It replaces the original battery in vehicles with the 328 Γ— 172 Γ— 233 mm format without any modifications: the same 115 Ah capacity and the same terminal layout (positive on the right). - Tolerates deep discharges and repeated recharging without degrading. - More endurance on board than a conventional starter battery. - Dual cycle: it both cranks the engine and powers auxiliary equipment. - Ideal for motorhomes, marine use and domestic power on board. ### Applications of the Varta LAD115 battery With 115 Ah, the Varta LAD115 is sized for motorhomes, boats and auxiliary power equipment, as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 32,8 kg and has a type 1 terminal and a B00 hold-down. ### Size and fitting of the Varta LAD115 Its external dimensions are 328 Γ— 172 Γ— 233 mm and it weighs 32,8 kg. The positive terminal on the right determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B00 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will have to change. ### The Varta LAD115 and the Professional Deep Cycle AGM range The **Professional Deep Cycle AGM** range consists of AGM deep-cycle batteries designed to run equipment for hours: fridge, lighting, electric outboard or on-board electronics in boats and motorhomes. They accept deep discharges and repeated recharging that would ruin a starter battery, and being AGM they need no maintenance and carry no risk of spillage. The chemistry is built for draining and recharging the battery many times over β€” the typical pattern in leisure and marine use β€” where an ordinary car battery would sulphate within weeks. It offers endurance for the on-board equipment and the cranking power to turn the engine over when the moment comes. ### Why choose a Varta battery Varta is a byword for reliability: original equipment in numerous European vehicles and one of the most proven brands on the market. Replacing your battery with a Varta restores OEM quality β€” the same performance as the factory-fitted unit β€” with the manufacturer's backing. 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 LAD115 battery comes with the **official manufacturer warranty**. ### Care and maintenance In leisure applications, avoiding discharges below 50% of capacity multiplies the number of cycles the battery will deliver. A suitable charger and, where possible, a solar regulator keep it healthy through the seasons when it sees less use. To extend its life, recharge it as soon as possible after each discharge and never leave it flat over the winter. A trickle charger is the best investment for getting many cycles out of it. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data.

The LAD115 from Varta uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### Is this a starting or a service (leisure) battery? Service: it is designed to power electronics, lights, the fridge or the windlass for hours, withstanding deep discharges. On boats with two circuits the ideal is one starting battery and one service battery. ### In what position can it be installed on the boat? Being AGM, it is sealed and does not spill: it can be mounted tilted (never upside down) and copes well with vibration and wave impacts. Secure it firmly and keep the terminals away from water. ### What are the measurements of the LAD115 model? Dimensions (length Γ— width Γ— height) are 328Γ—172Γ—234 mm β€” also written as 328x172x234 mm β€” following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### What polarity does the Varta LAD115 battery have? Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ### Varta LAD115 or Fullriver FT1100-31ST: which one to choose? Same case and same technology as the LAD115: an alternative by size, not an official equivalent. Compared with the LAD115 it has 5 Ah less and 550 A of cold cranking more. It costs €479.40 more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ### Varta LAD115 or Fullriver FT1100-31: which one to choose? Same case and same technology as the LAD115: an alternative by size, not an official equivalent. Compared with the LAD115 it has 5 Ah less and 550 A of cold cranking more. It costs €486.10 more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-11-02*
