Here's a Description of its main Features:

Capacity: This battery holder is designed to house four AA batteries, typically providing a total voltage of 6 volts (assuming standard 1.5V AA batteries). The holder's capacity is suitable for a wide range of low to moderate-power devices.

Construction: The case is usually made from durable materials like ABS plastic, ensuring resilience and protection for the batteries. It often comes with a securely fitting lid, which can be snap-on or screw-on, to keep the batteries in place and shield them from external elements.

Compact and Lightweight: Due to its small size and lightweight design, the 4 x AA battery holder is ideal for applications where space and weight considerations are important. It is often used in portable electronic devices, toys, and DIY projects.

Wiring Configuration: The case features a wiring configuration that connects the batteries in series. This arrangement means that the positive terminal of one battery is connected to the negative terminal of the next, resulting in a cumulative voltage of 6 volts.

Terminal Contacts: Like larger battery holders, the 4 x AA holder has terminal contacts marked as positive (+) and negative (-). These contacts allow for easy integration with external circuits or devices, making it simple to power various electronic components.
