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? Those who are looking for more battery capacity to power heavy-duty electronic devices must go for Eneloop Pro. 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.

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. The very latest 5th Generation of Panasonic Eneloop Pro AA 2500mAh Rechargeable Batteries for professional use are AA size NiMH 1.2V rechargeable batteries. Due to having lots of similarities, I couldn’t find much difference between Eneloop Pro and Eneloop batteries. Capacity:These Panasonic Eneloop Pro AA batteries have been developed by Panasonic and are pre-charged NiMH energy units that have a high capacity. Not only are they highly efficient and durable but they also have a long life cycle between charging. This makes them perfect for electrical equipment that needs power for extended periods of time. With a low level of self-discharge cells will maintain around 85 per cent of their power even after 12 months in storage. As a result, the batteries can be left in electrical devices or kept in reserve for long periods, and still maintain their power levels for when needed. The Eneloop Pro AA have a rated capacity of 2500mAh, which puts them near top of the pile in this category of batteries. They’re designed for the most demanding of applications, such as camera flashes and radio-controlled cars. 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. Benefits of Using Eneloop Pro Batteries Due to having a higher capacity than regular AA batteries, you will get at least 25% longer runtime with Eneloop Pro. 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.

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.** 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. The first difference you will notice among them is in their capacity. Where Eneloop batteries come with 1900 mAh, Eneloop Pro has 2500 mAh.

Eneloop Pro batteries are not suitable for applications where the battery is continuously charged and used at the same time. Another noticeable difference between them is in the recharging capacity. Eneloop Pro rechargeable batteries can be recharged up to 500 times. For camera flashes, flashlights, and power-hungry electronic devices, you won’t find a better choice than Eneloop Pro in this price tag.
