Electrical Configuration & Output Details
The holder connects its two AAA battery positions in a series configuration. In this arrangement, the voltage of the two installed cells is added together to provide the combined output voltage.
| Battery Chemistry | Nominal Voltage per Cell | Total Nominal Output |
|---|---|---|
| Alkaline AAA | 1.5V | 3V |
| NiMH / NiCd Rechargeable AAA | 1.2V | 2.4V |
Important: The actual output voltage depends on the battery chemistry and charge condition. The holder does not contain a voltage regulator or DC-DC converter. Use batteries of the same chemistry, voltage and compatible condition together.
Cover, Locking Screw & Battery Access
The battery compartment features a removable sliding cover that provides access to the two AAA battery positions. A small locking screw helps secure the cover after the batteries have been installed.
- Battery Replacement: The sliding cover allows convenient access when replacing the cells.
- Cover Retention: The locking screw helps prevent the cover from sliding open unintentionally.
- Battery Organization: The enclosure keeps both AAA cells arranged within a dedicated compartment.
- Enclosed Construction: Helps reduce direct exposure of the installed cells to dust and accidental contact. It is not specified as waterproof or dustproof.
ON/OFF Switch & Wire Connection
An integrated ON/OFF switch allows the user to manually control power to the connected electronic project without removing the batteries. The holder also includes pre-attached wires for connecting its battery output to a compatible circuit.
- Manual Power Control: The built-in switch provides convenient ON/OFF operation.
- 15cm Cable Length: Pre-attached leads provide flexibility when positioning the battery holder within a project enclosure.
