- Panasonic eneloop 4 x 800 mAh batteries AAA size
How long can I expect the Panasonic Eneloop batteries to last in my devices?
The longevity of the batteries will depend on the device and usage, but Eneloop batteries maintain 70% of their charge for up to 5 years, ensuring reliable performance.
Can I use these batteries in high-drain devices?
Yes, Eneloop batteries are designed to deliver consistent power performance and can handle higher discharge currents, making them suitable for high-drain devices.
Are these batteries safe to use in extreme temperatures?
Yes, the Panasonic Eneloop batteries perform well in extreme temperatures, functioning effectively down to -20° C.
Can I recharge the batteries if they are only partially drained?
Absolutely! Eneloop batteries can be recharged whether they are fully or partially drained, making them convenient for regular use.
What makes Eneloop batteries different from regular Ni-MH batteries?
Eneloop batteries utilise advanced technology that significantly reduces self-discharge, allowing them to hold their charge longer and be recharged many more times than standard Ni-MH batteries.
Are the Eneloop batteries pre-charged and ready to use?
Yes, the Eneloop batteries come pre-charged using solar power at the factory, so they are ready to use straight out of the package.
How many times can I recharge the Eneloop batteries?
You can recharge the Panasonic Eneloop batteries up to 2100 times, making them a cost-effective and eco-friendly choice.

Eneloop is a modified Ni-MH battery
To understand the modifications done to the eneloop batteries, it helps to understand the construction of a typical Ni-MH battery.
Basic construction of Ni-MH batteries
like most other rechargeable batteries, consist of two metal stripes - the positive and negative electrode. Between these metal stripes an insulating foil, the separator, is placed. This sandwich of three layers is rolled-up to a coil and placed into a metal can, which acts as a negative pole of the battery. Before closing the can with a cap, a liquid, the electrolyte, is filled into the can. The cap contains a gas release vent, which allows to release hydrogen when the battery is overcharged. The electrical behaviour of the battery depends on the composition of the electrodes, on the separator and on the used electrolyte.
Self-discharge in Ni-MH batteries
Modern Ni-MH batteries consist of two metal stripes (anode and cathode), which are separated by a non-conductive porous plastic foil (separator). These three stripes are laid on top of each other and are wound to a coil. This coil is put in a metal can and immersed with a liquid (electrolyte). Then the metal can is closed with a cap.
How could the self-discharge be reduced?
The chemical decomposition of the cathode has been reduced substantially by the use of a new superlattice alloy. As an additional benefit, the superlattice alloy increases the electrical capacity of the battery and reduces the internal resistance, which allows higher discharge currents. Another advantage of the super-lattice alloy is that less cobalt is needed to stabilize the compounds' structure. The anode has been strengthened by another new material, which reduces the natural disaggregation. Additionally, the separator and the used electrolyte have been optimised for low self-discharge of the Eneloop.
Which changes have been made for the new Eneloop?
The technological difference between the "old" and the "new" Eneloop is, that the super-lattice-alloy of the "new" Eneloop has been even more improved.
Advanced materials
Development of a highly-durable super-lattice alloy. The durability of Panasonic's original super-lattice alloy, a negative-electrode material used in Eneloop, has been enhanced by homogenizing the crystalline structure (a reduction of crystals with an irregular atomic order is irregular) as well as improving its composition (the ratio of constituent element) to reduce the deterioration of the super-lattice alloy by repeated charge and discharge
Advanced manufacturing method
Developed technology to protect the surface of the superlattice alloy. A new additive to the negative electrode material, super-lattice alloy, and a new additive coating technology was developed. By protecting the alloy surface, deterioration of the super-lattice alloy by repeated use can be reduced.
Advanced structure
Use of strong/thin outer case. The new Eneloop adopts the same strong/thin outer case used for Panasonic's industry-leading level high-capacity AA-size rechargeable batteries, the Ni-MH 2700 Series. This improves the internal cell space efficiency and optimizes the balance of battery components, leading to an increase in the number of times a battery can be recharged.
