If you use batteries a lot but do not always have the means to recharge them then you will probably use disposable batteries. Although it can cost a lot more to use disposable batteries, they are very convenient. They are also usually more powerful and longer lasting than rechargeable batteries. There are a lot of different kinds of batteries. Zinc carbon batteries are very inexpensive, they are usually used in equipment that does not need a lot of power. But although they are not that powerful in the right situation they are very useful. If you need a bit more power there are Zinc chloride batteries. Zinc chloride batteries are used in the same way as the zinc carbon batteries but have a bit more power.
There are very small batteries for such things as hearing aids and watches. Zinc batteries are used in hearing aids and there are mercury batteries for watches. One of the more recent battery innovations is the lithium battery. Although they were first made in 1912 they were not used that much until portable goods such as walkmans were widely used. But the fact that they are being used more means that the batteries that we have now are a lot more powerful and better than ever. There have been a lot of technical advances in the field of batteries and there are going to be a lot more soon with some great new innovations on the way. Soon the old disposable batteries will not be used as much as they are now.
One of the main problems with disposable batteries is the environment. The fact they will make an impact on the environment is unavoidable. This due to the fact that you will always have to throw away the batteries when they are finished. But there are companies that are making batteries that are more friendly to the environment. This does not mean that they are not going to affect the environment, but they will just have lees impact on it. If you can use them, it is generally better to use the rechargeable batteries than the disposable ones. But if you have to use disposable ones then it is a good idea to try to find the more environmentally friendly option, there are a lot around now. Also if you are able to use the rechargeable batteries then you will save a lot of money as well.
