CTEK says dedicated battery support equipment is best for the modern workshop

With almost 50 percent of all vehicles arriving in the workshop with a battery that needs attention, CTEK says it is important to ensure the battery is properly supported by dedicated battery support equipment.
“‘Battery Support’ (as distinct from charging) is vital for the supply of ‘clean’ constant voltage for vehicle diagnostics and programming,” CTEK Asia Pacific Director of Sales and Marketing, Robert Briggs, said.
“By opting to use a stand-alone battery charger, or not providing any sort of battery support at all, workshops are risking programming failures and damage to vehicle ECUs that can affect workshop efficiency, profitability and reputation.”
There are four key aspects to ensuring a battery is supported:
• Voltage specific: diagnostic work, flashing and reprogramming require a fixed voltage and ripple free current throughout. In fact, for many vehicles, a specified voltage is required across the vehicle system before it will even start communication with diagnostic and/or reprogramming equipment.
• Reaction: during diagnostic and especially flashing and reprogramming work there may be certain ‘spikes’ in power demands. In order to maintain constant voltage across vehicle systems, any battery support needs to react immediately to avoid voltage drop that can result in diagnostic or programming failure or damage to vehicle ECUs. CTEK says a standard battery charger/maintainer will not react quickly enough, as this is not what it is designed for.
• Using a battery charger: however smart a standard battery charger/maintainer is, it will be working on pre-programmed charging algorithms that will see voltage rise and fall to achieve optimum charge levels – good for charging but not so good when a constant voltage is required. This means that there may be certain times when battery voltage is above (and of course below) operating levels for diagnostic work, flashing and reprogramming.
• De-rating: battery support units deliver high levels of power over a relatively long period of time, and as a consequence they can generate a lot of heat – this can make a unit de-rate. De-rating is where the unit will reduce output levels and that’s because heat causes resistance, that in turn will cause the unit to reduce charge levels, and at really high temperatures reduce current output – this can affect the unit’s ability to maintain battery voltage.
CTEK says its PRO120 is an innovative, versatile and highly efficient 120A battery charger and power supply, designed around the needs of the modern workshop. With its variable yet extremely stable output, quick reaction times and integrated safety features, CTEK says the PRO120 will support the battery and protect the vehicle’s delicate electronic systems – without de-rating.
Whether you’re repairing a vehicle, testing electrical circuits, carrying out diagnostic procedures, flash programming ECUs or programming vehicle keys, CTEK states dedicated battery support is a vital activity often not fully appreciated for its importance in saving technician time and insuring against costly programming failures and preventing possible costly damage to the ECU.
