you put de-ionised water in it, then charge it. this turns to acid as you charge it up.
if you're in a rush i think specialist battery shops can top it up with acid for you, but the water is only pennies from places like halfords. dont use tap water, its got too much muck in it.
i guess you got the battery mail order, and they couldnt ship you the acid? last time i bought a battery that wasnt sealed i got a "six-pack" of little polyethylene bottles with the sulphuric acid in, looked like my wifes contact lens solution. couldve been hours of fun right there, but i love her too much

Many moons ago when I was a courier.........
....One guy was asking the same question........
So the other guys being complete and utter tw@ts persuaded this one guy that instead of hunting aound for acid/water that they all peed into their batteries after a good night out as the alcohol made the urine very acidic.
Poor guy actually believed them.......
........ And had to buy a new battery!!!!!!!

How does that happen?

Same way as any concentrated liquid can be turned into a powder (or Ge)l and then by adding water you dilute it again.
The acids's there, just not in liquid form.

well, put simply,
How does that happen?
each cell (more than one cell is a battery of cells, which is why they are called "batteries") contains a plate[electrode] each of lead and lead oxide. these are immersed in a fluid[electrolyte]. in a charged state this is a solution of 37% sulphuric acid. as you use the battery the electrodes gradually absorb the sulphur and become lead sulphate, leaving the electrolyte as water. more or less(dont bother drinking it)
you reverse the process (or start it with a new battery+de-ionised water) when you put a current through the electrolyte with your charger and the electrodes give up the sulphur again.
its the chemical reaction between dissimilar metals immersed in the acid that gives us the current.
a charging cell gives off free hydrogen and oxygen gas from the electrolysis of water, and can explode when your regulator fries and tries to put more than 14.4V through it(gassing point, sodastream time!), and because a discharged battery in poor condition contains mostly water they always bugger up in the winter because the electrolyte freezes.
by using various PH electrolyte and wildly dissimilar electrodes a far more powerful battery can be made but lead/acid batteries are very reliable and cheap. bollocks to the environment though.
ok?
