Commercial Vehicles

Frequent short trips, irregular driving profiles with stop-and-go traffic, daily cold starts, and additional electrical consumers like seat heaters and air conditioners reduce your battery’s energy over time.

Some journeys require additional battery power. In many places, environmental regulations ban idling, preventing alternator-based battery charging.

HGV batteries use a 24V system (2x12V batteries in series). They discharge more frequently than car batteries. Special care is needed to charge them regularly. If neglected, the battery voltage can drop below the required threshold for long term serviceability. Charging and maintaining them requires professional charging equipment designed for the task.

Our range of 12V & 24V charging solutions have been specifically designed to maintain commercial vehicles with the ability to charge both batteries individually and together. This increases longevity and health.

Bus Operators

Buses have a hard life. Frequent short trips, irregular driving profiles with stop-and-go traffic, daily cold starts, and additional electrical consumers like ticket machines and onboard cameras reduce your battery’s energy over time.

Journeys require additional battery power. In many places, environmental regulations ban idling, preventing alternator-based battery charging so the battery has to run electrical systems and also operate the doors at every stop.

Bus batteries use a 24V system (2x12V batteries in series). They discharge more frequently than car batteries. Special care is needed to charge them regularly. If neglected, the battery voltage can drop below the required threshold for long term serviceability. Charging and maintaining them requires professional charging equipment designed for the task.
Bus workshops that have introduced our proactive approach to battery maintenance have seen a dramatic reduction of vehicle breakdowns resulting in higher customer satisfaction rates and lower operating costs.

Our range of professional  battery chargers have been designed specifically to service and support 24V systems. To find your perfect charger, contact us for advice

Independent Workshops

It is good practice to connect the vehicle battery to a charger during service. Not only will it charge and condition the battery but it will help compensate for battery drains encountered during service work from having ignition on or even opening and closing doors. Increase customer satisfaction and revenue by providing a battery maintenance service to your customers.

Designed to support a diverse range of passenger vehicles and vans, independent workshops can use one of our charging solutions for a variety of uses. This includes, general battery charging, battery replacement support and diagnostics/ECU Updating work.

Automotive Main Dealers

After purchasing a new or used vehicle, customers often return to the dealer for aftersales support, MOT’s and servicing. As vehicle manufacturers add more power-hungry features to new vehicles, the need for battery maintenance and support has never been so important.

Designed to support a diverse range of passenger vehicles and vans, main dealer workshops can use our charging solutions for a variety of uses. This includes, general battery charging, battery replacement support and diagnostics/ECU updating work.

While some manufacturers mandate a specific make and model battery charger for use in their service centres it is usual that this is not the only model that is required. We can give expert advice on the best charging equipment for your specific needs allowing you to invest in reliable and supported equipment

Emergency Services

Specialist and emergency vehicles require internal systems to run with the engine off, placing high demand on batteries.

It is crucial to ensure that emergency vehicles remain operational at all times. Reports of ambulances being unavailable for duty due to insufficiently charged battery sets is a real concern.

With weight being a critical factor there is usually little scope to increase capacity so proper management is essential to ensure serviceability of the existing  battery pack.
Proactive battery maintenance can ensure vehicles are reliable and stay on the road without an issue. We have real world experience of working with emergency services to audit, recommend and implement battery maintenance programmes that take account of identified needs and respect budgetary constraints.

Our range of battery chargers can support a wide range of emergency vehicles across fire, police and ambulance and include 12V and 24V systems. Get in touch with a member of the team to discuss your options.

Electric Vehicles

With over 1.4 million electric vehicles now on the roads in the UK, service centres are looking for dedicated EV service tools to support customers who have made the switch to electric.

Previously workshops have struggled to service EV’s other than general inspections. In collaboration with Midtronics, we can now offer all service centres access to both module level balancing and 12V EV Auxiliary battery testing and charging.

Get your workshop ready for EV servicing, contact a member of the team for more information.

Showroom

Showroom charging is crucial for vehicle retailers. The growing number of electrical systems in modern vehicles creates challenges when demonstrating them in the showroom and during handover.

Reliance on the starter battery to demonstrate vehicle functions when the engine is off is now commonplace. However, discharged batteries often prevent demonstrations from starting in the first place or possibly worse, lacking the power to complete a demonstration already commenced.

Additionally, the 12V battery may suffer significant damage and require replacement due to deep discharge. We offer 12V chargers from leading brands with outputs up to 50A, specifically designed for use in showrooms. They are simple to operate, provide reliable support for the battery with a clean and safe power supply, and are silent and discreet in operation. These features ensure consistent performance from vehicle demonstration to delivery, maintaining the battery in optimal condition.

Contact us to see how we can help you ensure faultless demonstrations and avoid unnecessary battery replacements.
