Batteries are increasingly common for powering vehicles and in the equipment of individual soldiers. FOI tests batteries to optimise their output, evaluate their life expectancy and reduce the risk of fire and gas formation.

Different types of batteries.

This knowledge is used primarily by FMV, the Swedish Defence Materiel Administration, and the Armed Forces, where submarines, surface vessels and increasing numbers of hybrid vehicles are relied on for stealthy approach to an enemy. The longer these ships and vehicles can run on batteries, the greater the advantage. When Swedish soldiers can use range-finding and night-time equipment for a longer period than their enemy, then they too have the advantage. By knowing how long a battery can withstand external abuse and what happens when it breaks, the risk that people will be injured or killed in fires or through smoke inhalation is reduced.
