Lorries, buses, tractors and construction machines combine large diesel engines, long hours of operation and constant vibration. Their batteries need high cranking current, generous capacity and robust internal construction. Most heavy vehicles run at 24 V using two identical 12 V batteries connected in series, so both are usually replaced together. ## Sizing a heavy-duty battery Commercial vehicle batteries typically range from around 100 Ah to over 200 Ah. Check the **capacity**, the **CCA/EN** and the **case dimensions**, as truck trays are designed for specific formats. Terminal layout matters too: many heavy vehicles use a layout where the positive is on a specific side, and reversing it complicates the wiring between the two batteries. ## Duty types - **Long-haul trucks**: besides starting, the batteries feed the cab overnight (heating, fridge, lights). Higher cycling resistance, as in EFB or heavy-duty designs, extends life. - **Agricultural and construction machinery**: frequent vibration and seasonal use. Look for vibration-resistant construction and keep batteries charged during idle months. - **Delivery vans and buses**: many short stops and electrical loads; capacity and recovery from partial discharge matter more than peak CCA. ## Replacing a 24 V pair Fitting one new battery next to an old one unbalances the pair: the weaker unit limits the set and drags the new one down. Replace both with the same model and capacity, and clean the connecting cables and terminals at the same time. Check the alternator output once the new batteries are installed. Tighten terminals to the correct torque: vibration loosens poor connections, which then overheat and cause voltage drops that look like a battery fault. Brands like [TUDOR](https://bateriasonline.es/en/tudor-batteries) and [FULMEN](https://bateriasonline.es/en/fulmen-batteries) offer heavy-duty ranges for commercial use.

Overnight discharges followed by incomplete recharging cause gradual sulphation. A battery may still crank in summer and fail on the first cold morning. ### Can I use a car battery in a small tractor? For light tractors and small machines with compatible size and CCA, yes, as long as it is firmly secured. For larger machinery, a heavy-duty battery handles vibration and long cranking far better. ## Choose by brand The same truck, commercial and agricultural vehicle batteries, filtered by manufacturer.
