Rechargeable Battery for a Greener Environment

According to the Environmental Protection Agency (EPA) tons of dead alkaline batteries are thrown into the landfills yearly. These dead batteries come from electronic toys and games, portable audio equipment and gadgets and make up almost 20% of the hazardous materials the environment. During normal use, alkaline batteries are sealed making them safe to use but when they are degraded in the landfills, they result into toxins leaching into the ground. A better option to create a greener environment is Rechargeable battery.

Why is the Rechargeable battery a better option?

A Rechargeable battery when charged properly can be used for hundreds or even thousands of times. While the initial cost of the battery is relatively higher than non-rechargeable batteries, it becomes more cost effective in the long run because it can be used over and over again. One of the most common types of Rechargeable battery in the market today is the lithium-ion battery that has a longer life and holds charge better. Lithium-ion battery is different from Lithium battery that is not rechargeable but has a longer life. A Lithium battery is typically found in devices like pacemakers and other electronic medical devices. Lithium batteries can also be used on ordinary devices like cameras and clocks, but they are more expensive even if they minimize the need for battery replacements. Another example of Rechargeable battery is nickel-metal hydride (NiMH) that boosts of higher capacity but with shorter shelf life. It is important to ensure that the NiMH battery is not over-charged because it could lead to a decreased capacity.

Important factors to consider when buying rechargeable batteries

When buying rechargeable batteries for replacement it is critical to consider size, power and warranty. It is important to check whether the physical dimensions of the rechargeable batteries are similar to the battery being replaced. It is also important to consider the required power for replacement and the warranty provided by the manufacturer to ensure that you will be satisfied with the replacement. Increasing brand competition among manufacturers have made rechargeable batteries available with new improved specs and are rechargeable for 1,500 times without reacting to changes in temperature.

Reasons why some rechargeable batteries fail

There are several reasons why rechargeable batteries fail. Usually excessive heat can cause corrosion while extreme cold can sometimes put a heavier drain on rechargeable batteries. Overcharging usually results into overheating and causes the battery to depreciate. If the battery is not securely held down, vibrations can shed the active material from the battery’s plate grids. Other possible reasons for failure of your rechargeable batteries are corroded terminals, sulfation due to inactivity or electrical shorts. Since rechargeable batteries are made from different compositions, this can also influence depreciation.

In order to prolong the life of the rechargeable batteries, it is important to store them fully charged to prevent freezing. The best area to store the batteries is a dry, cool and well ventilated place that is away from the reach of children and pets. Check the level of charge every 30 to 45 days.
