The invention of the battery changed the way we use technology. It allowed us to get rid of the power cord and take our gadgets wherever we want. Think about how less useful your smartphone or tablet would be if you had to plug it in whenever you wanted to use it.

With the gift giving season right around the corner, we thought we'd take a look at some batteries you might need and tell you which ones are the best performing. There are all kinds of brands from Duracell to Kirkland and even Amazon is selling their own branded batteries.

AA Batteries

First, let's look at the most common disposable AA battery types.

Alkaline

Alkaline batteries became a popular replacement for zinc-carbon batteries in the 1970s. The alkaline battery was built to last two to 11 times longer than older batteries.

  • Positives - One great feature of alkaline batteries is they have a really long shelf life. They can sit around between five and 10 years and still have plenty of energy. They are also relatively inexpensive.
  • Negatives - Some downsides to alkaline batteries are they are prone to leaking and they're not great for high-drain devices. If the battery leaks while in use, it could damage your gadget.

Standard alkaline batteries do not work well in high-drain devices like digital cameras. The reason is they are not capable of pumping juice out fast enough.

There are special high-drain versions of alkaline batteries but your best bet, and most cost-effective choice, is to use a rechargeable battery for high-draining devices.

Lithium

Next, we'll take a look at lithium batteries.

  • Positives - Lithium batteries are great for high-drain devices. They are also really lightweight, weighing about one-third of alkaline batteries. Lithium batteries work really well in smoke detectors because they will last up to seven years in use. They have a shelf life of between 10 and 15 years.
  • Negatives - Lithium batteries are more expensive than alkaline batteries. Also, it's very rare but lithium batteries have a small possibility of exploding.

Lithium batteries are very lightweight. They are also great for cold weather conditions and are rated for lower temperatures than any other type of battery.

Plus, when stored at cool temperatures, lithium batteries can retain about 90 percent of their charge for nearly 15 years.

Zinc-carbon

Finally, we will look at zinc-carbon batteries.

  • Positives - Zinc-carbon batteries have a long shelf life. They are also very inexpensive and are good for low-drain devices like remote controls and clocks.
  • Negatives - Zinc-carbon batteries have the lowest capacity of any of the disposables.

Zinc-carbon batteries date back to the 1800s and it's the original chemistry for household batteries. Alkaline batteries have pretty much replaced zinc-carbon batteries in use these days because they last up to 11 times longer.
