How Do You Use NiCd Rechargeable AA Batteries?
Youre working on a home improvement project when your power tool dies, but all of your disposable batteries are empty. Having rechargeable batteries on hand means you always have a backup of reliable, full-strength power. There are varied types of rechargeable batteries that have unique properties, making some more appropriate than others for particular uses, with NiCd (or nickel cadmium) rechargeable batteries being one option to consider.
What makes NiCd batteries unique?
NiCd batteries are not new technology, but they remain in use due to the numerous benefits that they offer.
- These batteries can deliver very high currents and can be recharged quickly. Low internal resistance helps to regulate temperature and also gives NiCd AA batteries the ability to provide and accept power. Its wise to note that battery chargers that charge very quickly may reduce the lifespan of these batteries somewhat.
- NiCd AA batteries can deliver their full power potential until they are dead. They benefit from being completely discharged before being charged, and lithium, NiMH, and other types tend to initially deliver high power and then steadily less power until they die.
- The amperage output of NiCd batteries is high and is at a higher voltage when compared with alkaline alternatives. You can store NiCD batteries in any state of charge without damage, and they hold their charge when properly maintained.
Which applications are NiCd rechargeable batteries appropriate for?
The ability to quickly charge and supply full power until death makes this type of battery work well in certain situations
- Cordless power tools are one use for NiCd batteries, as they require the power source to supply full power throughout the duration of the tool being used. Li-ion and alkaline batteries tend to have a drop in power output as they drain, and the rapid charging ability of NiCd batteries makes swapping out and recharging batteries convenient as you work. Many of these tools take AA-sized batteries.
- NiCd battery technology has been used for satellites, medical equipment, radios, and cameras since the 1980s, in addition to other uses since its invention in 1899. For instance, the airline industry today still uses NiCD technology in abundance.
- Applications that require consistent replacement of non-rechargeable batteries may benefit from rechargeable replacements. NiCd is produced with highly available and inexpensive materials, so these batteries require less expenditure when compared to disposables.
Why choose NiCD rechargeable batteries?
A rechargeable battery of any type offers advantages over disposable options, and these advantages are important to consumers who are both environmentally and financially conscious.
- These batteries ability to be recharged with a battery charger reduces the waste that they create. Batteries sent to landfills can release toxic chemicals as they age and become damaged. Conversely, many rechargeable batteries are recyclable.
- Since these batteries are often used in power tools and applications that require full power output, rotating batteries from a charger to use can keep a power supply always available. Additionally, theres typically no need to purchase more batteries beyond your initial investment.
