1. What is the purpose of battery holder?

The primary function of a battery holder is to keep batteries firmly in position while enabling power to be transmitted from the batteries to the device it is connected to. Battery holders may be engineered to accommodate various battery types and can have a cover to protect or confine the batteries and prevent damage from battery leakage to the circuitry and components.The internal electrical connection of a battery holder is usually established via coiled spring wire or flat tabs that exert pressure against the battery terminals. External connections may be achieved via contacts with pins, surface mount feet, solder lugs, or wires. Battery holders make it simple and safe to change the batteries and retain them securely.

2. What is a AA battery holder?

AA battery holders are utilized to secure AA batteries and provide them with electrical connectivity. They are frequently employed in a variety of electronic gadgets, including toys, flashlights, and other small electronic devices. AA battery holders are available in various sizes and forms, with some incorporating additional functionalities such as on/off switches and leads for ease of connection to other components.

3. What types of battery holders are available?

We offer a wide range of battery holders to fit your project's needs. You'll find common sizes like AA, AAA, and 9V, as well as specialized options for 18650 Li-ion cells and CR2032 coin batteries. We stock both single-cell holders for simple circuits and multiple-cell holders in series or parallel configurations to achieve your desired voltage and capacity.

4. Are 18650 holders compatible with Li-ion batteries?

Yes, absolutely. 18650 battery holders are specifically designed to house 18650-sized Li-ion batteries. These powerful rechargeable cells are a popular choice for robotics and portable electronics. The holder provides a secure mechanical and electrical connection, making it easy to integrate the powerful lithium-ion battery into your design. Always check the holder's specifications for your project's current demands.

5. How do I choose between single or multiple cell holders?

Your choice depends entirely on your project's power requirements. A single cell holder is perfect for low-voltage applications or when space is tight. If you need higher voltage, select a multiple cell holder that connects batteries in series. To increase capacity and runtime while keeping the voltage the same, choose a holder that connects cells in parallel. Analyze your circuit's needs first.

6. Do these cases have built-in switches or wires?

Many of our battery holders are designed for convenience, coming with pre-soldered wire leads for quick and easy circuit integration. Some enclosed battery cases also feature a built-in on/off switch, which can simplify your project by eliminating the need for an external one. Always check the specific product description and images to see if a model includes these helpful features.

7. What’s the voltage output per cell configuration?

The total voltage output is determined by the battery type and the holder's wiring. When cells are in series, their voltages add together; for example, three 1.5V AA batteries in series will output 4.5V. If cells are in parallel, the voltage remains that of a single cell (e.g., 3.7V for a Li-ion), but the overall capacity (mAh) increases.

Safety Tips for Li-ion & Alkaline Batteries

Li-ion Battery Safety

Always use a protection circuit or BMS when using Li-ion cells.

Do not short-circuit or overcharge; use proper chargers rated for 18650/21700 cells.

Avoid using damaged or puffed cells; replace immediately.

Do not mix cells of different brands, capacities, or ages.

Keep away from heat sources and avoid storing inside closed hot environments.

Alkaline Battery Safety

Remove batteries when not in use to prevent leakage.

Do not mix old and new batteries together.

Insert cells with correct polarity (+ / –) as marked on the holder.

Store in a cool, dry place to extend shelf life.
