Nope, will not make a difference. usually new batteries are filled with acid which makes the cell charge initially but a new battery needs to be deep charged before the first use. But honestly it will not make a difference. Charged or not you can use it as long as you do not drain it completely on your first use.
Thanks for the reply. How do they keep it charged by still keeping the cells new? And for how long have they been charged for? I mean usually you give an advance payment to the shop guy and they charge it for a single day or a couple of hours for you.
Ummm actually. It should, and it will make a difference.
The theory of Lead-Acid batteries can be traced back to simple, high school chemistry. It is nothing but a reversible, electrolytic cell, where by each Lead cell has the capacity to hold 2.1V, and the current depends on the size of the cell.
It is noteworthy, of course, that batteries can't
'produce' or
'generate' energy, they can only
store it for later use.
Without acid, there would be no way to 'charge' the cells in the first place, or, in easier terms, there would be no 'charge' in the battery. The cells can only give back what they have retained.
The acid, or, the 'electrolyte' is what causes the transport of energy to the system. Without the acid, there can't be any flow of current. Without any flow of current, the lead plates are as good as poisonous rocks.
So, in short, when you have a 'pre charged' battery, the only way for that to happen is if they have either added the acid already, or, if they add the acid, very quickly burst charge it for a few minutes at a very high current and surge the cells, both of which are bad for your battery.
Once you add acid to the battery, even if it is sitting there unconnected, the process of its deterioration has begun
even if you don't use it. A chemical process called 'Sulfation' begins on the plates, which is why your batteries eventually become less efficient, and, eventually die. Of course, this process is much more appreciable when you are putting the battery through charge-discharge cycles (sulfation is primarily in the latter of the two phases), however, the battery does start to age.
So, if you have a battery with pre added acid, it's going to die out sooner and be less efficient more quickly.
And, if you have a 'pre charged' battery whereby they quickly charge the battery and give it to you, then, again that's not good for your battery. Higher currents will cause (much) higher temperatures in your cells, which will lead to not only water boilup, but also, high temperatures very adversely affect the battery. And, of course, you won't be fully charging the battery (which is what should be done with new batteries), you would only be providing a fraction of it with current and then trying to get to the top, reducing the efficiency drastically.
As a rule of the thumb, the
maximum charge rate a lead-acid battery should be given is C/5, and the recommended charge rate is C/10, generally. We tend to charge them much faster, in our UPS's, by the way, which leads to shorter battery lives.
(C/5 means max charge should be 1/5 x Ampere rating of battery)
(Or in even simpler terms, the recommended charge rate for lead-acid batteries would take the battery TEN times as much time to charge is it took to discharge).
