Yes, well maybe. Not sure on jell cells. When you run current threw water though there is electrolysis and it splits into O2 and H2.
Not fully, but these days come more than half charged, yes.
The benefits of using Eneloop batteries are that they have a long life. Similarly, these batteries come pre-charged and energized. They can be recharged and recycled, often saving the owner money.
No - for safety reasons, all new phones are shipped with their batteries fully discharged !
No. New smartphones usually come with batteries pre-charged up to 50% only. Usually so the store can set it up for the customer if they require.
Short Answer: a partially positive hydrogen atom gets attracted to a partially negatively charged atom. _______________________ Take water for example. There is an Oxygen atom (which pulls electrons towards it-- making it partially negative) There are also two hydrogen atoms. The (negatively charged) electron on each H atom is being pulled towards the O atom, making the Hydrogen partially positive. Now, when two water molecules come together, the partially positively charged H's on one water molecule are attracted to the partially negatively charged O's on the other molecule. This attraction between oppositely charged atoms on different molecules creates a 'hydrogen bond'.
To match the need of the device being powered.
The best kind of rechargeable batteries are the hybrid Eneloop batteries because they come fully charged and they have an extensive life. They can hold a charge 6 months and sometimes even longer and are worth the cost in the long run.

If you allow it to discharge, then it becomes useless, so you have to recharge it. Some batteries (e.g. for torches) don't have to be charged because their internal chemistry is such that they come already 'full'. But once they discharge then you have to throw them away.
no electronic Nerf guns come with batteries ...sorry :-(
Most new batteries should come charged, unless the new battery is actually one that has been sitting on the shelf for a quite a while. If you're having problems starting, you might have a problem with the starter itself. Good Luck!!!
Sanyo Eneloop has the best rating on www.bestrechargeablebatteries.org. They come fully charged and retain their charge longer than most other rechargeable batteries.
