Another noticeable difference between them is in the recharging capacity. Eneloop Pro rechargeable batteries can be recharged up to 500 times. Battery life based on testing method estabilished by IEC 61951-2 2011(7.5.1.3). 1000 times based on IEC 61951-2 2017 (7.5.1.4) Varies according to conditions of use. Next, I cycled the batteries 50 times, taking capacity readings every 10 cycles. From the graph, you can see that the batteries constantly exceeded the rated capacity, and there was little variance between readings. Due to having lots of similarities, I couldn’t find much difference between Eneloop Pro and Eneloop batteries. Capacity:

Eneloop Pro batteries are not suitable for applications where the battery is continuously charged and used at the same time. 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.** After a recent takeover Panasonic now manufacture the Eneloop range, and continue to produce premium rechargeable batteries.For camera flashes, flashlights, and power-hungry electronic devices, you won’t find a better choice than Eneloop Pro in this price tag.

It's worth bearing in mind that alkaline non-rechargeable cells look good on paper, with around 1700-2850mAh for AA and 860-1200mAh for AAA. However, that’s not the whole story when comparing Eneloop and alkaline batteries, which we’ll come to in our ‘performance’ section. The chemical makeup of Ni-MH batteries allows the cell to be recharged at any time without having to be fully discharged. Those who are looking for more battery capacity to power heavy-duty electronic devices must go for Eneloop Pro. The very latest 5th Generation of Panasonic Eneloop Pro AA 2500mAh Rechargeable Batteries for professional use are AA size NiMH 1.2V rechargeable batteries. 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.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 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. According to the spec sheet, Eneloop batteries are rechargeable NiMH batteries that are affordable and reliable. Finally, Eneloop and Eneloop Pro Batteries, Which One Should I Buy? https://www.reddit.com/r/xboxone/comments/4gqe2n/best_rechargeable_batteries_eneloop_vs_eneloop_pro/

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 Batteries The first difference you will notice among them is in their capacity. Where Eneloop batteries come with 1900 mAh, Eneloop Pro has 2500 mAh. 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. The answer to the question, Eneloop vs Eneloop Pro, which one is the best must be clear to you now. eneloop batteries utilize a highly-durable super lattice alloy which prolongs the life of this important material. Improvements to this super-lattice alloy have increased hydrogen stability resulting in reduced self-discharge and long lasting, stable voltage output.Due to having a higher capacity than regular AA batteries, you will get at least 25% longer runtime with Eneloop Pro. You may have heard about Eneloop Pro batteries being one of the most powerful NiMH batteries in the market. And, Eneloop standard ones are one of the most durable ones. Many customers will have known and used batteries under the Sanyo brand name. Panasonic Eneloop Pro AA batteries are the ideal choice for powering high drain devices such as digital cameras, flashguns or photo strobe flash lights. The Panasonic Eneloop Pro AA batteries provide more than twice the number of flashes per recharge in less than half the time, compared to conventional alkaline batteries. The batteries are also perfect for wireless keyboards, wireless mice, game controllers, radio controlled toys and a range of everyday electronics. Many customers will have known and used the batteries under the Sanyo brand name. 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. The Panasonic Eneloop Pro AA batteries provide more than twice the number of flashes per recharge in less than half the time when compared to conventional alkaline batteries. Also perfect for wireless keyboards, wireless mice, game controllers, radio controlled toys and a range of everyday electronics. 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.

Another win in terms of performance is that Eneloop Pro batteries keep on working in the harshest of conditions, so the weather needn’t stop play. Indeed, they’re rated as fully functional in temperatures from -20 to + 50 degrees Celsius. Verdict Testing 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.In this comparison, both battery types belong to the same company, Panasonic. So, I am not going to repeat the details of the manufacturer. On the other hand, standard Eneloop batteries can be recharged up to 2100 times making it more convenient for less powerful devices. Shelf Life: 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.
