There is a big debate as to whether rechargeable batteries or single use batteries are better. To work this out you need to understand what better actually means, are they better because of their price, or are they better because you can use them over and over again.
This blog will delve deeper into the discussion as to which type of battery is better and answer some of the many conundrums and conceptions people have about both rechargeable and single use batteries.
Are Rechargeable Batteries Better For The Environment?
There are several things to consider here, some of which are undeniably better for the environment. Rechargeable batteries will help to reduce the amount of waste packaging and the number of batteries that are disposed of, as if used correctly, they can last over 100 times longer than standard disposable batteries.
Rechargeable batteries do though require additional energy to charge, and if you are using them in very high demand applications, you could find you are using a lot of energy to charge them.
There are some rechargeable batteries that are being produced using recycled materials, which will further reduce their impact on the environment.
Throw away disposable batteries on the other hand, do have a lasting impact on the environment. There could be as many as 100 primary batteries thrown away for every 1 rechargeable battery, which would have such a huge impact on the total number of batteries being disposed of.
Why Are Rechargeable Batteries So Expensive?
As you will need to initially purchase a batter charger alongside the rechargeable batteries, it can appear to be a very expensive outlay, potentially up to 4 or 5 times more expensive in total than single use batteries. That being said though, it is only an initial purchase, you do not need to keep buying new chargers every time you need additional batteries. The chargers will be compatible with any additional rechargeable batteries you purchase in the future or you already own.
The batteries themselves are slightly more expensive than primary disposable batteries too, but that is because during the manufacturing process, more expensive materials are used. They can be up to 3 or 4 times more expensive, but the technology inside them, allows for them to be charged and discharged hundreds of times.
Should I Buy Cheap Single Use Batteries?
Buying single use batteries is very common for many of us, particularly those of us with children. They are also always strategically positioned in supermarkets so that you and your children do not forget them. But should you buy them? and which should you opt for?
Single use batteries are much cheaper than their rechargeable counter parts and offer in that moment a cheaper alternative. Most stores will have the premium brands such as Duracell, Panasonic and Energiser. Some stores will also have cheaper brands, or own brand batteries that are usually marketed as "Long life" or other words that point towards the length of usage and quality.
The own brand and cheaper brands of batteries usually come in packets of 8 or 10 and are the same price as the premium brands for just 4. While you may be getting more individual batteries for your money, you may find yourself having to replace them sooner than with the premium branded batteries.
Which Batteries Last Longer?
Both types of batteries claim to last longer than each other, but what does last longer actually mean?
Single use batteries have a much longer initial shelf life than rechargeable batteries. Some primary batteries will work up to 10 years after manufacturing date, whereas some rechargeable batteries will need charging after 12 months of purchase if they haven't been used.
Many single use batteries will also last longer on a single charge than a rechargeable battery will as rechargeable batteries are designed to be constantly charged and discharged in a cyclic process. This means that rechargeable batteries can be used over and over again, so they do technically last longer, but will require a series of charges, which would interrupt the use of the application.
So, When Should I Use Rechargeable Batteries?
Rechargeable batteries are best to be used in devices and applications that require quick bursts of energy over a short period of time, where there is time afterwards to charge the batteries before use again.
Uses can include remote controlled cars, power tools, digital cameras, cordless phones and game console controllers.
We would not recommend using rechargeable batteries in applications that involve long and low power usages, as it could result in premature misfunctioning of the device, such as a clock losing time.
And When Should I Use Disposable Batteries
Disposable batteries are very good at being used for long periods of time in devices that require a low amount of power.
They are also great as emergency batteries as unlike rechargeable batteries they do not need to be charged ready for use.
Uses can include alarm and wall clocks, television remote controls, smoke alarms, torches, portable lights and thermometers.
Rechargeable Batteries Pros and Cons
| Pros | Cons |
| Environmentally Friendly | High Initial Cost |
| Use Repeatedly | Requires Charging and Maintenance |
| Reduces Waste Packaging | Not Ideal For Emergency Situations |
Single Use Batteries Pros and Cons
| Pros | Cons |
| Low Initial Cost | Cannot Be Recharged and Reused |
| No Charging Necessary | Not Environmentally Friendly |
| Ideal For Emergency Situations | Increases Waste Packaging |
So Which Battery Is Best?
As you can see, both types of batteries have their benefits and flaws. Battery Group recommends having both types of battery in your home or at work and using them in their correct applications. This is the best way to achieve both battery harmony and minimising overspending on disposable batteries.
Remember though, to charge your rechargeable batteries with a battery charger after you have used them, otherwise, when you come to use them next time, they will not work.
