This depends on the capacity of the battery and how much current is used to recharge it. Your best choice would be to get a smart charger that automatically shuts off when the charge is complete.
I am no expert but until someone answers for sure Im going to help you out and say that yes a 24volt charger will charge a battery slightly. You will in no way get up to 36 volts or the right amounts of amps (volts are like how fast water can come out of a pipe, and amps are like how much water is actually coming out, wide pipe=lots of water; small pipe=less water. but moving both at same speed.) So yes Im pretty sure your 36v batt will capture some electricity and bring it back to mid-low volts (5-15) but you should really find a 36v charger for you 36v battery. if you find this charger keep in mind that the lower the amp rating of the charger (say 1amp -3amp) will take longer to charge the battery but its better for the battery. Higher amps are for fast charges in an emergency and will lower battery performance and life over time.
which version of the ipod nano?
Is the wall charger one by Samsung, or a third party? If it's the latter, I would suggest either getting a Samsung charger, or finding a charger that can charge 2.1A. 1A capable chargers are passable, but expert the output to be much slower. In any case, turning off the tablet and allowing it to charge should charge faster than when it's on. Now even if you get a better charger and your Samsung Galaxy Tab 3 is still losing charge faster than getting charged, you can look at getting the app like Battery Stats Plus (it's free) and it can tell you what's causing the drain. There could be an app that's constantly awake that's causing excessive draining. Worse case, there's the possibility that the battery is no longer functioning properly. That then may require battery replacement.
No, you can not; to connect your iPod to another iTunes, you have to put in their password and connect your iPod to their iTunes. When you do that it will ask if you want to "sync and erase" or "cancel". If you click on "Sync and erase" then all of you songs will be gone and you will have their songs because you can not fuse two accounts. I would recommend that if you and the other person with the iTunes, (if your main reason for wanting to sync your iPod with his/hers is to exchange music) then i suggest that you either use a CD (slow method) or a Flash drive (much faster).
it is not new but, i think it is 3hrs full charge.
Whether you have just started using your iPod or are looking to make the battery last longer than normal, consider the following tips: Charge the battery only when it runs out. Charging it too much can actually result in a shorter battery life. Keep your iPod at room temperature. Leaving your iPod out in the cold can damage it. Turn off your iPod when unattended, as leaving it on can quickly drain the battery.
it is 12v
An iPod does not have monthly payments. Most people pay the price for the device up front, and then the only money going to it is from iTunes, and electricity for charging. A study showed that an iPod costs only $6 annually (yearly) to charge.
you cant just buy a battery you gotta buy a new ipod
yes, it does, but it doesn't affect the battery too much.
Only running cost is the cost of electricity consumed to charge the battery through a charger. How many units of electricity is consumed will depend on the capacity of battery, efficiency of the charger (and so losses of energy in the charger in form of heat and radiation). You can estimate the power consumed by the voltage and wattage rating of the charger and how long it takes to charge the phone battery fully. - Neeraj Sharma
It depends what iPod. If you know what iPod you're talking about then you will probably find it on the apple website :)
About an hour and a half.
It's either out of battery because you didn't charge it or its broken. If you for sure charged it recently and you had a lot of battery left, then its probably broken. It was most likely dropped too much or a liquid got into the engineering.
It uses a little extra battery power, but not much.
The battery stores just so much electricity. The lights use this electricity. Sooner or later the supply is depleted.
