3 Facts You Need to Know About Rechargeable Eneloop AA & AAA Batteries

When Eneloop batteries were first introduced in 2005, they claimed to last 1,000 charges. That sounded unbelievable, but Eneloop batteries held up to their end of the bargain.

Since then, the manufacturer has tweaked the battery’s cycle life and improved it significantly. You can now get up to 2,100 charges from the same batteries.

That’s 2100 fewer batteries you have to buy—talk about value for money. Besides the long rechargeable cycle life, let’s talk about what else you can expect from Eneloop batteries.

Eneloop Rechargeable Batteries Come in 4 Different Types

Eneloop rechargeable batteries come in different sizes. Although they all have the same basic chemistry, they have various capacities depending on the battery size.

Eneloop AA Batteries

Eneloop AA batteries look like standard AA batteries. They’re 50 mm in length and 15 mm in thickness.

They have a capacity of about 1900 mAh (milliampere hours), which means the batteries give you 1,900 milliamperes of current for 1 hour.

The nominal voltage of Eneloop AAs is 1.2 V, and it takes just over 3 hours to bring Eneloop AA batteries to full charge.

Eneloop AAA Size Batteries

Eneloop AAA batteries are 10.5 mm in diameter and 44.5 mm long. They typically have a lower capacity than AA Eneloop batteries of about 750 mAh.

The batteries have a nominal voltage of 1.2 V, and AAA Eneloop batteries recharge in just over 2 hours.

Eneloop Lite Cells

Eneloop lite batteries are about 30% lighter in weight than other Eneloop batteries. They’re designed for use in low drain devices like remote controls and video game controllers.

The Eneloop lite AA batteries have a capacity of 1,000 mAh, while the AAA version functions at a capacity of 600 mAh.

Eneloop Pro

The Pro version of the Eneloop gives the highest capacity (2,500mAh), making it suited for high output devices like LED lights, professional cameras, and gaming devices.

Eneloop Pro cells give a steady output of voltage. For instance, with Eneloop pro cells, you can repeatedly use the camera’s flash up to 800 times without the battery giving out.

Eneloop battery size Capacity(mAh) Voltage(V)
AA 1,900/2,000 1.2
AAA 750 1.2
Lite AA 1,000 1.2
Lite AAA 600 1.2
Pro 2,500 1.2
