## Description

The Dual Purpose AGM range performs two functions on board: starts the engine and powers the boat or caravan services.

## Technology

AGM technology allows it to deliver the starting current peak and, at the same time, withstand repeated deep discharges without losing capacity. Being sealed, it does not emit gases under normal conditions and can be installed in enclosed spaces or in inclined positions, which is common in boating. It resists vibration and rocking without the electrolyte stratifying.

## Applications

- Boats with a single battery for starting and services
- Caravans and campers with mixed installations
- Recreational vehicles with fridge, lighting and inverter
- Installations where there is no space for two batteries

## The range in figures

References 8
Capacity 50 – 210 Ah
Cold cranking 540 – 1200 A (EN)
Voltage 12 V
Technology AGM

## How to choose

It is the solution when you cannot or do not want to separate starting and service. If daily consumption is high and prolonged, it is more cost-effective to separate the batteries: one for starting and another for deep cycle performs better than a forced mixed one.

## Naming and equivalences

Professional Dual Purpose AGM keeps its name. It is the AGM version of the mixed range: starts the engine and powers the onboard services with a single battery.

## Frequently asked questions

### What is a dual purpose battery?

A battery that combines two functions: delivers the starting current peak and supports repeated deep discharges to power onboard consumption.

### Is a dual purpose battery better than two separate batteries?

Separating the starting bank from the service bank always performs better. The dual purpose is the solution when there is no space or budget for two banks.

### Can it be mounted in an enclosed space?

Yes. As it is sealed, it does not emit gases under normal conditions and allows inclined positions, common in boating.

### What is the difference with the EFB version?

AGM tolerates deeper and more repeated discharges and better resists vibration. EFB has a more contained price and fits when onboard consumption is moderate.

## VARTA Professional Dual Purpose AGM: sealed dual purpose

The **Dual Purpose AGM** combines starting and house duty just like the conventional Dual Purpose, but in AGM technology: electrolyte absorbed in glass-mat, no leaks or maintenance required, with better vibration resistance and more discharge cycles allowed. Being sealed, it can be installed at **any angle**, useful in tight motorhome lockers or boat compartments.

### VARTA Professional Dual Purpose AGM models

- **LA60** (60 Ah / 680 A): small caravan.
- **LA80** (80 Ah / 800 A): mid motorhome or motorboat.
- **LA95** (95 Ah / 850 A): large motorhome.
- **LAD230** (230 Ah / 1150 A): large marine use or premium motorhome.

### How to choose your VARTA Professional Dual Purpose AGM

Compare capacity (Ah), cranking current (CCA) and tray dimensions in our [battery comparison tool](/gb/comparator) before deciding between LA60, LA80, LA95 or LAD230, based on the size of your motorhome, caravan or boat.

## Frequently asked questions about VARTA Professional Dual Purpose AGM

### **Can it be mounted at any angle?**

Yes, being a sealed AGM (VRLA) battery it doesn't spill electrolyte, so it allows installation positions a conventional vented battery doesn't.

### **What's the difference versus the conventional Dual Purpose SLI?**

The AGM handles more discharge cycles and vibration better; the conventional SLI is more affordable for light house use.

### **And versus the Deep Cycle AGM?**

The Dual Purpose AGM still combines starting and house duty; the Deep Cycle AGM is built purely for house use, with more deep-discharge cycles if you don't need to crank an engine.

### **Does it need maintenance?**

No. It's a sealed AGM that never needs topping up with distilled water throughout its life.
