Energy at your fingertips: alkaline and rechargeable batteries

Added: Wednesday, 9/13/2023


You probably don't even realize how many batteries and accumulators you use every day. They are necessary in every electrical device without permanent mains power, such as watches, cameras, night lamps, children's toys and bathroom water heaters. In some cases, choosing the right battery may be more difficult than usual. How to find the right model, read the markings and when should you choose rechargeable batteries instead of alkaline batteries?

What markings do the batteries have?

KODAK Ultra Premium AA-4 LR6 alkaline battery 4 pcs. Battery markings help you find the right model if you can read them. They consist of three parts - two capital letters and a numerical designation.

The first letter in the marking refers to the battery technology and its chemical system. It is worth knowing that not every battery has this marking. If it is made using the most basic technology and has a zinc-carbon cell, only one letter will appear before the numbers. If the marking has two letters, the first one indicates the type of cell the battery is made of.

The most common designations for alkaline batteries are:

  • A – zinc-air cell;
  • C – lithium-manganese cell;
  • L – alkaline cell,
  • P – zinc-air cell;
  • S – silver link;

The second letter of the battery designation (the first in the case of a zinc-carbon cell with a shorter designation) refers to the shape of the battery. Only three letters are used here:

  • R for cylindrical batteries - this group includes the popular AA batteries and AAA batteries ;
  • F for flat plate batteries;
  • S for rectangular and cuboid batteries.

The last part of the battery markings are numbers that represent the catalog number of a given model . Interestingly, in many cases these numbers are not randomly selected. In some models, they refer to the dimensions of a given battery, although not in every case with the same precision. For example, popular AA batteries called finger batteries are marked as R14505, and their dimensions are exactly 14.5 mm in diameter and 50.5 mm in height.

What capacity should a good battery have?

Kodak MAX AAA alkaline batteries 10 pcs. Battery capacity is often not provided by manufacturers. It is difficult to measure it precisely, and the obtained result always depends on the measurement conditions. On the other hand, battery energy consumption is not constant and depends primarily on the device. For these reasons, battery capacity given in mAh are approximate ranges rather than exact values.

So how to find good and high-capacity batteries? Pay attention to their chemical system, because this is where the capacity depends the most.

  • Lithium batteries , considered to be the most capacious, hold approximately 3000 mAh .
  • Alkaline batteries , one of the most popular, have a capacity between 2000 and 2500 mAh .
  • For comparison, basic zinc-carbon batteries are between 400 and 1000 mAh .

If you are looking for high-capacity batteries for devices with high energy consumption, consider rechargeable batteries. AAA and AA batteries can have a higher capacity than a similar model of alkaline batteries by up to over 1000 mAh! Moreover, in their case the capacity is measured much more precisely than in disposable, non-rechargeable batteries.

When is it worth choosing rechargeable batteries?

In use, rechargeable batteries do not differ from classic alkaline batteries. The only difference is their repeated use. The battery charger replenishes the energy reserves in the rechargeable batteries, so they are ready for further use after a few hours. Rechargeable batteries are slightly more expensive than alkaline batteries, but they have a much longer lifespan and can quickly return the investment.

Kodak AA KAAHRP-4 2100 mAh rechargeable batteries Remember that not every device will have rechargeable batteries as the best choice. They are recommended primarily for frequently used devices with high power consumption . Using rechargeable batteries in equipment such as a wall clock, which uses very little energy, will not result in visible savings. It is therefore recommended to use rechargeable batteries when the alkaline batteries in a given device need to be replaced after about 2 months.

Rechargeable batteries also have a limited lifespan, and their occasional use will not extend it at all. They usually perform well for 5 to 10 years from their date of manufacture. Take full advantage of their capabilities in devices that require frequent battery changes.
