Its 353 × 175 × 190 mm dimensions and positive terminal on the right make it the exact replacement for the 95 Ah battery fitted as standard in many cars. - Built for the intensive cycling of the Start-Stop system. - Keeps the vehicle's electronic management correctly calibrated. - Reinforced resistance to the partial charges and discharges of daily use. - More guaranteed starts than a conventional battery. ### Applications of the Varta G14 battery The Varta G14 covers the needs of cars with a Start-Stop system and high electrical demand with 95 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 weighs 26.4 kg and has terminal 1 and a B13 hold-down. ### Format and fitting of the Varta G14 In format, the Varta G14 measures 353 × 175 × 190 mm (length × width × height) and weighs 26.4 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. 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 G14 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. 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 makes cannot always promise. ### Manufacturer's warranty The Varta G14 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. The Varta G14 is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. It tolerates heat better and handles more cycles than a conventional battery, which is why it is the required technology with advanced Start-Stop and regenerative braking. ### Is the Varta G14 battery suitable for Start-Stop? Yes: being AGM, the Varta G14 is designed for Start-Stop cars. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. If the car recovers energy when braking, AGM is recommended for its higher cycle count; for basic Start-Stop, EFB. The manufacturer's specification comes first. Registering it via OBD is advisable on most modern cars (the alternator then applies the optimum profile), but it works from the start. ### How do I replace a Start-Stop car battery with the G14? Allow 15-30 minutes and a 10 mm spanner for a L5 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. If the car has Start-Stop or BMS: a) the technology must match the original (AGM or EFB) or be higher, because a conventional battery would fail within months; b) undo the negative cable at its nut, leaving the IBS sensor in place; c) it is advisable to register the battery via OBD so the alternator applies the proper charging profile. What matters most is the terminal order: removing, negative (−) before positive (+); refitting, positive (+) before negative (−). In between, with the engine off and the key out, release the clamp and fit the new battery the same way round as the original, positive on the right (polarity). Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. ### What is the service life of the G14 model? As a guide, you can expect the Varta G14 to last 5 to 8 years in mild-climate car use with Start-Stop, although the real figure may be higher or lower. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop. ### What are the dimensions of the Varta G14 battery? Length × width × height: 353x175x190 mm (L5 case). Height is measured to the top of the terminals. Hold-down: B13. Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. ### What polarity does the Varta G14 battery have? On the Varta G14, the polarity is positive on the right. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. ### Does this battery fit my car? For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the car handbook disagree, go with what the manufacturer says. ### Which batteries are equivalent to the Varta G14? Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the G14, 95 Ah (850 A cranking). See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop cars an EFB is not swapped for a conventional battery. ### What advantages does the Varta G14 AGM battery offer over an EFB? The Varta G14 has a capacity of 95 Ah. Many more charge/discharge cycles than a conventional battery and no leaks: that is what AGM technology brings, with the electrolyte absorbed in glass fibre. 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). ### Do I need to register the Varta G14 on the car after installation? On most cars it is not strictly necessary: the alternator detects the new battery and adapts the charge by itself. It is advisable, though, to register it via OBD so the optimum profile applies from the first minute and the battery lasts as long as possible, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). To do it yourself: VCDS or Carista on VAG, Bimmercode on BMW, iCarsoft. At a workshop with an OBD scanner it takes minutes. If you do not register the G14, it will keep starting fine while the alternator adjusts the profile over a few days. ## Equivalent batteries - [TUDOR TK950](https://baterias.com/gb/battery-tudor-tk950-95ah-850a) - [EXIDE EK950](https://baterias.com/gb/battery-exide-ek950-12v-95ah-850a) - [VARTA A5](https://baterias.com/gb/battery-varta-a5-agm-12v-95ah-850a) - [EXIDE EK960](https://baterias.com/gb/battery-exide-ek960-12v-96ah-850a) - [TUDOR TK960](https://baterias.com/gb/battery-tudor-tk960-12v-96ah-850a) ## Reviews - **Average rating**: 5 / 5 (3 reviews) Average rating 5/5 from 3 verified-purchase reviews (ks_recovery, unfiltered).
