Finding a battery charger online is easy as long as you know what to look for. And that’s the thing about shopping online: it’s so easy to do a little research and quickly discover which products performed the best for others, as well as learn more about the various advantages and disadvantages of particular items.
I love rechargeable batteries. My family goes through so many batteries for the CD player, the digital media player, flashlights and more that I’m sure we’d spend at least three times as much if we used disposable batteries instead.
What about the different types of rechargeable batteries? The main thing is simply to make sure you get a battery charger that will charge the type of rechargeable batteries that you end up purchasing. That said, let’s go over some of the types of rechargeable batteries.
Two of the most popular type of rechargeable batteries are nickel-cadmium batteries and nickel metal hydride batteries. If you go to your local store to find rechargeable batteries you will see mostly these two types of batteries.
Some people say that the metal hydride batteries seem to charge faster and last longer. It seems to me that this may be true, but I can’t say that I’ve performed any strict scientific studies with which to verify these claims.
The nickel cadmium battery is slowly being replaced by the nickel metal hydride variety. Since the general consensus is that the metal hydride is the more technologically advanced battery it stands to reason that it’s likely to perform better in various areas, from charging speed to output life.
Besides using rechargeable batteries, there is also the option to choose mechanistic devise where possible. For example, a clock that must be wound periodically does not use any type of electricity, from a battery or the wall circuit.
After all, when we charge our batteries the power comes from somewhere. So, a truly sustainable solution for our powered devices would side step the battery issue altogether. But until then, the rechargeable battery is certainly an important step.
