery (e.g., cell phone).
Battery Brain works with any conventional lead-acid battery and uses the vehicle’s standard battery cables.
