I can't find any evidence that this would make them last longer. In fact I can't find any evidence of anyone putting flowers in a water & batteries mix.
You can propagate flowers in water by taking a cutting from a healthy plant, placing it in a container of water, and ensuring that the water is changed regularly to prevent bacteria growth.

Using sugar water is the best method for making flowers last longer. The sugar provides nutrients for the flowers to feed off of, helping them stay fresh and vibrant for a longer period of time. Milk can actually promote bacterial growth and hasten wilting.

To successfully propagate flowers in water, cut a healthy stem from the plant and place it in a container of water. Change the water regularly to prevent bacteria growth and place the container in a bright, indirect light. Roots should start to grow in a few weeks, and once they are established, you can transplant the cutting into soil.
You can insulate the container with a towel or place it in a thermos to keep the water warm longer after removing it from sunlight. Additionally, using a lid or covering the container will help retain the heat. Finally, placing the container in a warm spot indoors can also help maintain the water temperature.

How about a vase- contains water and flowers- or a vault- contains money and valuables.
The amount of water in a container will affect how fast it heats up. If there is a small amount of water in a container the water will biol/heat faster. However, if there is a big amount of water it will take longer for the heat to reach all parts of the water resulting in a longer time for the water to boil/heat
To safely travel with a bouquet of flowers, keep them in water to stay fresh, protect them from extreme temperatures, and secure them in a sturdy container to prevent damage.
