How to choose the correct leisure battery:

Step 1Understand the conditions of use of the battery

At Installation

Exide Gas

Battery location

Most batteries need ventilation as well as isolation when installed in the vehicle since during use they will give off a mix of hydrogen and oxygen gasses. By using batteries with internal gas recombination features minimal gas emissions are regulated by the valve (VRLA) so special ventilation or isolation is not required. VRLA batteries can also be installed for locations like inside the passenger room or under the driver seat.

Exide Inclination

Mounting Position

Often a vehicle’s layout will restrict where batteries can be installed. By selecting a battery with our high inclination feature it can be positioned at a steep angle. This offers maximum flexibility when working around space constraints


During Service Life

Exide Maintenance


Traditionally batteries require periodic inspections for water topping up cleaning and recharge. This is sometimes arduous due to access difficulties lack of time or inexperience. By using batteries with “maintenance free” features time dedicated to maintenance will be drastically reduced because there is no need to inspect electrolyte levels or to clean spillages. Self-discharge is also extremely low during resting periods reducing the frequency for recharges.

Exide Charging


The engine alternator usually recharges the battery during driving time. Nevertheless to keep batteries at a full state of charge you can undertake complementary recharges by using chargers plugged into the mains during parking time. By using batteries with “faster recharge” features (together with efficient chargers) you can reduce the time needed to complete a full recharge by up to 50%. Also recharge from the alternator will become more efficient.


For Vehicle Upgrade

Exide Energy

Energy Reserve

Batteries fitted to motorhomes or caravans have the capacity to provide the total amount of energy (Watt x hour) required for a trip. So when new equipment is installed or longer trips are foreseen extra capacity will be needed to supply enough power. However room for extra batteries is usually limited so extension is not feasible. By using batteries with our “High energy density” feature room dedicated to batteries can be optimised as either more energy will be stored in the same volume or the same amount of energy will require less volume providing a space saving of up to 30%.
