## Quick description

**Varta 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.

## Why this marine battery?

- **Marine design** built for boat swell and vibration
- **Dual function** starts the engine and powers onboard services
- **Sealed and safe** maintenance-free even when the boat rolls

## Description

## Varta LA105 Professional Dual Purpose AGM 105Ah 950A 12V Battery

12*V* Voltage
105*Ah* Capacity
950*A* Cold cranking
29,4*kg* Weight

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.
- Ideal for motorhomes, marine use and domestic power on board.
- Dual cycle: it both cranks the engine and powers auxiliary equipment.
- More endurance on board than a conventional starter battery.
- Tolerates deep discharges and repeated recharging without degrading.

### Vehicles compatible with the Varta LA105 battery

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.

### Size and fitting of the Varta LA105

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 Varta LA105 and the Professional Dual Purpose AGM range

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.

### Why choose a Varta 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.

### Manufacturer's warranty

The Varta LA105 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.

## Frequently asked questions

### Is the Varta LA105 an AGM battery and what are the benefits of AGM?

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.

### How do I fit the LA105 model in my boat?

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 our blog. 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 — with positive on the right 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.

### What is the service life of the LA105 model?

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.

### What are the measurements of the LA105 model?

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.

### On which side is the positive of the LA105 model?

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.

### Is the LA105 valid for my vehicle?

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.

### What are the equivalents of the LA105 model?

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.
