This battery shell optimizes the balance of the components and when combined with the improved alloy material and conductive surface layer of the positive electrode active material enables the new eneloop pro cells to be recharged up to 500 times. While eneloop has a slightly lower voltage than equivalent dry batteries, it works better in almost any device where standard batteries are used. It reduces the chance of unexpected battery failure in the field, giving peace of mind to professional users.

Like the original they’re based on reinvented NiMH (Nickel Metal Hydride) technology, designed to have neither a memory effect nor to discharge significantly over time when unused. In our tests, we found that we could get around 170 full-power flashes from a set of alkaline batteries, with a steady slowdown in recycle speed.Use with the confidence that comes from products made to the highest standards of Japanese craftsmanship. Your eneloop pro batteries maintain excellent discharge performance even when used in heat and cold.

While eneloop pro batteries were designed to provide more power for high drain devices they will also perform well in conventional devices that require AA or AAA batteries. Made in Japan these Panasonic Eneloop Pro AA batteries are the ideal choice for powering high drain devices such as digital cameras, flashguns or photo strobe flash lights.These Panasonic Eneloop Pro AA batteries have been developed by Panasonic and are pre-charged NiMH energy units that have a high capacity. eneloop and eneloop pro batteries deliver exceptional performance at extreme low temperatures, down to –4 degree Fahrenheit. We've improved the metal-hydride alloy lattice inside your eneloop pro battery so that it retains 85%* capacity even after one year in storage. There are two electrodes inside each cell; one is made of Zinc, known as the anode (the negative terminal) and the other is made of Manganese Dioxide, known as the cathode (the positive terminal). Hence, this Panasonic Eneloop vs Eneloop Pro comparison will help you get a clear picture, and help you decide between the two.
