Understanding Sanyo NiCd Rechargeable Batteries
Since their introduction in the latter part of the 20th century, rechargeable batteries have been widely adopted for several different consumer electronic uses. Sanyo NiCd units offer a variety of uses within photographic equipment, handheld power tools, and radio-controlled cars or other toys. Understanding the sizes and features of these units can help guide your purchasing decision.
What are the different Sanyo battery sizes?Much like disposable alkaline units which are life-limited and must be thrown away after they lose their charge, NiCd units are available in sizes from AAA to D for single cells as well as 9V units that are multiple cells. Larger units built for heavy industry applications or use in automotive applications may contain hundreds of cells.
Do you need different chargers for NiCd and NiMH batteries?They are both rechargeable, but due to their chemical makeup, have different capacities as well as different discharge rates. Often, NiCd battery chargers operate on a timer system and charge the batteries for a set amount of time. Because NiMH units have a greater capacity than NiCd batteries, using a NiCd charger that turns off after a set amount of time may leave your NiMH units undercharged. To optimize performance and charging, it is wise to use a charger designed specifically for your Sanyo units.
What are some features of Sanyo NiCd batteries?These batteries offer several benefits in electronic applications including:
- Numerous charges: The ability to charge these units multiple times with a full lifespan of up to 20 years.
- Temperature compatibility: Functionality in extreme temperature conditions, performing well in temperatures that range from -40 degrees to 70 degrees Celsius.
- Light up on the fly: Good for emergency lighting due to lifespan and temperature thresholds.
NiCd units contain cadmium, a heavy metal element that is an environmental hazard. Most states have regulations and rules governing how these units should be handled once they have reached their lifespan limits, and most states offer battery recycling programs at various retailers and commercial operations in order to safely handle them.
How do you store rechargeable batteries?When not in regular use, storing them requires that you discharge the majority of the charge in the cell until it is at 40% or less. Store these units in a cool, dry location, at temperatures from -20 degrees Celsius to 45 degrees Celsius.
