Protect your expensive batteries from damage from over-discharge with this mini electronic shut-off switch. It consumes almost no power and can be made to accommodate a wide range of battery voltages. In this new "Micro Battery Protector" we have removed the low battery warning circuit and the relatively inexpensive N-Channel MOSFET used in the Battery Protector and replaced it with a small physical module. than. helps to consume less battery power.
It is slightly more expensive but has a lower voltage switch, allowing use with 6V and 12V lead acid batteries as well as 4 to 10 cell NiCd and NiMH batteries. Most battery-powered devices do not have a mechanism to disconnect the battery when the battery runs out. Even if the voltage drops too low for normal operation, battery discharge usually continues until all available energy is exhausted.
This is especially true for equipment designed to run on alkaline or carbon batteries but equipped with rechargeable batteries. Another example is emergency lighting and safety equipment designed to be recharged from the mains. During extended shutdowns, the battery may completely drain and not recover when power is restored.
