Choosing The Correct Leisure Battery

4 Apr 2020

Yuasa Active Leisure and Marine batteries are built to handle the demands of repeated cycle and deep discharge, and to last longer. By following a few simple tips and looking after your battery correctly you can get the maximum possible service life.

Always take care and follow the correct health and safety guidelines to protect yourself from serious injuries from fire, explosions or leaking acid.

Yuasa have launched the new YBX Active range for Leisure, Marine, Specialist and Garden applications.

What is a Leisure and Marine Battery?

Leisure and marine batteries are known as deep cycle types. This means they provide long-term energy delivery and are capable of a much greater number of deeper discharge cycles than automotive, or car, batteries.

Yuasa’s Active range features three types of battery technology. Conventional Flooded, Enhanced Flooded (EFB) and Absorbed Glass Matt (AGM).

AGM batteries can also be used without venting, unlike conventional and EFB types which should be fitted in a vented locker or with a vent pipe.

All Yuasa Active batteries are maintenance free so there is no need to check liquid levels or top up.

Seasonal Use

Some caravan and motorhome owners are under the misconception that a leisure battery is a fit and forget product, however, this is not the case. If a battery is not maintained when not in use for long time periods its condition will deteriorate and it may need replacing. In these cases, the battery has not failed because of any manufacturing or material defect but due to lack of care and maintenance when not in use for prolonged time periods.

Choosing the right battery

It might sound obvious, but always choose a battery of the correct specification and technology to meet your needs. Using the wrong battery will result in a short service life.

There are three factors to consider when choosing your battery:

Battery Size

A leisure battery’s size will be limited by the amount of room physically available in your caravan or motorhome’s locker and tray. Be sure to select a battery that will fit the space you have available.

1080 Watt Hours

Watt Hours

This is the amount of power the battery can supply when fully charged. You can calculate your requirements by working out the consumption of the accessories the battery will power, and how long you usually use them for.

An example of how this is calculated could be:

– TV rated at 80 Watts on for 5 hours takes 80 x 5 = 400-Watt hours

– 5 light bulbs rated at 20 Watts for 4 hours takes 4 x 20 x 4 = 320-Watt hours

– Water pump rated at 50 Watts for 1 hour takes 1 x 50 =50-Watt hours

Total = 770-Watt hours

It is then advisable to factor in a 20% safety margin as the figures used for the capacity calculation can go up or down.

Total battery requirement is therefore 924-Watt hours.

The required battery capacity will also be dramatically affected if using motor mover equipment which consume large amounts of power over a very short time.

420 Cycles

Cyclic Life

The number of times the battery can be discharged to 50% then fully recharged. The higher the cyclic life, the more work the battery can do during its life in service.

90 Ah


The amount of power the battery has to run your equipment. The higher the battery’s Ah rating, the longer it will operate your gear.

NCC Verification

The NCC’s Verified Leisure Battery Scheme ensures it is easy to identify which batteries on the market are quoting accurate, verified specifications.

NCC verification provides confidence that the battery is fit for purpose and will perform as advertised.

All verified batteries are put through comprehensive testing by suitably certified and audited test houses. Once verified, batteries are graded depending on their capacity, cyclic life and intended purpose.


Upgrade for maximum life

The Yuasa Active Leisure and Marine range is tiered, with different levels of performance and cyclic life available. EFB batteries offer a significant increase in cycles over conventional types, and AGM offers the maximum possible cyclic performance.
