How do you know which way to put batteries in?
Look for a plus symbol on your battery.
The plus sign, or +, indicates the positive terminal. On AA, AAA, C, and D batteries, the positive end should be slightly raised. The negative end of the battery should be flat, and it may or may not be marked with a minus, or -, symbol.
The batteries have one flat side, which is always the positive side, and a rounded side, which is the negative side. The positive side is indicated with a “+” anyway, so you could work this out by inspecting the battery, but the consistency of the design means that you don’t need to do this.
