## Description

## Battery Varta LL150 Professional Li-Ion Deep Cycle 150Ah 12V

The Varta LL150 150Ah 12V is a LiFePO4 deep-cycle lithium battery, designed as a service bank for boats, motorhomes and solar installations.
It is not a starting battery: its job is to power onboard loads (fridge, fishfinder, GPS, lights, inverter) through deep daily discharges, maintenance free and with thousands of cycles of service life.

## Why choose a **LL150** lithium battery?

LiFePO4 lithium batteries in the Professional Deep Cycle range are built for installations with daily, sustained consumption: motorhomes, marine, solar power and auxiliary equipment. Compared with an equivalent lead-acid battery they weigh around 60 % less and take up less space.
Their LiFePO4 chemistry withstands **thousands of charge and discharge cycles** without degrading, and lets you use virtually all of the rated capacity, whereas lead-acid should not be taken below 50 % if you want it to last.
It includes a **BMS** (battery management system) protecting against overcharge, deep discharge, short circuit and out-of-range temperatures, so the installation stays safe unattended.
- **Light**: around 60 % lighter than a lead-acid battery of the same capacity

- **Cycles**: thousands of service cycles against the hundreds of a conventional battery

- **Usable capacity**: uses nearly all of its rated capacity without shortening its life

- **Maintenance-free**: sealed, no gassing or topping up, can be mounted in any position

- **Fast charging**: accepts high charge currents and is not harmed by partial charge

- **Built-in BMS**: electronic protection against overcharge, deep discharge and short circuit

## Frequently asked questions

### How do I check that the Varta LL150 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 LL150; 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 is the Varta LL150 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 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.

### What is the warranty period of this battery?

This battery includes 2 years of official manufacturer warranty against 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. If the battery fails, we replace it at no cost after a technical inspection.

### How long does Varta LL150 delivery take?

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 LL150 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.

### Where can I buy the Varta LL150 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.

### How many years does this battery last?

Expected lifespan of the Varta LL150 is 4 to 7 years in regular use (depends on technology and climate). 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 size is this battery?

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.

### How much does the Varta LL150 battery weigh?

It weighs 20 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).

### Will the Varta LL150 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 9:00–18:00 CET). The LL150 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the LL150 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 the LL150 model better than its equivalents from other brands?

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.

### What reviews does the LL150 model have?

The product rating, when available, is shown on the product page next to the stars. You can also check our public Trustpilot profile at shop level (4.4/5 from 10,814+ verified reviews). Most-praised points: reliable cold start, lifespan above 5 years and fast delivery; most common complaints mention BMS-equipped boats that need OBD registration after fitting.
