While most AAA rechargeable batteries have an mAh capacity, these have a whopping 1,mAh capacity, meaning they last longer between charges and are an ideal choice for electronics that draw a lot of power. Their larger capacity also means they typically take longer to charge than mAh AAA batteries. These are high-capacity, 2,mAh batteries that last longer between charges and can be recharged up to 1, times. Our favorite rechargeable batteries are the Energizer Recharge Universal view at Amazon , a solid value with a five-year lifecycle that are made partially from recycled batteries.
Typically, AA and AAA batteries come in one of two flavors: lithium or alkaline though please don't lick your batteries. Lithium batteries are longer-lasting, less prone to leakage, and more expensive. Alkaline batteries are cheaper, more ubiquitous, but rarely rechargeable. The total lifespan of your batteries, as well as the duration of a single charge for rechargeable batteries, depends on a number of factors: the draw of the device they're inserted in, voltage, the total time they're in active use vs.
Generally, lithium and eneloop batteries will last longer than their alkaline alternatives, both in terms of individual charge and total life span. To avoid ruptures, be sure you're not inserting batteries in the wrong direction, especially for long periods of time, and store your batteries or the devices they're living in away from heat sources and in dry conditions to avoid corrosion and deteriorating the case, as well as the battery cavity of the device itself.
The life of a rechargeable battery is defined by how many times you can charge it, use it, and charge it again before it no longer works. Look for rechargeable AA and AAA batteries that are rated for at least recharge cycles, or up to 2, recharge cycles for higher-end batteries. If your devices use a lot of power, then high-charge capacity is essential. This is extremely important if you want to keep a bunch of extra AA and AAA rechargeable batteries in your drawer and grab fresh ones when you need them instead of waiting for the charger.

An AAA battery is a single cell that measures The positive terminal has a maximum diameter of 3.
AAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type.
AA batteries have about three times the capacity of AAA batteries. With the increasing efficiency and miniaturization of modern electronics, many devices that previously were designed for AA batteries remote controls, cordless computer mice and keyboards, etc. From Wikipedia, the free encyclopedia.
