Choosing a leisure or auxiliary battery

These are dual-purpose batteries rather than basic starter batteries. They combine engine-starting capability with better support for repeated auxiliary use, making them suitable for dual-battery systems and vehicles carrying additional electrical equipment.

Battery Best suited to Key specification
Hankook XV27 High-capacity auxiliary and leisure use where stored capacity is the priority. 90Ah / 720CCA
Optima Yellow Top YTS4.2 Compact dual-purpose AGM battery where installation space is limited but strong starting and cycling performance are required. 55Ah / 765CCA
Optima Yellow Top YTS5.5 Larger dual-purpose AGM battery for starting combined with substantial auxiliary electrical loads. 75Ah / 975CCA

Check leisure battery requirements before ordering

A battery can have suitable capacity but still be wrong for the installation. Physical space, terminal arrangement, the electrical load being supplied and the charging system all need to be considered.

Electrical load
Consider the lighting, fridge, inverter, winch and other accessories the auxiliary battery will need to supply.
Battery space
Measure the available length, width and overall height, including clearance above the terminals and around the retaining system.
Terminal layout
Check the terminal position, post type and cable reach so the battery can be connected without stretching or crossing the cables.
Charging system
Confirm that the split-charge system, charger or vehicle charging arrangement is suitable for the battery technology being fitted.

Sealed calcium and AGM dual-purpose batteries

Battery type What it offers
Sealed-calcium dual-purpose battery High stored capacity with engine-starting capability and support for auxiliary or seasonal leisure use.
Dual-purpose AGM battery Strong cranking performance combined with greater resistance to repeated discharge and recharge cycles.
Main and auxiliary installations Battery capacity, physical size, terminal layout and charging arrangement determine whether the battery suits the intended position and electrical load.
