SPIDER Automation | 2x AA Battery Holder | 3V Series | Transparent Case with ON/OFF Switch
The SPIDER Automation 2x AA Battery Holder with Cover and ON/OFF Switch is designed for electronic applications requiring a compact, replaceable-cell power source. It accommodates two AA batteries in a series configuration, combining their individual cell voltages into a single battery output.
The semi-transparent plastic enclosure features a removable sliding cover secured by a small locking screw. Integrated wire leads with pre-tinned ends simplify electrical integration, while the built-in ON/OFF switch provides direct manual control of the connected circuit’s power supply.
Technical Features & Enclosure Design
- Two-Cell Battery Compartment: Accommodates two standard AA batteries in a compact enclosure.
- Series Battery Arrangement: Combines the voltage of both cells to provide the required battery output.
- Semi-Transparent Housing: Provides visibility of the battery compartment and its contents.
- Sliding Cover Mechanism: Allows convenient battery insertion and replacement.
- Screw-Locking Cover: Helps secure the cover and retain the installed batteries.
- Integrated ON/OFF Switch: Provides manual switching control without requiring a separate external switch.
- Plastic Construction: Lightweight housing suitable for compact electronic equipment.
Electrical Configuration & Output Details
The holder connects two AA cells in series. The resulting nominal voltage depends on the chemistry of the installed batteries.
- Alkaline AA Batteries: Two 1.5V cells provide approximately 3V nominal.
- NiMH/NiCd AA Batteries: Two 1.2V cells provide approximately 2.4V nominal.
- Output Configuration: Series-connected battery supply.
- Power Control: Integrated ON/OFF switch.
- Voltage Regulation: No integrated voltage regulator or DC-DC conversion circuit.
The holder provides the direct battery-derived voltage rather than a regulated 3V output. Actual voltage varies with battery chemistry, charge condition and operating load. Select the connected device according to its permitted input-voltage range.
Wiring & Connection Details
The holder is equipped with integrated wire leads for connection to compatible circuit boards, terminal blocks and electronic assemblies. The pre-tinned wire ends simplify soldering and help reduce preparation time during installation.
- Output Leads: Integrated wire leads.
- Lead Length: Approximately 15cm.
- Wire End Preparation: Approximately 5mm pre-tinned at each end.
- Power Switching: Built-in ON/OFF switch.
- Connection Method: Soldered or otherwise suitably terminated wiring connections.

Connection & Operating Recommendations
For reliable operation, select batteries that match the voltage requirements of the connected circuit and use the integrated switch to control power during normal operation. The pre-tinned leads support straightforward electrical integration into compatible electronic assemblies.
- Install Matching Batteries: Use two AA cells of the same chemistry, voltage type and comparable charge condition for consistent series operation.
- Match the Circuit Voltage: Select the connected device according to the actual battery chemistry and resulting supply voltage rather than assuming every AA battery type provides the same output.
- Observe Lead Polarity: Connect the holder’s output leads to the corresponding positive and negative circuit terminals.
- Use the Integrated Switch: Turn the switch OFF before replacing batteries or carrying out wiring changes to the connected circuit.
- Make Secure Connections: Use suitable soldering practices and insulate exposed joints to prevent accidental short circuits.
- Secure the Battery Cover: Seat the sliding cover correctly and tighten its locking screw to help retain the batteries during use.
- Keep the Enclosure Dry: The plastic cover provides a physical enclosure but is not specified as waterproof or dustproof; avoid exposure to moisture and conductive contaminants.
