A Buyers Guide In Buying Batteries

Batteries are these small compact things that power the devices that you are carrying right now in order for you to wirelessly use it. Remote control, watches, flashlights, car keys, toys, your old walkman, your old boom box and many many more. There are various types of batteries for various needs. Even if the batteries are old school there hasn’t been anything at all that can replace it. But there are certain changes to it but mostly internal.

So the good news is if your old RC toy plane still is in perfect condition, you can still use it today. But the thing is it’s actually more complicated than that because there are various types of batteries and not to mention you still need to consider its size, chemistry, capacity, voltage, and polarity. Yeah yeah, you might be thinking that it’s really hard to consider the things mentioned above in buying just a simple battery but if you do have the time it will help to know just a bit of it. So if you’re wondering how you will be able to properly buy a battery below are some of the key things that you should know.

Types of batteries: There are basically 5 types of batteries. This is where you start in identifying the right battery for your device and just by looking at a battery you would already know where it will belong. Below, you will find the 5 types of batteries:

  • Button/Coin Cell Batteries – Silver Oxide, Alkaline, Zinc Air and Mercury Batteries
  • Cylindrical Batteries
  • Lithium Non-Rechargeable 3V Button/Coin Cell Batteries
  • Cylindrical Lithium Batteries
  • Rectangular Batteries

The battery equivalents: Battery equivalents are basically a chart that has the list of all old batteries and their corresponding newer replacement. This can be a good buying guide for any battery user in order to know the best battery for their device. below is the battery chart for your reference:
