See all 25 reviewsVarta LA105 12V 105Ah 950A is a marine battery with reinforced anti-vibration case for moorings and offshore use. Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea.

The Varta LA105 battery is the 12 V, 105 Ah model delivering 950 A of cold cranking power (EN) from Varta's Professional Dual Purpose AGM range, designed for motorhomes, boats and auxiliary power equipment. Measuring 394 × 175 × 190 mm and with the positive terminal on the right, it is the direct replacement for vehicles that leave the factory with a 105 Ah battery in this format.
This battery is listed as compatible with more than 17 vehicles from manufacturers such as Hanse Yachten, Jeanneau, Delphia Yachts, Etap, Bavaria Yachtbau GmbH and Fora Marine. It is a go-to option when you need a Hanse Yachten battery, a Jeanneau one or any other model built around this same format. Added to that list are models from Harmony Yachts, Dehler, Alubat, Dufour Yachts, Corby Yachts, Huntermarine, Winner Jachten Bv and Hekim.
In terms of format, the Varta LA105 measures 394 × 175 × 190 mm (length × width × height) and weighs 29,4 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 B13 hold-down and a type 1 terminal, 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 Professional Dual Purpose AGM range combines dual-purpose duty (starting + domestic supply) with AGM technology, which brings greater cycling endurance, zero maintenance and safety against spillage.
It is the demanding choice for motorhomes and boats that need to crank the engine and sustain a heavy equipment draw with maximum durability.
Unlike a pure starter battery, this range tolerates deep discharges and repeated recharging without degrading: exactly what a motorhome or a boat that draws power with the engine off needs. It therefore combines cranking and domestic duty in a single dual-cycle battery.
Choosing Varta means going with the reference the car manufacturer itself signed off on in its day. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before leaving you stranded.
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.
More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement.
The Varta LA105 battery comes with the official manufacturer warranty.
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.

Guide to replace a marine battery (cranking or house) in 20-30 minutes. Moisture and vibration in marine environments require reinforced hold-downs and sealed copper terminals.
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.
Usually under the passenger bench, engine room or a dedicated ventilated compartment. Verify the compartment is dry and well ventilated before opening.
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.
Marine batteries are heavy (15-50 kg). If it has rope handles, use them; otherwise have a carry strap ready. Secure the new one with metal hold-downs (not plastic) to resist sea-state vibration.
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.
Apply dielectric grease on terminals to prevent salt-air corrosion. Check the engine charging circuit delivers 13.8-14.4 V at 2,000 rpm.
Yes. The LA105 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.
In most boats 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 boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
Expected lifespan of the Varta LA105 is 5 to 8 years in mild-climate boat use with 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 394×175×190 mm — also written as 394x175x190 mm and correspond to the European L6 case size — 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.
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 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The LA105 fits 28 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 boats. See the "Equivalents" section to view recommended options at the same performance level.
