Best Batteries of 2018

When it comes to finding the perfect battery, the search can feel overwhelming. There are so many different types of batteries and brands out there, how will you ever know which are the best batteries for you?

We got you with this comprehensive guide on batteries, so you'll never again waste money on a bad battery.

Batteries by Type

The most common size batteries for consumers are AA and AAA sizes. The only problem, is there are so many different types of AA and AAA batteries, how do you know which is the best one? Here are the most common types on the market.

Lithium

Lithium AA batteries are usually the highest rated in terms of performance. The only problem is that high performance comes at a high price. This is because these batteries will last longer and are mainly suggested for gadgets.

Alkaline

Alkaline batteries have been around for centuries because they're inexpensive and effective. You'll find these kinds of batteries in an array of electronics from cameras and flashlights to even music players. Alkaline batteries have a standard 1.5-volt output that will remain consistent until the battery loses its energy.

There are a few downsides, like most alkaline batteries can only be used in low drain devices like toys, wall clocks, and remote controls. Another issue is these batteries have been known to release of leak battery acid. These leaks are actually not hazardous, they're just annoying to clean and can sometimes stain electronics and hardware. 

Zinc-carbon

This type of battery dates back to the 1800s and formed the foundation for most household batteries. Similar to the alkaline battery, zinc-carbon batteries also have a long shelf life, are cheap and work well in gadgets and toys. But Alkaline batteries do last longer than zinc-carbon types.

How a Battery Works

You might be interested to know why and how batteries generate usable electricity. Turns out the AA battery actually doesn't have strong electricity. The battery actually generates its own electricity by taking stored chemical energy and changing them into electrical currents.

AA batteries are made up of two terminals and an electrolyte. The two terminals are the positive and negative sides, while the electrolyte is the center that connects these two ends which are also referred to as a chemical medium.

Electricity is generated by the chemical energy filled in the battery which then creates a circuit. This chemical process leads to accumulation of electrons that transfer from the battery and flow through the gadget that's trying to be powered.

Safe Battery Storage and Disposal

If you want your batteries to last, the most important action you can take is making sure you store your batteries properly. Batteries should be stored at about 60 degrees Fahrenheit, in a completely dry area that has no exposure to sunlight.

Some people think that batteries need to be stored in a refrigerator or freezer, but that is actually wrong. Actually, storing your batteries in the fridge can really damage your batteries as the condensation from the fridge creates corrosion.

Rechargeable batteries should be stored when they're at half power to make sure they never fully drain. A fully drained battery is difficult to recharge. If you're using alkaline batteries you can use them until they run out, but be sure to throw them out after. 

Most alkaline batteries can be disposed of in your garbage since they don't currently contain any toxic chemicals like mercury. You just want to be sure that you're not disposing large amounts of alkaline batteries at once because this can cause heat or a fire hazard.

Lithium and rechargeable batteries need to be disposed of differently and need to be taken to a recycling facility. Make sure you follow any laws in the place of disposal and follow them. If you throw away these batteries with the rest of your trash there's a good chance the toxic chemicals from the batteries can get into the ground, water and atmosphere.

How to Choose Batteries

When choosing your batteries, be sure to keep in mind four main factors. The length of the batteries shelf life, the batteries performance, price and how friendly it is to the environment. Most batteries do not check all these boxes, but manufacturers are working towards this.

Here are some other features you want to look for when choosing your batteries,

Milliamperehours (mAh) and Claimed Capacity mAh

These are both ratings that measure battery capacity. If you're looking for a battery that will last longer, then find one with a higher mAh. Claimed capacity mAh is important for high drain devices such as digital cameras.

Leak Protection

Fluid can leak out of poorly designed batteries which can damage your device. The leak of battery acid is also a human health hazard as it can burn your skin or eyes. So make sure you find batteries that have a good durable design with leak protection.

Temperature range

You want to make sure your batteries won't die in extreme temperatures. The best AA disposable batteries will last in temperatures from negative 40 to 140 degrees.

Weight

Lightweight batteries are very handy, especially for powering a camera or anything else you need to carry around on the go a lot. You're not going to want a heavy battery to power any portable devices

Voltage

Lithium batteries tend to have higher voltage their alkaline batteries. Just be sure to see if the device you need to power needs high or low voltage. One isn't better it's just what is right for your device.

AmazonBasics AA 48-Pack

You may be surprised to find out that Amazon makes their own batteries, and they actually can hold their own when compared to major battery brands. AmazonBasics AA is reasonably priced (they cost much less than name brands) but they still deliver a great performance. The packaging of these batteries is a cardboard box that you can easily reuse.

These batteries have a 10-year shelf life, so you have an entire decade to go through this 48 pack. You can use AmazonBasics on both high and low devices, as they are all-purpose and can be used on just about everything.

The only downside is despite its great performance, AmazonBasic is still less powerful than Energizer batteries, that stay true to their ad campaign and keep going and going. Another issue is like other alkaline batteries, sometimes AmazonBasic leak if you leave them in a device for too long.
