PriorityStart! Intelligent, Automatic Battery Isolation

The Low Cost Solution to Flat Batteries (suitable for engines with up to 1000 amps starting current)

Higher specification charging systems, dual batteries and split charging systems help, at a cost, to maintain battery charge whilst high current equipment is operating and the engine running.

However a flat battery is far from a thing of the past as a result of electrical equipment being left on while the engine is switched off, operator error, or parasitic currents! And many vehicles do not lend themselves to the application of such expensive and complicated battery management systems.

Now, PriorityStart provides a low cost solution to flat batteries either stand-alone or as a belt and braces solution alongside higher specification charging systems.

Accidental discharging of vehicle batteries results in

Lack of vehicle availability leading to customer complaints, unproductive operators/drivers
Call-out costs
Potentially battery-damaging recharging practices
Use of dangerous or damaging jump leads
Inconvenience and irritation to all concerned
Irreversible damage to the battery destroying its ability to be fully recharged.
Accelerated battery failure with associated costs
Higher maintenance costs

Technical Summary

PriorityStart! is a patented heavy duty electro-mechanical device (handles up to 1000 amps) that disconnects and reconnects the battery when required. To do so it uses not a relay but a bi-directional motor geared to provide a 35 kg clamping force on its internal contacts resulting in a very low resistance and high reliability. This clamping force is superior to a normal battery post to cable connection.

It passively monitors battery voltage and detects a drain due to equipment being left on without the engine running. When the battery voltage has been beneath a predefined threshold for more than one minute then the battery is automatically disconnected.

Patented circuitry inhibits undesired disconnection whilst the engine is running or hazard lights flashing

The unit then automatically reconnects the battery - simply operate a light switch, push on the brake pedal or turn the key! No buttons or switches, just START!

PriorityStart! does not disconnect and reconnect each time the vehicle is started, only when a load has been left on when the key is turned off.

Its housing is moulded polypropylene, the same material as a battery case, and weighs approximately 0.5 kg.

Temperature range -40 to +85 centigrade
