'Triple A" batteries are one of the most common power sources for all sorts of portable electronic devices and businesses and households everywhere spend hundreds of pounds over time, replacing batteries in those devices. Until recently, there wasn't an ideal rechargeable alternative, because most NiMH batteries, while much more efficient than NiCd cells, don’t retain their charge well when stored unused. Fortunately, engineers like those at Panasonic have developed new technologies like Eneloop, which surmounts this obstacle. This third-generation Eneloop design greatly extends the number of charging cycles their batteries withstand, as well. The bottom line for you, the consumer, is incredible savings over conventional batteries and lower environmental impact. It also means these batteries can be shipped to you pre-charged and ready to be put to use.
Eneloop batteries have been developed to produce a NiMH cell with a self-discharge rate of no more than 15% per year and only 30% over 3 years. By comparison, conventional NiMH batteries can lose as much as 2% of their stored charge per day. Since many AAA-powered devices aren't used daily, this difference isn’t just significant, it's a game-changer. What’s more, this generation lasts through as many as 1800 charge/discharge cycles, which means they'll last for years before you'll need to replace them. That's almost twice the number of charges for first-generation Eneloop batteries and 300 more than second-generation. Memory effects have also been effectively cancelled out, so you can charge these at any level without losing performance.
Don't keep throwing your hard-earned pounds away on conventional, disposable batteries or less-efficient NiCd or alkaline rechargeables. Not only are these batteries far superior, they're recyclable and charged using solar energy, so using them means reducing your carbon footprint in a big way. What could be better than saving the planet while saving yourself money?
