Figure 1 Predatory and HI (host-or prey-independent) life cycles of Bdellovibrio bacteriovorus. The small, motile, monoflagellate, attack-phase bdellovibrios do not divide, except by replication within the periplasm of a gram-negative prey bacterium.
F. Remove the old battery(ies) and replace with the new battery(ies). If your solar spot light has more than 1 or 2 LED lights it will more than likely have more then 1 or 2 batteries in it. Inside the battery holder it will show you how to place the battery.
Solar lights are made up of solar cells, a small battery, and a light bulb. The solar cells transfer and store the sun's energy into the small battery. The battery then powers the light bulb. The result is an energy efficient bulb with bright light. No electricity required.
