batteries

To use the LEDs without a resistor, you connect all 3 in parallel across 3 V (a 3.3 V coin cell battery, or 2xAA batteries in series). Any higher voltage will burn the LEDs out. Any lower and they probably won''t light up. Similarily, you could probably get away with connecting 3 LEDs in series across a 9V battery, but I wouldn''t recommend it

6 FAQs about [3v connected in series to form a 9v battery pack]

What is a 9v battery?

What is the difference between a 9V and a AA battery?

For an alkaline 9V battery these have a high Equivilant Series Resistance compared to say AA batteries. Leds will draw a forward current at a given forward voltage. If the voltage is lower than your target current, then it van be connected without any other type of current restriction.

What if a 3V and 9V battery were wired in parallel?

For example if a 3V and a 9V battery were wired in parallel the output voltage would be 6V ( 9+3 divided by 2 ) however the current will be total amperage of all batteries in the circuit (minus any losses). In this case we can see that 89.6 muA and 70.6 muA produced a collective current of 138.4 muA or about 21.6 muA below our expect 160 muA.

How do you connect a battery in series?

When connecting batteries in series, the general advice is to use batteries of the same ratings and the same make and model in order to minimize differences in exact voltage and amperage. Note, we say ‘minimize’, because even batteries coming off the same production line can vary slightly in these measurements. Another factor is battery age.

Can you connect different rated batteries in series?

Very large differences can result in explosions. This is why the short answer to connecting differently rated batteries in series is “Don’t”. When connecting batteries in series, the general advice is to use batteries of the same ratings and the same make and model in order to minimize differences in exact voltage and amperage.

Is a 9v battery a borderline voltage?

The LEDs you chose have a forward voltage specified at 3.0V-3.2V, so a 9V battery would be borderline. You'd have to get them and measure the actual forward voltage. Many white LEDs are less than 3 volts, more like 2.8v typical. If the actual Vf is below 3V then the current needs to be regulated.
