# Replace some LEDs with Diodes [closed]

I have a COTS solar battery charger that has a number of different LEDs identifying the battery level, if its charging, etc. Its going to live in the shed, so 99% of the time no one will see its pretty array of lights. Would it be OK to replace these LEDs with diodes and would it save any electric? Thanks in advance.

• No, diodes have different forward voltages than LEDs. But maybe you can just omit the LEDs? – JimmyB Jan 30 '16 at 21:18

For example, a 3.3V circuit driving a 2.4V LED to 7.5mA would use a 120$\Omega$ resistor. If you replace the 2.4V LED with a 0.7V diode it will draw almost 22mA or almost 3x the current (and therefore, since it's all supplied by 3.3V, almost 3x the power, and over a given time period, 3x the energy).
