Rechargeable batteries do not have to be replaced as often as disposable batteries.
Rechargeable batteries can be used in place of disposable batteries to save money and help protect the environment from excessive waste. This type of battery can be charged many times to give batteries a much longer life than would otherwise be possible. They cost more money in the short run but, with use over time, can save consumers money.
Save Money
Rechargeable batteries save consumers money in the long run because they can be used many times without being replaced. These batteries come with a charger that allows consumers to plug them in once they run out of power. The cost of rechargeable batteries is higher than disposable batteries when they are first purchased, but the cost remains lower over time. Rechargeable batteries will slowly lose their power capacity as they are used repeatedly, but many varieties last for hundreds of charges before needing to be replaced.
Protect Environment
Batteries contain many chemicals and compounds that are unhealthy for the environment. Throwing batteries into the trash makes it possible for substances to eventually leak out of the batteries into landfills, which can then end up in water systems. Since rechargeable batteries do not have to be replaced as often as disposable batteries, they do less damage to the environment. Rechargeable batteries can be recycled once they lose power at many local recycling centers.
When to Use
Rechargeable batteries can be used in the same ways as ordinary disposable batteries. They are best suited for use in everyday electronic items such as television remotes, calculators and flashlights. There are different types of rechargeable batteries, some of which are made to work well with certain electronics, such as digital cameras. When choosing batteries, look at the package to find out the energy storage capacity, which helps to determine how long the batteries will stay charged.
When Not to Use
Rechargeable batteries should not be used in emergency items such as portable radios, emergency flashlights and medical equipment because they may self-discharge before the time that they are needed. They also are not helpful in low-power items that are difficult to reach, such as clocks or smoke detectors, because they may run out of a charge earlier than other types of batteries.
