I believe that AA batteries are rated at 1.5 volts each, so if you were to take 6 of them and wire them together in series that would produce a circuit that's pushing 9 volts.
But recharge AA batteries are only 1.2 volts per unit so a little lower voltage will be the result. I think most devices will still work on the lower voltage. Also these batteries will never last as long as the regular dry cell.
you need 3 x AAA batteries. Also it's better to use alkaline batteries not rechargeable batteries.
Most wireless headphones will have batteries so no they wont need charging unless you have rechargeable batteries
They are effective in some ways, but the one setback for this is that you will need to use electricity to recharge the batteries when they run out. However, rechargeable batteries are the best type out there.
???????????????????? What exactly is your question? If you are asking if Ni-Cd batteries are rechargeable, then the answer is yes, although you need be sure to have the appropriate charger for them, just as with NiMH batteries.
It will depend on what battery you need. I use rechargeable AAA and AA batteries for my lights. Bike computer batteries will vary depending on the type used.
If you need 4 AA batteries, buy the Duracell. If you only need two, buy the Ray-o-Vac, it's cheaper.
The Roomba or the carpet cleaning robot has various models, some take traditional batteries but others come with rechargeable batteries to avoid the extra costs in constantly replacing batteries on this handy household tool.
Three main reasons: If we tried to use rechargeable batteries, we'd still need to have another source of electric energy available to charge the batteries from If we tried to use primary AKA non-rechargeable batteries, we'd have to keep making HUGE batteries, shipping them, and then scrapping them once they're used up - which'd be fairly soon. Very costly and not environmentally friendly. Batteries deliver DC - direct current - which is harder to change voltage in, which makes it more difficult to transfer.
A few topics to consider about batteries (there are many different kinds)- what changes in batteries were needed to make electric cars feasible- are rechargeable batteries better than replaceable batteries- how are batteries sized for different usesOf course, you should pick a topic that you are familiar with or can research to find good information.
