Our take on the Granatelli Motor Sports Sure Start Smart

by Dave Delamere

Avoid the dead battery

You get in the car and turn the key or push the button...and nothing. So, you're calling a tow truck or looking for jumper cables. The Sure Start Smart battery saver system from Granatelli Motor Sports eliminates this headache by monitoring the current drawn from your battery. When it senses a voltage drop below 11.8 volts for more than 30 seconds, like when you leave your headlights on, it cuts that current off so you have enough battery power to start your vehicle.

Not a one-trick pony

Not only can you save your battery power, the Sure Start Smart can also work as an anti-theft device. Push the button on the included wireless remote, and you've disengaged your battery so a car thief can't start your vehicle. Want to show off your new Crutchfield audio system without the engine running? You can turn the Sure Start Smart off and let the current flow without disruption.

A little black box that's green

When the Sure Start Smart does its thing, you and the environment benefit. This battery saver system lengthens the life your battery. That means fewer car batteries going to the landfills and less money you're spending on replacement batteries.

Features

Sure Start Smart Battery System: The Granatelli Sure Start Smart Battery System is a simple device intended to prevent Automotive-grade batteries from being killed do to unwanted or unsuspected current draw. The Granatelli Sure Start Smart Battery System monitors your vehicle's battery 24/7. If the Granatelli Sure Start Smart Battery System ever detects an excessive drain on the battery that may prevent you from starting your vehicle, the device automatically isolates your battery from the electrical current draw to ensure you will have at minimum 11.8 volts in your battery when you need it most. If it ever detects the vehicle's battery power falling below the required level to start the engine, its advanced micro technology processing system automatically isolates the battery from the vehicle's electrical system to prevent further drainage. When your vehicle needs to be started, a simple push of the reset button or remote re-engages your battery and power is restored.

Dual Remote Controls: Using the two supplied remote controls, the Sure Start Smarty Battery System can act as an anti-theft device by disconnecting and reconnecting power by choice. The remotes can also be used to reestablish power after draining.

Installation: The Sure Start Smarty Battery System is installed on the positive (+) battery post with the provided post clamp. The male spade-connector end of the attached black ground wire is fastened to the negative (-) post clamp bolt. The battery location and position differ in various vehicles. With the supplied accessories, you can mount the Sure Start Smart Battery System on virtually any vehicle's battery using a top mount, side mount, or chassis mount configuration.

Current Specifications:

  • Operation Current Consumption: 10 milliamps
  • Disconnect Current Connection: 3.5 milliamps
  • Maximum Peak Amperage: 1100 amps
  • Continuous Amp Capacity: 250 amps
  • Disconnect Voltage Threshold: 11.8V on 30 sec. timer

Operation Temperature Range: -60°F (-51°C) to 200°F (90°C)

Important Note: Before installing the Sure Start Smart Battery System, be sure the vehicle's battery is holding proper charge. If the batter is not holding the minimum charge, it may be at or near its life cycle and should be replaced. The Sure Start Smart Battery System is designed to protect a new battery or properly functioning battery. It cannot restore or repair a damaged battery. If the vehicle's battery shows signs of physical damage such as swelling, leaking, or cracking, replace the battery before installing the Sure Start Smart Battery System. When running diagnostics or jump-starting the vehicle, turn the Sure Start Smart Battery System to the "Off" position.

Sure Start

Crutchfield Customer Review (What's this?)
 
I bought this thing as a work-around brought on by an electrical draw caused by the instrument cluster in my 1992 Corrado SLC. It works like a charm. Yet I'm not sure what the long term use will be because it *seems* to shut down the car's old computer and forces it to reboot in a way it wasn't designed.

It works, bottom line. This little thing was the line in the sand between keeping my beloved car and getting a new one. I'm keeping it. :)

Thumbs up. It's the remedy to uncureable battery draws. $ well spent.

Pros:
Problem solved. No more dead battery. And it prevents thefts!
Cons:
VW pros installed in incorrectly and then fixed, not as easy to install as is made out. It was the mounting.
