Value-Added Battery Information
If you’re new to rechargeable batteries jargon and usage, you’ll find some valuable pointers here to factor in to your purchasing decisions.
The 2 most commonly used rechargeable battery chemistries today are: NiMH (Nickel Metal Hydride) and NiCD (Nickel Cadmium). The working voltage on both of these battery chemistries is 1.2 Volt (with the exception of the 9 Volt NiMH or NICd. Alkaline batteries (non-rechargeable) are a 1.5 Volts.
The most common battery sizes are: AA, AAA, C, D and 9 Volt. Both NiMH and NiCD batteries will work in any consumer product that can use Alkaline batteries of the same size.
Rechargeable batteries are rated by the milliampere hours of power they deliver. The mAh represents the capacity of the battery. Therefore, the higher the mAh rating, the longer the battery will last once it is fully charged. ie: A rechargeable battery that is rated at 2000 mAh, will power your device twice as long as a battery that’s rated at 1000 mAh. You will find that higher mAh rated batteries are usually more expensive, but this is not an indicator that they’re better batteries, rather only that they’ll run your product for a longer period of time.
NiMH chemistry is a newer technology than NiCD chemistry and has become the more popular choice among consumers these days for a variety of reasons, namely the following three features:
Memory effect (also known as battery memory) happens when a NiCd battery is not fully drained of power before being recharged. If it’s recharged prior to a depleted power state, (prior to being “dead”), the recharging process only “tops off” whatever power is missing and this then, becomes the new, total capacity of the battery. You will be able to have approximately 500 FULL charge cycles on a NiCd battery, if you recharge it only when it is completely empty.
To be sure of if there’s any power remaining in your NiCd batteries before you recharge them, it’s best to own a Battery Tester. This inexpensive and handy gadget will prove to be invaluable to you, in determining when your batteries are truly depleted. In this way, you will not subject your NiCd’s to memory effect and will benefit from the full power of each life cycle that the manufacturer intended. And if this is your first time shopping for NiCd batteries, let us point you to a good quality Battery Charger.
However, no memory effect issues exist in NIMH chemistry. A nickel metal hydride rechargeable battery does not have to be empty before being recharged. Many people appreciate this worry-free
aspect to their battery maintenance.
NiMH batteries have a much higher mAh rating then NiCD Batteries. This assures longer run time. People can go for longer excursions with their families, let’s say, without stockpiling extra batteries with them. The higher capacity, higher mAh ratings of NiMH promise longer power before they have to be changed or recharged. Of course, they cost more than NiCDs but it is justified by many as worthwhile for this longer service.
You can charge and recharge an NiMH rechargeable battery almost twice as many times as a NiCD battery. We recommend getting NiMH batteries for high drainage devices such as Digital Cameras, Flashes, Radios and Flash Lights, whereas NiCD batteries are ideal for Solar lights, Clocks, Remote Controls and other low-drain devices.
It is important to know (and surprisingly, many people do not know this!) that rechargeable batteries are sold with very little to no charge at all. They must be charged before their initial use and once the battery is charged, they begin to lose (self-discharge) approximately 2% - 3% of their capacity per day, when not in use. Therefore after roughly a month's time, most rechargeable batteries will need to be re-charged.
The good news is that there is a battery technology called low-discharge (also called Low Self-Discharge). This battery which also comes in all the sizes mentioned above will be delivered to you fully charged, and only lose 15% of their capacities (when not in use) over an entire year.
We're pleased to provide an impressive inventory (ALWAYS FRESH, GUARANTEED!) of Low-Discharge rechargeable batteries within our product mix.
