SPIDER Automation | 3×AAA Battery Holder with Cover, ON/OFF Switch & Locking Screw | 4.5V Series Battery Case
Product Overview
The SPIDER Automation 3×AAA Battery Holder with Cover and ON/OFF Switch is an enclosed battery holder designed to accommodate three AAA batteries in a series configuration. It combines a compact plastic enclosure, a removable sliding cover and an integrated power switch, providing a convenient battery mounting and power-control solution for electronic projects.
The three battery positions are internally connected in series, allowing the individual cell voltages to combine at the output. With standard 1.5V alkaline AAA batteries, the holder provides a nominal 4.5V output. When using 1.2V NiMH or NiCd rechargeable AAA cells, the nominal combined voltage is 3.6V.
A removable sliding cover secured by a small head screw helps enclose and protect the installed batteries. The built-in ON/OFF switch allows convenient control of power to the connected project, while the pre-attached 15cm wire leads with tinned ends simplify electrical connections.
Technical Features & Construction
- Three AAA Battery Positions: Accommodates three standard AAA-size cells in a single enclosed case.
- Series Battery Configuration: Internally connects the three cells in series to combine their voltage.
- Integrated ON/OFF Switch: Provides convenient manual control of power supplied to the connected circuit.
- Sliding Protective Cover: Removable cover helps enclose the batteries and protect them from everyday external exposure.
- Locking Screw: A small head screw secures the sliding cover in position.
- Pre-Attached Wire Leads: Supplied with approximately 15cm leads for connection to electronic circuits.
- Tinned Wire Ends: Approximately 5mm of the wire ends are tinned to facilitate soldering and electrical connection.
- Plastic Enclosure: Black plastic case provides an organised housing for the three battery cells.
- Compact Form Factor: Approximate external dimensions of 62 × 38 × 16mm.
Battery Configuration & Output Voltage
This holder uses a 3-cell series connection. In a series arrangement, the voltage of each battery adds together, while the capacity in ampere-hours remains determined by the individual cells used.
| Battery Type | Voltage per Cell | Combined Nominal Voltage |
|---|---|---|
| AAA Alkaline | 1.5V | 4.5V |
| AAA NiMH Rechargeable | 1.2V | 3.6V |
| AAA NiCd Rechargeable | 1.2V | 3.6V |
Important: The holder does not contain a voltage regulator or converter. The actual output voltage depends on the battery chemistry, charge condition and load. Ensure the connected device supports the selected battery type and its corresponding voltage range.
ON/OFF Switch & Electrical Connections
The holder includes an integrated ON/OFF switch for controlling power to the connected electronic circuit. This allows the battery supply to be switched on or off without physically removing the batteries.
- Power Control: Use the built-in switch to control the battery supply to the connected project.
- Wire Length: Approximately 15cm of pre-attached cable is provided.
- Tinned Ends: Approximately 5mm of each wire end is tinned for convenient soldering and connection.
- Series Output: The three internal battery positions provide a combined series voltage.
- Circuit Compatibility: Connect only to equipment designed for the holder’s actual output voltage and current requirements.
The supplier does not specify wire polarity, conductor gauge, maximum current or switch rating. Confirm the actual lead polarity and electrical ratings before integrating the holder into a circuit.
Protective Enclosure & Battery Installation
The enclosed design features a removable sliding cover secured by a small head screw. This arrangement helps keep the installed AAA batteries contained within the holder and provides a more organised assembly than an open battery holder.
- Battery Loading: Insert three AAA cells into their designated positions, following the polarity markings inside the holder.
- Sliding Cover: Close the enclosure using the supplied sliding cover.
- Screw Locking: Secure the cover using its small head screw.
- Compact Housing: The plastic enclosure keeps the battery arrangement contained within a defined case.
- External Wiring: Use the attached wire leads to connect the holder to the intended electronic circuit.

Connection & Operating Recommendations
- Use Matching Batteries: Install three AAA cells of the same chemistry, type and preferably similar charge condition.
- Observe Polarity: Follow the positive (+) and negative (−) markings inside the battery compartment.
- Check Supply Voltage: Confirm that the connected device supports 4.5V nominal alkaline or 3.6V nominal rechargeable battery operation, as applicable.
- Confirm Wire Polarity: Identify the positive and negative output leads before connecting them to the circuit.
- Use Suitable Current Ratings: Ensure the connected load is within the ratings of the holder contacts, wires and integrated switch.
- Secure the Cover: Close the sliding cover and tighten the locking screw appropriately after installing the batteries.
- Use the Power Switch: Switch off the battery supply when the connected project is not in use.
- Prevent Short Circuits: Keep exposed wire ends and battery contacts away from unintended conductive connections.
- Replace Cells Together: Replace all three batteries together rather than mixing old and new cells or different battery chemistries.
