Probable effects of current (DC) flowing through a human body. Anything less than about 1mA is imperceptible. When we held the 9V to our tongue, about 1-2mA was flowing between the terminals. Because the tongue consists of a thin membrane with nerve endings near the surface, we could readily feel the current as it excited the nerves.
Making your own conector: Find a dead 9 volt battery. Tear its head off - aka, remove the terminals. This will push onto another battery and provide you with terminals. Note that on the connector which you are making the terminals are reversed. On the connector the round pole is negative (unlike on the battery).

Therefore it cannot charge a 9 volt battery. Also a 9 new 9 volt battery has more than 9 volts on the terminals. Your solar panel might charge a set of 4 c cells in series. BUT in all cases you need a charge controller to stop the battery from discharging into the solar panel when a cloud passes between the sun and the panel.
The nominal voltage of Li-ion batteries is 3.6V or 3.7V. NiMH and Lithium are the two most common types of rechargeable nine-volt batteries. Lithium batteries have double the capacity of NiMH batteries. The 9V NiMH battery lasts around four hours, whereas the rechargeable Lithium battery lasts 7 to 7.5 hours.
1 Answer. An ideal capacitor will instantly charge up to whatever voltage you connect it to.A practical capacitor will take some time to charge up owing to a finite internal resistance (referred to as equivalent series resistance or ESR),but eventually, it will still reach the source voltage.A practical capacitor also has a maximum voltage
