RMRS
The water-activated battery system "magnesium chloride copper" (MXM) is durable, resistant to mechanical loads and climatic factors. It provides electricity to the lighting devices that are included in the kit of life jackets, suits, rafts and other means of saving people who have had an accident in the sea or fresh water. When it enters the water, it is automatically filled with it and thus activated. Characterized by ease of operation and performance in a wide range of temperatures and pressures.
