For camera flashes, flashlights, and power-hungry electronic devices, you won’t find a better choice than Eneloop Pro in this price tag. Next, I tested the capacity using the high-drain test (600mA +/-20%). Initially, I saw the batteries return a capacity of 2894mAh, which is considerably higher than the rated capacity. https://www.reddit.com/r/xboxone/comments/4gqe2n/best_rechargeable_batteries_eneloop_vs_eneloop_pro/ On the other hand, standard Eneloop batteries can be recharged up to 2100 times making it more convenient for less powerful devices. Shelf Life:

Due to having a higher capacity than regular AA batteries, you will get at least 25% longer runtime with Eneloop Pro. The batteries are rated to last for 500 cycles, which isn’t terrible (the Duracell Rechargeable AA 2500mAh are designed to last for only 400 cycles – but they are cheaper), and maintain a decent 85% of their charge for a year. This makes the Eneloop Pro AA units a good choice for those who charge and store batteries, ready for action. Performance For longer shelf life, low discharge rate, and durable build quality, you can rely on Eneloop batteries for powering sensitive equipment. Eneloop batteries have been developed to produce a 800mAh NiMH cell with a self-discharge rate of no more than 15% per year and only 30% over 3 years.Although most widely known for its cell phones and other household electronics, Sanyo has helped pioneer many technological advances in the battery industry. Their Eneloop line of batteries was created to provide consumers with a series of rechargeable batteries with an extremely low self-discharge rate. Battery life based on testing method estabilished by IEC 61951-2 2011(7.5.1.3). 150 times based on IEC 61951-2 2017 (7.5.1.4) Varies according to conditions of use.

In this comparison, both battery types belong to the same company, Panasonic. So, I am not going to repeat the details of the manufacturer.

The very latest 5th Generation of Panasonic Eneloop Pro AA 2500mAh Rechargeable Batteries for professional use are AA size NiMH 1.2V rechargeable batteries. Another noticeable difference between them is in the recharging capacity. Eneloop Pro rechargeable batteries can be recharged up to 500 times. Due to its amazing characteristics, Eneloop is considered eco-friendly as it can replace a few alkaline batteries in its lifetime. Benefits of Using Eneloop BatteriesTesting the Eneloop Pro AA, I used the Ansmann Energy XC3000 battery tester. I first started by testing the initial voltage with the batteries fully charged. For NiMH batteries, this should be at least 1.2V, although these measured in at 1.36V. Of course, voltage will drop over use, but you need the right starting level to ensure their capacity can be realised. Regular disposable AA and AAA batteries are considered Primary Cells, more widely recognized as conventional “alkaline” batteries. 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). The electrodes are surrounded by an alkaline electrolyte, the chemical from which alkaline batteries get their name. https://www.bhphotovideo.com/c/compare/Panasonic_eneloop_vs_Panasonic_eneloop_pro/BHitems/1491680-REG_1258154-REG The chemical makeup of Ni-MH batteries allows the cell to be recharged at any time without having to be fully discharged. eneloop pro Ni-MH “Low Self Discharge” batteries utilize Panasonic’s advanced rechargeable battery technology providing up to 2550mAh* of power (AA batteries) and the ability to be recharged up to 500 times.**

While choosing one, one can easily get puzzled between two. Hence, this Panasonic Eneloop vs Eneloop Pro comparison will help you get a clear picture, and help you decide between the two.After a recent takeover Panasonic now manufacture the Eneloop range, and continue to produce premium rechargeable batteries. Australia, Brazil, Canada, China, CIS, Europe, Hong Kong Region,India, Indonesia, Japan, Korea, Malaysia, Myanmar, Anything with the word ‘Pro’ tagged onto the product name has to be better, right? The Eneloop Pro AA and AAA NiMh rechargeable batteries certainly look a better bet than their standard Eneloop siblings for powering gadgets with a heavy current drain, thanks to their greater capacity. That’s certainly good to have but it comes at the cost of longevity, as you can’t recharge them as often over their lifetime. Even so, 500 recharging cycles should see you through and they’re hardly any more expensive to buy than the standard version, if you shop around a bit.

The Eneloop Pro AA are the company’s professional-level batteries, designed to deliver the greatest amount of power. In this regard, they certainly deliver; but these batteries are relatively expensive and offer a fewer number of charge cycles next to the competition. Design and Charges

Retain up to 85% of their charge after a full 12 months in storage and lose as little as 30% in 36 months Do not use in water-proof flashlights or in any device with an airtight battery compartment. Doing so may result in explosions or leaks that may cause personal injury. Right now, Eneloop Pro batteries are one of the powerful batteries with NiMH construction. It is entirely made in Japan ensuring the highest possible quality.
