Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 29.4 kg and has terminal 1 and a B13 hold-down. ### Format and fitting of the Varta H15 The Varta H15 is made in the 393 × 175 × 190 mm format and weighs 29.4 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 B13 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 Varta H15 and the Dynamic AGM range The **Dynamic AGM** range (gold label) is Varta's flagship for cars: AGM technology, with the electrolyte absorbed in glass fibre, designed for the most advanced Start-Stop systems and for regenerative braking. It withstands thousands of charge and discharge cycles without losing performance and is the only correct choice when the car came with AGM from the factory. Ideal for vehicles with high electrical consumption and very frequent starts. In a modern vehicle the battery powers ever more electronics even with the engine switched off. This series is sized for that draw and for restarting the engine dozens of times a day without losing performance, something a traditional starter battery cannot cope with. *This battery used to belong to Varta's **Dynamic AGM** range; following the brand's commercial renaming (2025), it now forms part of the new **Dynamic AGM** series.* ### 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 a Varta means, in practice, giving the vehicle back the battery its manufacturer had specified. Varta batteries are made under the Clarios group with German technology and quality controls that make them one of the best-selling choices in Europe. As a lead battery, it is 100% recyclable through any collection point. 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. ### Manufacturer's warranty The Varta H15 battery comes with the **official manufacturer warranty**. ### Care and maintenance In a Start-Stop vehicle the battery works much harder, so it pays to drive far enough for it to recharge and to always replace it with the same type (AGM for AGM, EFB for EFB) so as not to throw the electronic management out of calibration. For it to perform at its best, avoid overly short journeys, which stop it recharging after each start. Keeping the terminals clean and the hold-down secure prevents failures caused by vibration in the engine bay. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data.

What does this technology offer? Yes. AGM (Absorbent Glass Mat) technology, 105 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. It is the technology required by cars with advanced Start-Stop and regenerative braking. It withstands more cycles than a conventional battery and copes better with heat. ### Is the H15 model suitable for Start-Stop cars? AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. The Varta H15 is AGM, so yes, it is designed for Start-Stop cars. It needs nothing to work, though on most modern cars registering it via OBD is advisable so the alternator adjusts its charging profile. The general recommendation is EFB for basic Start-Stop and AGM where there is regenerative braking (it handles more cycles), unless the car manufacturer says otherwise. ### How do I replace a Start-Stop car battery with the H15? Start-Stop or BMS specifics: do not remove the IBS sensor on the negative terminal (just loosen the cable nut); after the swap, register the battery via OBD so the alternator charges with the right profile; and never step down in technology: if the car had AGM or EFB, the new one must be the same or better, as a conventional battery lasts only a few months. Allow 15-30 minutes and a 10 mm spanner for a L6 case like this one. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the right) to match the polarity; 6) connect the positive (+) and finally the negative (−). Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. ### How long does the Varta H15 battery last? As a rough estimate, the Varta H15 typically lasts 5 to 8 years in mild-climate car use with Start-Stop; it is a guide figure, not a guaranteed period. 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 car itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte. ### What are the dimensions of the Varta H15 battery? Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. The Varta H15 takes up 393×175×190 mm (length, width and height, terminals included), the European L6 case size, with a B13 hold-down. ### On which side is the positive of the H15 model? Polarity of the Varta H15: positive on the right. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. ### Will the Varta H15 battery fit my car? The H15 typically fits a wide range of European vehicles thanks to its standard DIN case format. 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 car 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)). The car manufacturer's specifications always take priority over our tables. ### Which interchangeable batteries are there for this one? Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the H15, 105 Ah (950 A cranking). Technology matters too: in Start-Stop cars, an EFB cannot be replaced with a conventional battery. The options at the same level are in the "Equivalents" section of this page. ### Varta H15 or Varta LA105: which one to choose? Same range and the same performance as the H15. Compared with the H15 it has the same Ah and cranking power. It costs 54,60 € more. Either one works; decide by price. ### What advantages does the Varta H15 AGM battery offer over an EFB? Hence it is recommended for advanced Start-Stop with regenerative braking, such as BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO or Volvo i-Stop, and it handles tilting, vibration and extreme temperatures better than an EFB. The absorbent glass-fibre mat of an AGM retains the electrolyte, so it cannot leak and withstands considerably more cycles than a conventional battery. The Varta H15 has a capacity of 105 Ah. ### Do I need to register the Varta H15 on the car after installation? Advisable, yes; essential, on most cars, no. Registering it via OBD makes the alternator charge with the optimum profile from the first minute and extends battery life, which matters most on brands with sophisticated BMS such as BMW, Mercedes, Audi, Volvo or Land Rover. A workshop only needs an OBD scanner and a few minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register the H15, it will keep starting fine while the alternator adjusts the profile over a few days. ## Equivalent batteries - [VARTA LA105](https://baterias.com/gb/battery-varta-la105agm-12v-105ah-950a) ## Reviews - **Average rating**: 5 / 5 (2 reviews) Average rating 5/5 from 2 verified-purchase reviews (ks_recovery, unfiltered).
