2× AAA Battery Holder, Series Output 3V / 2.4V

Description

2× AAA Battery Holder Wired in Series

This compact holder takes two AAA batteries and provides a supply for small electronic circuits, sensors, toys and portable projects. The two cells are wired in series, so their voltages add.

• Two AAA battery slots
• Series connection (2S)
• Nominal output: 3V with two alkaline cells or 2.4V with two NiMH cells
• Positive and negative output leads
• No built-in voltage regulator or charging circuit
• Batteries are not included

Series connection

Voltage adds in series, while capacity remains approximately that of one cell.

2 piles alcalines :
1,5 V + 1,5 V = 3 V

2 accus Ni-MH :
1,2 V + 1,2 V = 2,4 V

For example, two 800mAh NiMH cells form a pack rated about 2.4V and 800mAh, not 1600mAh.

Use

1. Use two matching AAA cells.
2. Check their condition and voltage.
3. Observe the + and − markings in each slot.
4. Insert the cells with the indicated polarity.
5. Measure the total output voltage with a multimeter.
6. Connect positive to circuit VCC and negative to GND.
7. Add a switch if needed.

Safety notes

• Do not mix alkaline and NiMH cells.
• Use cells of the same type, capacity and similar condition; do not pair a new cell with a used one.
• Never recharge alkaline batteries. Charge NiMH cells only with a suitable NiMH charger.
• Observe polarity and do not short-circuit the output.
• Remove the cells for long-term storage.

Example applications

Small robots and toys, compatible 3V circuits, suitable LED lighting, alarms, buzzers, standalone sensors, small controllers and low-voltage prototypes.
