## Varta LFD90 Professional Dual Purpose 90Ah 800A 12V Battery

12*V* Voltage
90*Ah* Capacity
800*A* Cold cranking
23,73*kg* Weight

The **Varta LFD90 battery** is the **12 V**, **90 Ah** model delivering **800 A** of cold cranking power (EN) from Varta's **Professional Dual Purpose** range, designed for motorhomes, boats and auxiliary power equipment. Its 353 × 175 × 190 mm dimensions and positive terminal on the right make it the exact replacement for the 90 Ah battery fitted as standard in many vehicles.
- Dual cycle: it both cranks the engine and powers auxiliary equipment.
- Ideal for motorhomes, marine use and domestic power on board.
- Tolerates deep discharges and repeated recharging without degrading.
- More endurance on board than a conventional starter battery.

### Vehicles compatible with the Varta LFD90 battery

According to our database, the Varta LFD90 is fitted to more than 12 vehicles from brands such as Elan Marine, MANtra Yachts, Dufour Yachts, Saffierjachten, Nordborg-Baanordborg and Najadvarvet AB, among others. It is a go-to option when you need an **Elan Marine battery**, a MANtra Yachts one or any other model built around this same format. The compatibility list also includes models from Slottayachts, Etap, Hallberg-Rassy, Huntermarine, Salona Yachthandel and Corby Yachts.

### Size and fitting of the Varta LFD90

In terms of format, the Varta LFD90 measures 353 × 175 × 190 mm (length × width × height) and weighs 23,73 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. 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 LFD90 and the Professional Dual Purpose range

The **Professional Dual Purpose** range consists of dual-purpose batteries: they serve both to crank the engine and to power the on-board services, a balance conceived for leisure and marine use.
They are the answer when you want a single battery that starts reliably and at the same time sustains equipment draw with the engine off, without going as far as the extreme cycling of a deep cycle unit.
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

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 Varta means, in practice, giving the vehicle back the battery its manufacturer intended.
Varta combines more than a century of experience with Clarios's industrial production: it is the battery many manufacturers choose as standard and one of the most recommended by workshops. Like any lead-acid battery, it is 100% recyclable.
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 LFD90 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

### How is the Varta LFD90 battery installed in the vehicle?

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.

### How long does the Varta LFD90 battery last?

Expected lifespan of the Varta LFD90 is 4 to 6 years in regular boat use without 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 LFD90 model?

Dimensions (length × width × height) are 353×175×190 mm — also written as 353x175x190 mm and correspond to the European L5 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.

### Which side is the positive terminal on this battery?

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.

### Will the Varta LFD90 battery fit my boat?

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 LFD90 fits 26 verified vehicle versions in our database.

### Which batteries are equivalent to the Varta LFD90?

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.
