Batteries are now a part of everyday life. With the general purpose batteries supplying the power to household equipment and business machines. And with industrial and emergency lighting nickel cadmium battery packs working unseen in the background, it is easy to see how dependent we are on them. They have made many of our work tools and equipment portable and usable in places that it would not normally be possible. However, when not in use they should be stored away correctly and never left inside equipment for extended periods of time. This could cause the terminals to corrode as well as leakage and damage. And they should always be kept in a clean dry environment, so they are ready for use when needed. (continued below)
The rechargeable batteries are the better choice, you will save money as well as reduce the carbon footprint. The initial price may be slightly more but the rechargeable type will allow you to use them over and over. After the first few charges they will have paid for themselves and you will now be using them for free. By using rechargeable cells over and over it means far fewer are being produced, effectively reducing polution making them a more environmentally friendly choice.
The range of rechargeable batteries has grown and there is now a replacement for non-rechargeable in just about every type. They are more popular than ever before because of the long term economy and the flexibility of the products they power. Unfortunately, even rechargeable cells do not last forever. There are only so many times that they will discharge and then recharge. Rechargeable batteries charge in cycles, so many charges and so many discharges, for a limited number of times and will eventually have to be replaced.
The disposal and recycling of batteries is now a major concern because of the toxic chemicals they contain. It is no longer allowed to just throw them out with the rubbish. They have to be recycled to stop hazardous materials entering landfill sites and contaminating water and soil. They contain at least one of nine metals including cadmium, nickel, cobalt, lead, silver, zinc, mercury, manganese and lithium. Recycling them means less raw materials will have to be extracted from the ground, saving resources. And the thousands of tonnes of recovered metals and other materials can then be used to manufacture replacements.
