You may think a battery is a battery, but oh Lordy! would you be wrong. Most batteries suffer from a host of fatal flaws: they’re single use, too often unreliable, and frequently inhabited by evil spirits, just to name a few. Eneloop, on the other hand, has fully cracked the battery code. These are the Cadillacs of the rechargeable battery world. The standard Eneloop is a badass little powerpack in its own right, but the Eneloop Pro is where the real party is at, offering a high capacity battery that can be recharged up to 2,100 times. Now that’s a sweet little hot dog.
