A lead acid cell has an off charge/no load voltage of 2.2 volts, so that 12 cells in series will have a voltage of 26.4 volts. When you float this across a charging supply, standard practice is to increase the voltage to 2.3 volts per cell, so that the total voltage becomes 27.6 volts.
Airplanes normally have a 27.6 volt DC system, and larger aircraft also have a 115 volt 400 Hz system. Also, rare these days, possibly a 115 volt wild frequency system.
Note that the so called 12 volt system in a car is actually 13.8 volts.
Higher acid / lower pH in limes
AnswerAccording to WikiPedia (http:/en.wikipedia.org/wiki/Rechargeable_battery), the nominal cell voltage of a Lead Acid wet-cell battery is 2.1 volts, this implies there are 6 cells in a 12 volt Lead Acid wet-cell battery.
A battery is basically 2 metals separated by acid (which is used as an electrolyte). All you have to do is to place 2 metal plates (made out of certain metals) inside the fruit, and connect them into an electric circle. You'll see it produces weak but noticeable voltage.
Perhaps it would be possible to replace an alkaline battery with a lead acid battery of the same voltage and current capacity. BUT the construction, size, and chemistry of the two types are totally different.
For lead-acid chemistry, as in a car battery, think 13.6 volts DC.
It depends on what the 6 cells are, but the battery voltage is just 6 times the cell voltage. In a car battery (lead-acid cells) - 12V In a dry-battery (zinc-carbon cells) - 9V
Leaking from where on the battery, the caps? If so the charging system may be over charging the battery and causing the acid to boil out. Could be a voltage regulator problem.
Each cell of a modern lead-acid battery should have an average voltage of about 2 volts but, depending on the cell's condition and state of charge, the exact voltage at any time may be somewhere in a range from about 1.8 volts (when it is almost fully discharged) and 2.25 volts when it is fully charged.
The voltage of a battery is determined by the chemistry inside it ... zinc/carbon, nickel-metal-hydride, lead-acid, lithium ion, etc. But nobody's expected to be able to look at it, or smell it, and know the voltage. If the voltage isn't printed on it, then you have to pull out the old voltmeter and measure it.

They produce hydrogen during charge and discharge.
Yes it can. since the juice inside the orange is citrid acid it can be like a battery and produce electricity.
