What’s the worst part about using rechargeable batteries? Well, most likely it’s that inevitable date when the battery loses any ability to hold a charge. In 2005 Sanyo unveiled the Eneloop battery which revolutionized the capabilities of the rechargeable battery. Now, Sanyo is back with the new and improved Eneloop 1500 – a far more innovative and longer lasting battery than its predecessor.

So, what actually makes this new Eneloop so amazing? Let’s look at the difference in charging cycles between the two batteries.

Where the older model could be recharged an impressive 1000 times, the new Eneloop is rechargeable up to a whopping 1500 times. This amazing new model also has an improved self-discharge, enabling the batteries to retain 75% of their capacity after being stored for up to 3 years, whereas the earlier model retained 85% after only 1 year.

The new Eneloop can be depended on to function in temperatures as low as -20°C. On top of their already eco-friendly design, Eneloop batteries come pre-charged by solar energy in Japan. These Earth-friendly super batteries can be found in either AA (Mignon-eneloop) or AAA (Micro-eneloop) sizes at amazon.com
