Frequently Asked Questions

How does the VEES and HD648 Technology work?
VEES and HD648 Green Energy use a patented process that eliminates electrical system faults due to voltage losses created by battery plate degradation as a result of batteries simply being in service. VEES and HD648 reverse degradation allowing the battery to power the electrical system at full voltage.

What are the benefits of using VEES and HD648 Technology?
An efficient electrical system working within design parameters (full voltage), results in fewer battery replacements, a decrease in maintenance costs, better fuel efficiency and a reduction to your carbon footprint. It helps you save money, save time and gives you reliability and peace of mind.

How are VEES and HD648 Technology different to other Pulse products?
The best way to answer this question is to say that in order to be able to sell to OEM manufacturers such as Volvo, Scania and Mercedes as well as commercial fleets, multiple certifications are required to prove Quality, Safety and Efficacy of the Technology. We offer a 10 Year Full Replacement Global Warranty and we have achieved ZERO defect and failure rate since 2011.

My charger has a maintenance program built in, does this not achieve the same thing?
A direct comparison can not be made because our technology is an on-board 24/7 conditioning technology whereas a charger limits you to being stationary, but more importantly these chargers do not employ Pulse Technology instead they pulse the DC charge on and off very quickly making them very efficient chargers but in no way can they achieve what VEES and HD648 patented dual pulse technology can and they add no direct benefit to the on on-board electrical systems. 

How much longer will batteries last with VEES and HD648 Technology?
Battery life varies depending on many different factors. By using VEES or HD648 Green Energy your batteries will last up to three times longer. There is enough reactive material in a battery to perform the energy transfer process for upwards of 10 years, but Degradation prevents that from happening. By eliminating Degradation, your batteries and electrical system achieve maximum voltage and maximum service life. Our patented technology has been evaluated by CSIRO, Unitech Energy, Volvo Sweden, Scania Sweden and Mercedes Norway as well as many commercial fleet operators.


Will VEES and HD648 Technology help electrical components?
By maintaining batteries in peak condition, alternators do not have to work as hard. Healthy batteries start engines easier, so your starter motor will also last longer. An added benefit is maximum fuel economy and reduced Greenhouse emissions due to your vehicle's electrical system running at maximum voltage.

Will VEES and HD648 work on Gel-Cell or AGM batteries?
VEES . and HD648 Green Energy work with all batteries except lithium and nicad.

Will VEES and HD648 technology work with different voltage systems?
Yes, VEES and HD648 Green Energy are multi-voltage, auto-sensing and auto-setting devices. Either model can be used with all DC systems from 6 volt to 48 volt. VEES and HD648 can also be installed in series, using multiple units to condition large battery banks with voltages above 48 volts. For example, a 144 volt system can be fitted with three units working at 48 volts. Please contact us for specific advice for your installation.

Can VEES and HD648 be connected while charging a battery?
Yes VEES and HD648 work in both the charge and discharge cycle and are completely independent of the charge system therefore unaffected regardless of the charge coming in or going out of the battery.

Will VEES or HD648 drain my battery if it is not being charged?
VEES and HD648 use 10 milliamp per hour and a total of 240 milliamp per day, plus they have built in automatic  low voltage disconnect functionality which cut off at 50% depth of discharge, therefore you will always be able to start your engine. Obviously the low voltage disconnect will only take place if a vehicle is left sitting idle for extended periods of 8 weeks or more.

Does sulfation/degradation build-up occur on new batteries?
Battery plate degradation/sulfation begins the minute a battery is cycled and  the rate of degradation will vary depending on battery usage and condition. It will occur in batteries that are used infrequently and batteries that are  used daily. New batteries may already be degraded when they are installed on your vehicle as a result of self discharge which occurs even if the battery is not connected, so new batteries sitting on a store shelf for months can suffer from Degradation. 

Can VEES or HD648 be used on more than one battery at a time?
VEES and HD648 Green Energy are designed to work with a battery, or a bank of batteries, of up to 1500/2000 ampere hours (Ah) per unit. For banks above 1500/2000 Ah, adding further units in series will increase the rating by 1500/2000 Ah per unit. Please contact us for specific installation instructions.

Can VEES and HD648 be moved from battery to battery?
VEES and HD648 Green Energy can be moved from battery to battery (minimum three months), therefore up to 4 applications can be conditioned per annum reducing the unit cost and increasing the investment payback even more. Degradation happens 24-hours a day, from the moment acid is added to the battery. Although you can use our technology part-time, a permanent installation will give maximum result because it eliminates existing Degradation and prevents it from re-occurring 24/7 when permanently installed.

Is VEES or HD648 a charger?
No. VEES and HD648 Green Energy are a maintenance system. They will not recharge a discharged battery. They are battery desulfators which rejuvenate sick batteries by reversing degradation. VEES and HD648 can be used in conjunction with any voltage regulated charging system including AC-DC, DC-DC,  Wind and Solar etc...


Will VEES or HD648 harm vehicle computers or electronics?
 Our technology has been tested by Volvo, Scania, Mercedes, Unitech Energy and CSIRO and was found to be safe on all DC electrical systems used in vehicles, vessels, equipment and crafts including on-board computers and electronics.

How does VEES and HD648 impact the environment?
VEES and HD648 Green Energy help protect the environment from the hazards of discarded lead-acid batteries by reducing the number of batteries produced, recycled or dumped in landfills every year. The damage caused by lead and sulphuric acid leaking from batteries that have been disposed of inappropriately is alarming. Even small amounts of lead can cause severe damage to animals and humans who ingest it. The most effective way of reducing the number of discarded batteries is to keep them in service longer. Equally as important is the reduction of Greenhouse pollutants and carbon achieved when vehicles run at maximum efficiency, which is the result of electrical systems working at full voltage enabled by a healthy battery.

Can I upgrade my old Model to the latest VEES model?
Yes, our Customer Care Policy allows our customers to return an old model and purchase the latest model at 50% discount off the Retail Price.
