#NI ZN RECHARGEABLE AA BATTERIES PORTABLE#

Over time, a battery's internal chemicals begin to degrade and interaction diminishes.

Ions (positively charged) and electrons (negatively charged) flow through the electrolyte, exit via the negative terminal and enable your device to function. When you put a battery in a device, like a headlamp, the electrolyte, cathode and anode interact and a chemical reaction (basically oxidation) occurs. All batteries also have some type of electrolyte-a substance that conducts electricity (a flow of electrons) between the battery’s terminals. With a basic understanding of how batteries work and what’s inside them, you can make more informed decisions about the right type of batteries for your needs.īattery basics: Common batteries, such as AAA, AA, C and D, have positive and negative terminals and two internal layers called electrodes that include a cathode (which transports a positive charge) and an anode (to carry a negative charge). Once you’ve settled on the battery size and decided between single-use and rechargeable, you may find it helpful to understand a bit more about the different types of batteries.

More expensive upfront cost than single-use batteries.

They offer better long-term value than single-use batteries (the more you use them, the cheaper they get).

Because they’re rechargeable, they generate less waste than single-use batteries.

The two main types of rechargeable batteries are nickel-metal hydride and lithium-ion. Rechargeable Batteries: These batteries are built to be recharged over and over again, in some cases up to 500 times or more.

Require disposal after fully discharged.

Very low self-discharge rate (power loss when not in use) for a long shelf life.

Cheaper upfront cost than rechargeable batteries.

The two main types of single-use batteries are alkaline and lithium. When they run out of juice, you need to dispose of them (to find battery recycling options near you, visit ). Single-use batteries: These are what they sound like. Both have advantages and disadvantages Here’s a quick look at those: If you’re shopping for common cylindrical batteries, like AAA, AA, C or D, you have the option of buying single-use batteries or rechargeable batteries (coin-cell batteries, like CR2032, are single-use only). For instance, with a CR2032 battery, the C stands for lithium, the R specifies that the battery is round, and 2032 means that the battery is 20mm in diameter by 3.2mm high. The four numbers describe the size, with the first two indicating diameter and the second two indicating height. The first letter indicates the chemical composition, while the second indicates the shape. These batteries typically include two letters followed by four numbers. Sizing for coin cell batteries (also called button cell batteries) works a little differently. AA, AAA), the more times it’s used, the smaller the battery (eg. When you see a letter used more than once (eg.

Basically, the farther you get through the alphabet, the larger the battery (e.g. You’re probably familiar with AAA, AA, C and D batteries.

If you want to know a little more about battery sizes, here’s a quick primer: If you don’t already have batteries installed, look on the device for some indication or check the instruction manual. if there are AAA batteries in there, then that’s what size you need to buy). Figuring it out can be as easy as looking at the batteries currently in your device and replacing them with the same size (i.e. You don’t need to know much about batteries to get the right size for your device.

If you’re interested in portable solar chargers and rechargeable battery packs, see our article, Solar Chargers and Portable Power. Get the right type of battery:Understanding how batteries work and knowing how alkaline differs from lithium and NiMH from lithium-ion will help you pick the best battery for your application.įor a quick reference, see our printable PDF.Decide between single-use or rechargeable batteries:Single-use batteries are cheaper upfront and have an excellent shelf life, but rechargeables can be used again and again, making them ultimately the more cost-effective choice.You can look on the device itself for an indication of what battery size it takes, or consult the instruction manual. If your gadget runs on AAA batteries, then that’s what you need.

Figure out what size batteries you need: This is simple.
