In 2013 Panasonic announced a redesign of the Sanyo-branded Eneloops. In Japan, this led to the removal of the large Eneloop logo, and to be replaced with a large Panasonic logo. Right underneath the Panasonic logo is the following text printed: eneloop rechargeable battery. The product codes changed from HR-3UWX to BK-3HCC for the AA batteries and BK-4HCC for the AAA batteries. In Europe, they are called BK-3HCC E and BK-4HCC E, respectively. This is the total amount of pops the flash could make on a set of batteries. This is the average between 2 flash units.. according to Sys. Standard Eneloop batteries have two things that make them stand out over other NiMH batteries: longevity and charge retention. The Eneloop AAA batteries benefits from both. Rated to retain 70% of their charge after 10 years, these are batteries that you can charge up and stow in a cupboard in the knowledge that they’ll be ready for use when you need them. There's more to buying a battery charger than you might think. From what features you'll need to how to save money - use our expert tips to choose the best charger for you. The Eneloop PRO is excellent for Camera flashes, flashlights, etc. When you need maximum power or maximum battery life with a high-drain application, this is the battery to get. Inside camera flashes, Eneloop PRO also recycles the flash faster and can, therefore, pop more bursts in a shorter time!

Finally, the 5th generation Eneloops were produced, with a minimum capacity of 930mAh for the Eneloop PRO AAA and 2500mAh for the Eneloop PRO AA. Standard Eneloops have a longer shelf life. They only lose 30% of their charge in 10 years, while the PRO batteries lose 15% in 1 year.Eneloop PRO is excellent for longer battery life in flashlights as well. The capacity of 4 Eneloop Pro AAs is about 25% more than 4 regular AA Eneloops. This ability to retain charge also means that the Eneloop AAA are a great choice in those scenarios where the ability to hold a charge is more important than capacity. Think of low-drain uses, such as for remote controls. Then came the Eneloop XX batteries. Eneloop XX were first available to the North American and European markets. However, when they finally became available to the Japanese market, Sanyo didn't name them Eneloop XX, but Eneloop PRO. The standard Eneloops are always good to have. They are just great batteries overall with a high life expectancy, powerful, and low self-discharge.

The diameter of Pro batteries is larger than regular Eneloops and, therefore, can be a very tight fit in certain devices. So if your standard white Eneloops are a tight fit, don't get the Eneloop Pro. It's interesting to note that these batteries had never been available in Japan with that particular product code. It looks like they were only available in China. Eneloop XX batteries sold in China in 2012 had a different product code, as can be seen in this Chinese Announcement. These batteries received the product code HR-3UWXA. Although the additional letter A could have indicated a new design or product (as this was the standard way Sanyo reported a new generation), the specifications stayed the same.To see how the batteries performed, I used an Ansmann Energy XC3000 battery tester. First, I measured the Eneloop AAA’s voltage. I recorded 1.29V, which is above the minimum of 1.2V that I’d expect from AAA cells. The next test was related to the time the Flash needed to recover and flash again.. also called the recycle time. The first shows the recycle time after the first 5 pops. The following results are interesting none the less. The Powerex 2700Pro is also made in Japan, and is to my understanding the equivalent to the all famous Sanyo 2700 and now called Panasonic 2700 (Evolta). The same year Sanyo announced their first high-capacity AAA Eneloop batteries, with a minimum of 900mAh and still rated for 500 cycles and an 85% charge left after one year. Some explanation about: 85% charge left after 1 year If you only have a time-based charger, you shouldn't buy Eneloop PRO batteries. First of all, because the timer duration will likely be set too short, the batteries won't be fully charged. Secondly, if the batteries are still half full, the charger won't stop until the timer has cut the charge. This means that the batteries are charged too long, and likely caused some damage.

The short answer: the Eneloop Pro battery has a higher capacity than the regular Eneloop with 2500mAh vs. 1900mAh. The Pro can be charged up to 500 times while the regular Eneloop up to 2100 times. The PRO batteries can provide more current than the regular Eneloops.The AA batteries also received an update and now powered a minimum of 2450mAh, with the same cycle life of 500. Take a look at the Specification of the Eneloop AAA PRO, called HR-4UWXB. And the product specifications of the AA PRO HR-3UWXB.
