It should be done every few months to prevent the batteries from losing their full charge capacity. A discharge cycle occurs when the battery is fully drained and then charged to full power again. When choosing a charger, be sure it has a button that allows you to easily run a discharge cycle. This may be inconvenient if you only need a single battery for a smaller device, so consider a charger that allows you to recharge the batteries one at a time. Some chargers require you to charge the batteries in groups of two, four, six, or eight. NiZn and Li-Ion batteries require specialized chargers, but NiMH and NiCd batteries can be used with universal chargers. Others are sold separately, so you must purchase the charger on your own. Some rechargeable batteries are sold as sets that include a charger. We offer the following general guidelines.Ĭhoose AAA batteries with capacities between at least 6mAh.Ĭhoose AA batteries with capacities between at least 12mAh.Ĭhoose C batteries with capacities between at least 25mAh.Ĭhoose D batteries with capacities between at least 50mAh. The mAH ratings for rechargeable batteries varies. However, batteries with lower mAh ratings take less time to recharge. An 1800mAh battery will last three times as long as a 600mAh battery, for example. The higher the battery rating, the longer the battery will last per charge. The amount of energy a rechargeable battery can store is measured in milli-ampere hours, or mAh.

Rechargeable batteries are available in a variety of sizes to accommodate most devices and appliances, including the following.

Lowest capacity among rechargeable batteriesĬontain toxic substance, so must be disposed of at special recycling centers They also contain a toxic metal, cadmium, which is a concern for many people.

NiCad batteries were the first rechargeable batteries to hit the market, but they are a poorly performing option these days. May destroy devices that call for low-voltage batteriesĪren’t available in standard sizes, including AAA, AA, C, and D These batteries work well with some specialty items, such as flashlights. Li-Ion batteries are a high-voltage rechargeable option. Tend to lose charge quickly if used often Provide higher voltage that can make flashlights brighterĬan last longer in some items than NiMH batteriesĬan discharge more quickly than other options due to high voltageĬan self-discharge if left unused for more than a month May self-discharge if left unused for more than a monthĪn effective alternative to NiMH batteries, NiZn rechargeable batteries are another high-performing option. Larger capacity than other types of rechargeable batteriesĭon’t work as well in devices that require more than four batteries NiMH rechargeable batteries are a high-performing option that is easy to find at most stores. When you shop for rechargeable batteries, you’ll find that there isn’t just one “type.” Below, we delve into four of the main types of rechargeable batteries from which to choose. This is particularly true for devices that require significant power.īestReviews Types of rechargeable batteries High-quality rechargeable batteries often last longer on a charge than single-use batteries. Rechargeable batteries are long-lasting.And because they can be used repeatedly, rechargeable batteries require fewer natural resources to produce than single-use batteries. They are an eco-friendly alternative that you can feel good about using because they don’t contain environmentally hazardous chemicals or metals. Rechargeable batteries are environmentally friendly. And with a little forethought, you can arrange it so that you always have a set charged and ready to go. You don’t have to run out and buy new batteries every time your alkalines burn out. You’ll quickly earn back your investment when you buy rechargeable batteries. Why? Because you can use them hundreds, if not thousands, of times. While it’s true that rechargeable batteries cost more upfront, you save money in the long run. Here are a few reasons why you might want to make the change. Perhaps you haven’t made “the switch” from traditional alkaline batteries to rechargeables yet. Rechargeable batteries use nearly 23 times fewer non-renewable natural resources than single-use batteries.
