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.
