To make the tool more versatile. You can go places there is no electricity.
Unless specifically stated on the package, power toys can be used with rechargeable batteries. If there is a question about a specific toy, it might be wise to call the manufacturer. Rechargeable batteries are designed to 'go anywhere a regular battery goes".
AA rechargeable batteries are batteries that are not disposable. That is, once the power is drained, you can recharge them and use them again and again. I find these quite useful when used in my video game console.
these are rechargeable batteries used in cell fones
The most common size batteries are AA. These batteries are used for remotes, digital cameras and a variety of children's toys. It's always a bad situation when you find yourself out of batteries when you need them a good solution for making sure this doesn't happen is to keep a constant rotation of rechargeable batteries available. When ever you replace your rechargeable batteries take the dead batteries and put them in the charger so they are ready to power the next device that runs out of power.
No, I don't think rechargeable batteries are better than the regular batteries. I have always used the regular batteries and they have always worked very well for me. I know some people that has used rechargeable batteries and said that they don't stay charged for very long.
No. They are designed to be used then discarded.
This depends on what you are using the batteries for. If you are using a device that is used on a regular basis, rechargeable batteries are the best choice. If it is a device that is rarely used, regular batteries would be the best choice.
Regular batteries will power a solar light until they run out of power. But regular batteries can't be charged from the solar cells unless rechargeable batteries are used instead. There is also a bit of circuitry involved.
There are some rechargeable portable DVD players where you can use rechargeable batteries, they cannot be used in every portable DVD player because at some point the batteries start to slow down.
yes there is. There are a few differences between the two. Some are than lithium ion batteries are rechargable whilst lithium batteries cannot be recharged. Also lithium batteries use lithium in pure forms whilst lithium ion batteries use lithium compounds to produce their charge. Lithium batteries can be seen in items like watches. An example of a lithium ion battery is a mobile phone battery.
Nickel
Primary cells are designed to be used once and discarded. Secondary cells are, by definition, rechargeable batteries, and as such are the kind used in rechargeable torches (or flashlights, for you American types).
