Varta I16 12V 120Ah 760A is a professional battery for heavy commercial vehicles. Withstands constant chassis vibration, supports long cold-engine cranks and keeps auxiliary services running (tachograph, heater, refrigeration, GPS) during driver's mandatory rest stops.

The Varta I16 lorry battery is the 12 V, 120 Ah model delivering 760 A of cold cranking power (EN), from Varta's ProMotive SLI (formerly ProMotive HD) range, designed for lorries, buses, large vans and machinery. Measuring 510 × 175 × 235 mm with the positive terminal on the right, it is the direct replacement for lorries that leave the factory with a 120 Ah battery in this format.
The Varta I16 is compatible with more than 159 vehicles: it is fitted as standard or as a replacement by makes such as Lamborghini, Same, Fiatallis, Komatsu, Cimas and Landini. For anyone who needs to change the battery in their Lamborghini or Same, this Varta I16 reproduces the original specifications. Added to that list are models from Hurlimann, Fiat, Volvo, Benati, Carraro, Huerlimann, Atlas and Laverda.
The Varta I16 is made in the 510 × 175 × 235 mm format and weighs 35.12 kg. The positive terminal on the right determines which side the cables end up on: this is the detail behind more wrong purchases than any other, so it is worth checking before you order. It takes a B03 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
The ProMotive SLI range is Varta's starter series for commercial vehicles — lorries, buses and machinery — and in the new portfolio it unifies the former ProMotive HD (Heavy Duty) and SHD (Super Heavy Duty). It offers high cranking current for large-capacity diesel engines and a reinforced construction.
Its reinforced grids and separators stand up to the vibration and cycling of long-distance haulage and of the most severe use, aiming for maximum service life and starting reliability in fleets that work long hours.
Compared with a car battery, this range is calibrated for severe, continuous use: greater mechanical strength and more tolerance of cycling and of the knocks of the road. It is the correct replacement for a lorry, bus or machine working long shifts. This battery used to belong to Varta's ProMotive HD or ProMotive SHD range; following the brand's commercial renaming (2025), it now forms part of the new ProMotive SLI series.
Varta is an original equipment (OEM) supplier to a good share of Europe's car manufacturers: many cars leave the factory with a Varta fitted. Buying a replacement means, in most cases, refitting the original battery with the same quality and the brand's official warranty.
Varta combines more than a century of experience with Clarios's industrial production: it is the battery many manufacturers choose as standard and one of the most recommended by workshops. Like any lead-acid battery, it is 100% recyclable.
Varta's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life.
The Varta I16 battery comes with a 1-year official warranty from the manufacturer. An important warning for commercial vehicles: most lorries run two batteries connected in series (a 24 V installation). If you replace only one, the new battery ends up working alongside the old one — which has already lost capacity and has higher internal resistance — and that imbalance means one overcharges while the other falls short, shortens the life of the new unit and may be treated by the manufacturer as improper use, voiding the warranty. That is why it is always advisable to change both batteries at the same time.
In professional use, checking the state of charge and the battery hold-down regularly prevents breakdowns on the road. Vibration and the high temperatures of the engine bay are what shortens a battery's life most, so secure mounting is key. Keeping the terminals clean and tight and checking the charging system extends battery life in vehicles that clock up long hours. A well-maintained battery reduces the risk of downtime caused by a battery that will not start the engine.

Guide to replace a truck battery in 30-60 minutes. Truck batteries weigh 25-50 kg — we recommend working in pairs and using a carrying strap.
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Loosen the bottom hold-down clamp. Truck batteries weigh 25-50 kg — lift in pairs with gloves and a carrying strap. Forcing the lift alone risks back injury.
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
Three ways: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team for the I16; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET).
In most trucks it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

Expected lifespan of the Varta I16 is 4 to 6 years in regular truck use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
Dimensions (length × width × height) are 510×175×235 mm — also written as 510x175x235 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
It weighs 35,1 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre).
Nominal capacity 120 Ah[?cca: and [cold-cranking amps 760 A]] at 12 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer.
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET). The I16 fits 159 verified vehicle versions in our database.
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop trucks. See the "Equivalents" section to view recommended options at the same performance level.
This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section.
