While modern gadgets have become increasingly sophisticated, swapping or charging out their batteries is still a necessity. But the wide range of batteries available, actually makes it difficult to know which to choose for which device.

Since not all batteries perform as promised (not even those from famous brands), before you buy batteries online or offline, it is important that you learn about the types that are available as well as which ones offer the best value for the money.

Types of Batteries

Whether shopping for batteries online or offline, know there are different models, performance and price wise. However, because AA batteries are the most popular ones used for household items such as garage door openers, portable clocks, calculators, etc., we will focus on them.

Most types of AA batteries come in disposable and rechargeable forms. As you may know, rechargeable batteries are healthier for the environment. However, eventually you will need to replace them when they no longer charge. Rechargeable batteries, on the other hand, have a shorter lifespan but are considered by many as a more convenient solution over rechargeable types.

  • Nickel-Metal Hydride AA Batteries, also known as NiMH, are made from metal hybrid and nickel. They fit in most devices that require an AA battery and offer good performance. The downside with these batteries, is that they have the shortest shelf life and shortest length of use.
  • Alkaline AA Batteries are the most popular and most affordable of all. They are available in name brand and in generic form as well. They are one of the batteries with the shortest life shelf and tend to drain very quickly. Due to that, they are mostly recommended for lower power devices, such as small toys and television remotes.
  • Lithium AA Batteries are the most powerful batteries you can find, but you have to be careful with them because they can be extremely toxic. They are recommended for long-term, low-level use as they do not leak as much as other batteries.
  • Carbon Zinc Zinc Chloride AA Batteries are heavy duty devices meant for repeated extended use. They are commonly found in kid’s toys that require a large amount of power for an extended period of time.

Tips to Help Your Batteries Last Longer

  • Store your batteries in a cool, dry place.
  • Before putting new batteries into a device, clean the battery compartment and the contact surface by rubbing them with a rough cloth.
  • Take the batteries out if you don’t plan to use a device for a few months.
  • If the device needs more than one battery, always use batteries of the same brand, type and age.
  • Empty batteries should be disposed as soon as possible and kept out of reach of children.
  • Never try to recharge non-rechargeable batteries because they can explode.
