Description
A 4-slot AAA battery holder is a device designed to hold and connect AAA batteries in series, typically arranged in a compact housing. Here are the key features and details:
1. **Battery Type:** AAA (Triple-A) batteries are small cylindrical batteries commonly used in various electronic devices.
2. **Number of Slots:** The holder accommodates four AAA batteries, allowing them to be connected in series to provide a higher total voltage.
3. **Configuration:** The batteries are usually arranged in series, which means the positive terminal of one battery is connected to the negative terminal of the next, creating a cumulative voltage.
4. **Construction:** The holder is often made of plastic and has slots or compartments for each individual AAA battery. It may include a cover or lid to secure the batteries in place.
5. **Terminal Connectors:** The holder has metal contacts or spring-loaded terminals that make electrical contact with the positive and negative terminals of the AAA batteries.
6. **Wire Leads:** Some holders come with wire leads attached to the terminals, making it easier to connect the battery holder to an electronic circuit.
7. **Polarity Markings:** The holder typically has markings indicating the polarity (positive and negative) for proper battery insertion.
8. **Applications:** Battery holders are commonly used in various electronic projects, devices, and prototypes where a convenient and removable power source is needed.
9. **Voltage Output:** In a 4-slot AAA battery holder, the total voltage output is the sum of the individual battery voltages. For alkaline AAA batteries, each battery typically provides around 1.5 volts, resulting in a total of approximately 6 volts.
10. **Latch or Lock Mechanism:** Some holders have a latch or lock mechanism to securely close and hold the batteries in place.
11. **Compact Size:** AAA battery holders are designed to be compact and portable, making them suitable for applications where space is limited.
These holders are widely used in a variety of electronic projects, toys, remote controls, and other devices that require a convenient and replaceable power source. When using a battery holder, always ensure that the batteries are inserted with the correct polarity to avoid damage to the connected circuit or device.
