Battery comparison 2018: battery

Batteries - the omnipresent source of many useful household and recreational items. Whether the clock in the living room, the remote control for the home theater or the remote-controlled car of your child: anywhere the battery performs inconspicuously and reliably their service. As our environment becomes ever more sophisticated, it's no wonder that batteries are becoming increasingly important, Accordingly, the turnover of the battery industry has almost doubled since 2009 (Source: Federal Statistical Office).

We have dealt with a very common battery type and performed our AA battery comparison 2018. Here you will find a compact and clear purchase advice that will help you to determine your own AA battery test winner.

1. The right battery: Save yourself the constant change

What does AA mean for batteries?

The letters indicate the size of batteries. A Mignon AA battery is typically silo-shaped, so long and round. In terms of shape, it is identical to the AAA batteries, with the AAA batteries being the smaller and slightly smaller version.

Batteries come in a wide variety of sizes and shapes, and there are many manufacturers and brands that make it hard to find the best battery. In our battery comparison, we focus on the AA battery, also known as the Mignon battery.

If you buy a battery, you want to repeat this process as rarely as possible. Nothing is more annoying in view of the small energy storage than to have to make the next one shortly after the last battery change.

So it's all about great capacity and performance, Here are many batteries on a comparable, but not always at an identical level, so it is worthwhile to look closely at the battery purchase. The initial cost per battery is relatively low, but you can With the right choice in the long term costs and avoid the annoyance of frequent battery change.

Also rechargeable batteries is available in AA format, Be it the NiMH, Nicd or lithium battery: All versions of the rechargeable batteries can also be found in the form of an AA battery. For environmentally conscious buyers, there is often no way around a battery shop over, but the battery is always a good battery charger, which must be purchased in addition.

Also note that rechargeable batteries do not produce the same voltage as single-use products. Therefore, it is recommended, for example, to operate good cameras rather with disposable battery types.

We have summarized the advantages and disadvantages of the disposable battery over the batteries for a better overview:

  • higher voltage - more flexible in different devices
  • Performance losses during storage are not so high
  • Purchase costs for a charger in the amount of up to 50 € omitted
  • lower acquisition costs
  • Uneconomic: not reusable and very harmful to the environment if not disposed of properly
  • with frequent use ultimately more expensive than rechargeable batteries and charger

2. Which battery types are there? From the remote control to the smoke detector

To give you a compact overview of the different battery categories, we have listed some of the most common types and their main uses.

Smaller electronic devices that require less power, for example:

  • Measuring device
  • transistor radios
  • smoke detector

The trend is for the little one: Newly developed devices often require less energy than their predecessors. So it is that the areas of application of the battery types are increasingly mixed and partially postponed. For example, the baby battery's mignon battery is increasingly competing, while the baby battery, in turn, is contesting earlier uses for the larger and heavier mono battery.

3. Purchase criteria for AA batteries: You must pay attention to this

3.1. capacity

Battery comparison 2018: batteries

The Energizer Ultimate lithium batteries with 3,000 mAh.

One of the most important criteria is the capacity of the AA battery. A capacity of about 2,000 mAh (milliampere hours) should at least have your AA battery of our recommendation.

Many a product, such as Energizer's Ultimate Lithium Battery, has a capacity of 3,000 mAh - a peak in the AA battery class.

Make sure you pay attention to the specified capacity when buying, because not least the life of a battery is related.

High performance is not always required: Some devices are designed to work optimally with medium capacity. Batteries with around 2,000 mAh are particularly suitable for this purpose. Of course, using a stronger battery will not damage the equipment, so in such cases you are well placed even with a capacity of 2,600 mAh.

3.2. performance

The performance of a battery results from its capacity and its voltage. Mignon batteries typically have a voltage of 1.5 volts (Rechargeable AA batteries 1.2 volts). If your battery now has a capacity of 2,600 mAh (2.6 Ah), the following calculation results:

2.6 (Ah) x 1.5 (V) = 3.9 (Wh / watt hours)

Ultimately, since the voltage in the AA batteries is 1.5 volts, you can also read the capacity based on the capacity.

Battery pack of five batteries.

However, if it is a battery or battery pack, the calculation of the power is already more meaningful.

With a battery pack (for example, ten batteries in one group) with the values ​​2.600 mAh (2.6 Ah) and 1.5 V per battery, the number of batteries is now added - in our example, we assume ten batteries, the have been grouped together.

Then the following calculation results:

2.6 (Ah) x 1.5 (V) x 10 (batteries / cells) = 39 (Wh / watt hours)

3.3. discharge

Battery comparison 2018: 2018

Protect your batteries from heat during storage.

Batteries discharge over time even when not in contact with an electronic device. This self-discharge can ensure that long-term stored batteries no longer work or need to be changed much earlier.

Decisive influence on the speed of self-discharge has the temperature: The warmer it is, the faster the batteries can discharge.

Therefore, be careful not to store the batteries too warm and keep in mind the self-discharge problem when you think of buying a lot of batteries.

Rule of thumb for heat influence: With temperature increases of 10° C, a battery loses about twice as fast energy.

3.4. Manufacturer and prices

Battery comparison 2018: 2018

Varta batteries are among the best on the market.

The price of a battery also gives a little indication of the quality of your AA battery. Particularly cheap batteries, which are often sold in large battery packs, mean a slightly greater risk that some of the batteries are defective from the outset.

You can counteract this danger by orienting yourself on well-known branded products, which can also be reasonably priced (from around 15 cents per battery). We have therefore listed some proven brands that guarantee the necessary quality, For example, you can usually go wrong with Varta batteries.

  • ansmann
  • APC
  • camelion
  • Duracell
  • Energizer
  • GP
  • Grundig
  • Maxell
  • Panasonic
  • Powerone
  • Rayovac
  • Sanyo
  • Varta

4. Questions and answers about AA batteries

4.1. How much mAh does an AA battery have?

The Miliam per hour value of your desired battery should be at least 2,000, better yet 2,600, Usually the values ​​of the AA batteries are between 2,600 and 3,000 mAh.

4.2. How many volts does an AA battery have?

Common AA batteries have 1.5 volts. You will not be able to recharge them, which is why you must dispose of the batteries as soon as they are completely discharged.

Rechargeable Class AA batteries have 1.2 volts, so they are a little less voltage.

One like the other? The small differences are important!

4.3. Did the Stiftung Warentest carry out an AA battery test?

Yes, the Stiftung Warentest last made an AA batteries test in 2010 and chose the product Ultimate Lithium from the manufacturer Energizer as the battery test winner. This enabled a lithium battery to outperform all tested alkaline batteriesalthough these are commonly said to have better performance.

4.4. Which AA batteries last the longest?

The Stiftung Warentest also has an answer to this - and this is not surprising. Energizer Ultimate Lithium batteries last about twice as long as most alkaline batteries, Also in terms of self-discharge, the product of Energizer was able to convince and clearly distance the competition with the outstanding overall score of 0.9.
