Description

Characteristics:
4 cells of 1.5 volts for a total of 6 volts and a current of 35-40 mA. The running time is approximately 30-35 minutes. To restore power to the battery to replace the salt water and ready for the new energy. This battery also works with water and salt, but the duration of the charge drops to 10-12 minutes, this is due because the salt dissolved in water has few active ions of sea water. The battery can be charged externally from 9 volts with only 4-5 minutes with a significant increase of the discharge time.
*The motor and leds that are seen in this video are 3 volts each. The motor used is a CD rom motor. In this experiment, I do not recommend using any type of motor for toys, they absorb too
much power.
