Heavy-Duty Commercial Starting Power
Commercial vehicles and working machinery can place significantly greater starting demands on a battery than a typical passenger car. Larger diesel engines require substantial cranking current, while trucks, agricultural machinery and construction equipment can operate for long periods in challenging environments. The Exide EF1421 PowerPRO HDX is designed around these requirements, combining substantial 142Ah capacity with 850A cold-cranking performance and robust heavy-duty construction.
Using the EF1421 in 24V Commercial Vehicles
Although the Exide EF1421 is a 12V battery, many trucks, buses, coaches and other heavy commercial vehicles operate using a 24V electrical system. In these applications, two matching 12V batteries are commonly connected in series to provide the required 24V supply.
When replacing batteries in a paired 24V installation, it is generally advisable to replace both batteries together with two matching batteries. Mixing batteries of different ages, capacities, technologies or states of health can create an imbalance and may reduce starting performance and overall service life.
Type 656 Fitment
The Exide EF1421 uses the Type 656 commercial battery format. Commercial batteries can differ considerably in case height, terminal orientation and mounting arrangement even where the footprint or electrical ratings appear similar. For this reason, the battery should never be selected solely by its Ah or CCA rating.
Always compare the physical dimensions, terminal configuration and mounting arrangement with the battery currently fitted to the vehicle or equipment before ordering.
Important Fitment Information
Before ordering the Exide EF1421, check the specification of the battery or batteries currently fitted. Commercial vehicle applications can vary considerably between models and configurations, so voltage, capacity, CCA, physical dimensions, terminal arrangement and mounting method should all be confirmed.
If the vehicle uses two batteries as part of a 24V starting system, both batteries should ideally be of the same type, capacity, age and specification. Replacing the pair together helps maintain balanced charging and starting performance across the battery bank.
Why Choose the Exide EF1421 PowerPRO HDX?

The most important questions about our high-quality replacement batteries for Truck & Commercial Vehicles
Find the right battery here
Truck & Commercial Vehicles
The easiest way is to use the data of your old battery. Make a note of the capacity, voltage, base strip and circuit. For 100% accuracy you should also measure the size (length, width and height) of the old starter battery. With this data you can easily find the right starter battery.
You don't know what to do? Then send us pictures of all sides of the old battery. We will be happy to help you find the right starter battery for your truck / commercial vehicle.
● Acid: Inside the battery is liquid acid which should be refilled at regular intervals - this is usually the cheapest price variant. We offer sealed lead acid maintenance free options
● AGM (Absorbent Glass Mat Technology): With AGM batteries the electrolyte (acid) is completely bound in a glass fibre fleece, therefore the batteries are leak-proof - medium price variant.
● GEL: The acid in these batteries is thickened to a gel. Like the AGM battery, they are leak-proof and extremely durable - high-quality price variant.
Our powerful AGM starter batteries are used when starting the engine. They are then recharged during the journey. Utility batteries supply your on-board devices (refrigerator, lighting, multimedia, etc.) while you are standing. The supply batteries can also be recharged either via solar cells or during the journey.
Our dual batteries are both starter and utility batteries. The Dual Batteries are ideal for use in small motorhomes. We recommend the use of a starter battery and one or more utility batteries.
Basically, you can adjust the quantity of your utility batteries to the available space. However, please keep in mind the weight limit of your vehicle. You can find more information in your vehicle manual.
Our batteries are packed and dispatched directly after your order by our automated packing line. The delivery time is between 1-3 days. If you need further information about your order, simply contact our service team or use the shipment tracking.
You can return the old battery to us in our shop. Alternatively, please dispose of the used battery at a recycling centre or scrap dealer.
Important: Ensure the respective company provides written confirmation about the disposal of the used battery.
The starter battery is automatically recharged during a longer journey. If you wish to recharge the battery after a longer period of stationary, use a charger.
The starter battery is recharged while driving by the alternator. The starter battery cannot usually be charged enough during frequent short distances. In order for your new starter battery to last longer, you should fully charge it by driving longer journeys or using an optional charger. Alternatively, you can also install an additional solar cell.
The easiest way is to use the data of your old battery. Or have a look at the instruction manual of your truck / commercial vehicle.
Trucks usually have a voltage of 24 volts. If you are unsure, check your old battery or your vehicle instruction manual.
To choose the capacity you should use your old battery as a template. If you are unsure, check your used battery or your vehicle manual.
Many vehicles switch off the engine during short standstills. When choosing the right starter battery, please make sure that your vehicle also has a Start-Stop automatic. For further information, please refer to your vehicle manual.
Check on your old starter battery which baseboard you need. Or take a look at your vehicle manual.
