AAA battery holder with wire leads, 1–4 cells

Product detailed description

The plastic AAA battery holder with wire leads is a simple way to power Arduino, ESP32, LEDs, or other small electronic DIY projects using AAA batteries or NiMH rechargeable cells. The cells are connected in series within the holder, meaning the output voltage corresponds to the sum of the voltages of all inserted cells. The red wire is positive (+), and the black wire is negative (−). Choose the holder based on your required voltage – options range from 1 to 4 cells arranged in a single row.

Specifications:

• Cell type: AAA (mini-pencil, R03 / LR03 / HR03)
• Cell connection: series
• Leads: 2 wires – red (+), black (−), bare ends without connector
• Material: plastic, spring and tab contacts
• Cover / switch: no (open holder)
• Variants:
  • 1×AAA: 1.5 V (alkaline) / 1.2 V (NiMH)
  • 2×AAA: 3 V (alkaline) / 2.4 V (NiMH)
  • 3×AAA: 4.5 V (alkaline) / 3.6 V (NiMH)
  • 4×AAA: 6 V (alkaline) / 4.8 V (NiMH)

Package contents:

• 1× AAA battery holder with wire leads (according to the selected variant)

Note:

• Batteries are not included in the package.
• When inserting cells, observe the polarity marked in the holder. Do not mix old and new cells, or different types (alkaline and NiMH), in a single holder.
• Beware of short-circuiting the bare wire ends – in the event of a short circuit, both the batteries and wires can overheat severely.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
