Batteries are used everywhere in our daily lives. From vehicles to your kitchen appliances to your mobile phones everything uses battery. We need to know how to use these batteries effectively and make optimum use of the same. Regulating their use is also of great concern. We should also know how to conserve these batteries from getting drained and increase their life span.
- Battery holders are devices with one or more compartments to hold batteries. These can accommodate both wet and dry cells and have different arrangements for them. In the case of dry cells the holder is to make connections with the battery terminals but in the case of wet cells cables are connected to the battery terminals.
- These can be either housing-shaped plastic cases or can be a plastic case of compartments that can be attached to one another with double tapes or screws etc. in many kinds of battery these have lids that can protect the battery or are often sealed to prevent damage. Surface mount feet, wire leads, pins and solders are used to make external connections.
- Knowledge of the whereabouts of the larger product is very necessary for the battery holder. The age range, ease of battery exchange and other human factors like physical conditions are considered important in the designing of these battery holders. Many battery holders are made from polypropylene or nylon bodies.
- Fixed contacts are often for lesser price but are vulnerable to the disintegration of electrical connections. Fixed and flexible contacts together make a great combination. A flexible contact permits the cell for a slight expansion on discharge, and internals chemicals increase in volume. Multiple fingers that touch the cathode and anode which allows multiple direction movements without any loss of electrical connection are available only in flexible contacts.
- There are many environmental issues regarding these battery holders. These have become a great topic of discussion because of its contribution in global warming and the immense generation of e waste. These cell holders are also used in mobile phones and laptops which also completely contribute to the issue of the generation of e waste.
- E waste is very dangerous for our environment because it is non biodegradable and sometimes can be radio active in nature and can harm the environment in many ways. Major contributors of e waste are the cell phones, batteries, battery holders, laptops, chargers and remotes etc. it has become a worldwide concern because of the increasing land pollution that these waste create.
The best measure to take care of this generation of e-waste is by reducing the use of such materials, reusing them by repairing them and getting them fixed until and unless they get damaged beyond repair, and also recycling them. Proper disposal is also what can help in controlling this.
