Cold weather, infrequent use and repeated short journeys can all leave a vehicle battery without enough charge to start the engine. A suitable battery charger or maintainer can help preserve batteries in seasonal vehicles, trailers, vans and machinery, while a charged jump starter or power pack provides useful backup when mains power is unavailable.
A practical vehicle breakdown kit should reflect where and how the vehicle is used. Alongside correctly rated jump leads and recovery equipment, useful roadside essentials can include warning equipment, a torch, protective gloves and basic tools—kept together, accessible and checked periodically rather than buried beneath the load when needed.
