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.
Outdoor solar lights and solar garden lights use rechargeable batteries to keep the lights lit at night. Each solar light has a solar panel that charges the rechargeable batteries by the sun during the day.
