Rechargable batteries are best for instruments that draw lots of current, while disposables are best for lower power products.
It always seems that technology gets better and better and more advanced, but batteries don’t change very much. That’s the sad reality of batteries. They really haven’t improved much from years ago. Even so, you can make the best of your battery situation by deciding on between rechargeable or disposable batteries. Despite what some think, usually there are some situations where you probably will prefer disposables, and others where you will want to get rechargables.
What you should know when you’re choosing between rechargables and disposables is the fact that a disposable alkaline battery has about double the operating life as a rechargeable. It really will operate about two times as long as many rechargeable batteries. So you may want to choose to buy disposable batteries for the devices around your home that are low drain. That is, you will want to put disposable batteries in devices that don’t draw a good deal of current. Such devices would include your smoke detector, an alarm clock as well as the remote control for your TV.
You will find that these products will run for a years, in some cases, with disposable batteries. Also, as you are not needing to replace them frequently, you really are not costing yourself extra money by utilizing disposables in these situations.
For devices that use a lot of current, you will want to opt for rechargeable batteries that are nonalkaline. Some of the devices you will want to use with rechargables are DVD players, remote control cars along with other toys, as well as your power tools that are cordless. You will see that your rechargables will cost you considerably more up front – about $30 for 4 AA batteries along with the necessary charger. This compares with $4 or so for 4 disposable batteries. But you will be able to recharge your batteries about $100 times. So, you’ll end up saving a good $300 in the long haul.
You’ll have to remember to probably have a set of spare rechargables around since your batteries won’t last as long as disposables. But again, you will end up saving yourself a lot of money.
Also, with rechargables, you are not throwing away batteries and packaging constantly, so you are going to help the environment by going rechargeable.
