Why do LED flashlights drain batteries when off?

What happened to the flashlight when you put the battery back on?
When the switch of a flashlight is pushed into the ON position,
it makes contact between two contact strips, which begin a flow of electricity, powered from the battery
. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery.
Which side of battery goes against spring?
Batteries have a positive terminal and a negative terminal.
The negative side
of the battery should be touching the spring when installing it. The purpose of that spring is to ensure that you have the correct polarity when installing the batteries, and it also helps with consistency in knowing which way they go.
Which way do you put batteries in?

.
Does the negative side of a battery go on the spring?
The negative side of the battery goes on the spring
.
Inserting the negative side first allows the battery to slide into the compartment easily. If you carelessly force the battery into the compartment, you could destroy the spring. Springs are durable components that can outlive the device to which they are attached.
Do batteries go negative to negative?
“
Positive first, then negative
. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
