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.
