Battery types such as the 9-volt have snap-on contacts. Battery holders for zinc-air batteries must not be completely air-tight since approximately 1 litre of air is required per ampere-hour of discharge per cell. The battery holder may include a valve integrated with the device power switch to allow air to be admitted when the device is ...
mount electrical equipment from AEG and the BBC indifferently. An extremely light chassis structure and a particularly careful design of the electrical part were used to contain the mass, achieving the goal with a deviation of less than 3% (86000 kg for locomotives with AEG electrical part and 85 400 kg for those with BBC equipment).
