Over the past fifty years, many of the products we use have increasingly become powered by rechargeable batteries—from the lead acid batteries in our cars and other motorized vehicles, to the variety of Ni-MH and lithium-ion rechargeable batteries powering our digital cameras, laptops, and other electronic devices.
Choosing between rechargeable and disposable batteries can be frustrating. Often the frustration stems from not knowing which will work better. With different kinds of more efficient batteries appearing on the scene, such as the lithium-ion rechargeable battery, choosing can be a bit of a headache.
But in reality, there are only two main factors to consider. Battery Price Rechargeable batteries are usually more expensive, at least initially. Since rechargeable batteries can be charged many times over after the initial purchase, it is reasonable that rechargeable batteries comes with a much higher price tag than disposable non-rechargeable batteries.
Having a lower initial cash outlay makes it one of the reasons that some consumers choose to purchase disposable batteries. But in the long run, the batteries that you can recharge are significantly more cost effective, often providing you with a hundreds or more hours of use than their disposable counterparts. The lithium-ion rechargeable battery for example, has proven to be efficient, especially in consumer electronics.
Battery Life Disposable batteries last longer than rechargeable batteries, but only initially. The initial charge of a disposable battery tends to make it last significantly longer than its counterpart in most applications, making it the better buy at first glance.
When it comes to rechargeable batteries, they last much longer as you can recharge them. Rechargeable Batteries Then? Not Always.
Consider the application first. While the verdict may seem to be a no-brainer inclination in favor of the rechargeable battery, a case can be made for the usefulness of disposable batteries. It really depends on application. For example, non-rechargeable batteries can be the perfect choice for low-drain products.
Low-drain devices use only occasional power or very low power over a longer period of time. Smoke detectors, remote controls, and wall clocks are just few of devices that could benefit from disposable alkaline batteries. Rechargeable batteries can be the ideal choice for high-drain gadgets and electronics that quickly drain a lot of energy.
Since these batteries can be easily recharged, you will be ridden of the hassle of constantly purchasing new batteries. Lithium-ion rechargeable batteries, which are commonly used to power portable consumer electronics, are a better choice for such devices, and will give you more bang for your buck.
The chemical reaction in the battery causes a build up of electrons at the anode. These electrons really want to go to the cathode to balance it out but the electrolyte stops them.
They go along whatever path you supply that connects the anode and cathode, like when you put the battery in a toy. Over time, anode and cathode under go chemical change and supply no more electrons. For alkaline batteries, this chemical change creates a little bit of hydrogen gas. That gas needs to go somewhere, which is why batteries sometimes leak.
After a certain time, the pressure builds and the gas needs to escape. Batteries leak because they are being drained phantom drain and age. A quick takeaway here is that if you are putting anything in storage, take out the batteries. OK, now you know about batteries. If electricity were like water flowing through a hose, the amperage is the diameter of the hose. They differ on amperage. As a result, they contain different Watt-hours Watts is voltage time amperage — or total amount of energy.
For the curious, this is a table listing all types and how much energy they contain. Test each one to find out which one is the low man on the totem pole, then just replace him. Coin or button cells are named so because of their shape and size.
Those that are thinner and resemble coins are known as coin cells, while thicker ones are called buttons because of them look like so. These batteries come in sizes ranging from 5 to 25mm in diameter. They measure 1 to 6 mm in height. They are single cells used as primary batteries, which means they are used once and disposed of.
There are three main categories of coin cells: alkaline, lithium, and silver oxide. Physically, they are interchangeable. You may not even be able to tell one type from another unless you take a closer look. However, they are different in terms of chemistries. Some chemistries are more preferred to others. It all depends on the usage and specifications. For instance, speakers and cameras with high drain features come with varying needs for remote power. You need to understand how coin batteries work to get the best.
If you think lithium coin batteries are the best, then you are right. Because they have battery life more twice that of alkaline batteries, they are more costly. Nevertheless, the difference is a matter of voltages. Lithium coin batteries have a nominal voltage of 3V while silver batteries are at 1. This means the former is much stronger in terms of power output.
Your choice depends on the device you are using. If you are going to replace the battery, look at the specifications of the current ones in the device, and compare it with the new ones. That way, you will get the exact power to work for your device.
