It replaces the original battery in lorries with the 513 × 223 × 223 mm format without any modifications: the same 170 Ah capacity. - Tolerance to the vibration of thousands of kilometres on the road. - High cranking current for large-capacity diesel engines. - Reliability in repeated starts and in powering cab equipment. - Reinforced grids and casing for the severe demands of haulage. ### Applications of the Varta A2 battery The Varta A2 covers the needs of lorries, buses, large vans and machinery with 170 Ah of capacity and a construction built for that use. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a B00 hold-down. ### Format and fitting of the Varta A2 Its outer dimensions are 513 × 223 × 223 mm. It uses a B00 hold-down, the system that anchors it to the vehicle's battery tray. Before replacing it, measure the space your current battery occupies: if it matches on all three dimensions and on terminal position, the swap is direct and needs no adapters. ### The Varta A2 and the ProMotive AGM range The **ProMotive AGM** range is Varta's AGM series for commercial vehicles, with maximum resistance to cycling and vibration. It is designed for lorries that draw heavily on the battery while the engine is switched off. It is the one for cabs with a "hotel load" (air conditioning, fridge and electronics during rest breaks), tail lifts and cranes, where the battery works far beyond simply starting the engine. A commercial vehicle demands a high cranking current and endurance against the vibration of thousands of kilometres. This series uses reinforced grids and rugged construction to cope with repeated starts of large diesel engines and with the draw of auxiliary cab equipment. ### Why choose a Varta battery A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has been supplying the assembly lines of the major car groups for decades. Replacing with Varta means, in practice, giving the vehicle back the battery its manufacturer intended. Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year. Varta is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makers cannot always assure. ### Manufacturer's warranty The Varta A2 battery comes with the **official manufacturer warranty**. One important warning for commercial vehicles: most lorries are fitted with **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; that imbalance means one is overcharged while the other falls short, shortens the life of the new battery, and the manufacturer may regard it as improper use and **void the warranty**. That is why it is always advisable to change **both batteries at the same time**. ### Care and maintenance In professional use, periodically checking the state of charge and the battery's hold-down prevents breakdowns out on the road. Vibration and the high temperatures of the engine bay are the factors that shorten its life the 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 failure to start. ## Frequently asked questions ### Is the A2 model AGM? What does this technology offer? Yes, it is AGM. In an AGM battery such as the A2, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It is the technology required by trucks with advanced Start-Stop and regenerative braking. It withstands more cycles than a conventional battery and copes better with heat. ### Is the A2 model suitable for Start-Stop trucks? Yes, the AGM technology of the A2 is built for Start-Stop. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the truck manufacturer requires. Registering it via OBD is advisable on most modern trucks (the alternator then applies the optimum profile), but it works from the start. ### Why does my lorry have two batteries? Most lorries, buses and tractors run on 24 V with two 12 V batteries connected in series. Always replace both at the same time and with the same model: if one is new and the other old, they become unbalanced and both last less. ### How many years does this battery last? There is no exact figure: for a battery such as the Varta A2 (AGM), a reasonable guide is 5 to 7 years in lorry use, even with high power draw while parked. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance, plus the truck itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte. ### What are the dimensions of the Varta A2 battery? It measures 513×223×223 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Is the A2 valid for my vehicle? Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your truck is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the truck manufacturer's specifications (owner's handbook) take precedence. ### What are the equivalents of the A2 model? A direct equivalent needs what this A2 offers: 513×223×223 mm, the same Ah and CCA and AGM technology. The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop trucks an EFB should not be replaced with a conventional battery. ### Varta A2 or Exide EP1500: which one to choose? Same case and same fitting as the A2, from Exide. Compared with the A2 it has 10 Ah more and 100 A of cold cranking less. It costs €395.90 more. If you want to save or the A2 is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty. ### What advantages does the Varta A2 AGM battery offer over an EFB? Compared with an EFB it resists tilted positions, heavy vibration and extreme temperatures better, and it is the recommended option where there is regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop). AGM means Absorbent Glass Mat: the electrolyte soaks a glass-fibre mat (no spills), and an AGM battery lasts many more cycles than a conventional one. Cold cranking current (EN) of the Varta A2: 1000 A. ### Do I need to register the Varta A2 on the truck after installation? It is not strictly necessary on most trucks, because the alternator detects the change and adapts the charge. The advisable step is to register it via OBD: the charging profile is optimum from the first minute and the battery lasts longer, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). Any garage with an OBD scanner can do it in a few minutes. If you prefer to do it yourself: VCDS / Carista (VAG), Bimmercode (BMW) or iCarsoft. If you do not register the A2, it will keep starting fine while the alternator adjusts the profile over a few days. ## Equivalent batteries - [EXIDE EP1500](https://baterias.com/gb/battery-exide-ep1500-12v-180ah-900a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-11*
