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 **a 1-year official warranty** from the manufacturer.

### 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 check that the Varta LA105 battery fits my vehicle?

Three ways: 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 for the LA105; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET).

### 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 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.

### How many years of warranty does the LA105 model cover?

The official manufacturer warranty is 1 year and covers manufacturing defects. It applies to defects such as damaged cells, internal short-circuits or abnormal capacity loss. Damage from misuse is excluded: prolonged overcharging, unsuitable chargers or a faulty alternator. On confirmed defect after technical inspection, we replace the LA105 model at no cost.

### When will I receive the LA105 model?

In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships.

### How do I return the LA105 model if it doesn't fit?

Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period.

### What is the price of this battery?

The current price at baterias.com is 243,20 € (VAT included; 200,99 € excl. VAT), updated every 24 hours. The applicable VAT may vary with the destination country and is confirmed in the cart. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery).

### Where can I buy the Varta LA105 battery?

At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point.

### 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.

### How many kilos does this battery weigh?

It weighs 28,5 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre).

### How many Ah and CCA does this battery have?

Nominal capacity 105 Ah[?cca: and [cold-cranking amps 950 A]] at 12 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer.

### 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 9:00–18:00 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.

### Is this battery a better choice than another equivalent?

This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section.
