2. Cutoff voltage - Wikipedia

   en.wikipedia.org/wiki/Cutoff_voltage

   In batteries, the cut-off (final) voltage is the prescribed lower-limit voltage at which battery discharge is considered complete. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved. The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery ...

3. Electric battery - Wikipedia

   en.wikipedia.org/wiki/Electric_battery

   Deep-cycle lead–acid systems often use a low-charge warning light or a low-charge power cut-off switch to prevent the type of damage that will shorten the battery's life. [68] Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, which slows the side reactions.

4. Thermal cutoff - Wikipedia

   en.wikipedia.org/wiki/Thermal_cutoff

   Thermal cutoff. An assortment of thermal fuses. A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).

5. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [ 1 ][ 2 ] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the ...

6. Kill switch - Wikipedia

   en.wikipedia.org/wiki/Kill_switch

   Kill switch. A kill switch, also known more formally as an emergency brake, emergency stop (E-stop), emergency off (EMO), or emergency power off (EPO), is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner. Unlike a normal shut-down switch or shut-down procedure, which shuts down all ...

7. Separator (electricity) - Wikipedia

   en.wikipedia.org/wiki/Separator_(electricity)

   Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
