Eneloop batteries: The best!

Short intro before you check out all the pages?

Before you are heading to the eneloop 2005-2017 battery library, or the complete lineup of chargers I would like to give a short and basic introduction to eneloops.

The Eneloop AA battery was first being introduced in November 2005 by Sanyo with nothing less than breathtaking specifications. They were able to be charged 1000 times, (something very unique in those days) and were keeping their charge much longer than any other rechargeable battery on the market (called Low Self Discharge). Another specification that stood out was that you were able to use them right out of the box. While the traditional rechargeable batteries had to be charged before using, the eneloops were Ready-to-use because they came pre-charged at 70% of their max capacity. These are just a few reasons for using eneloops. Their full capacity is min. 1900mAh, and sometimes packages show Typ. 2000 mAh.
Expanded line-up
In 2007 Sanyo also produced C and D size batteries and in 2009 their first Eneloop Special edition.

In 2010 they produced their first Low capacity version, (for low-drain devices) called Eneloop Lite. Their capacity was about 950 mAh for their AA-size batteries.
In the same year a High capacity version (for high-drain devices) was also produced and was called Eneloop XX/PRO, with a capacity of 2400mAh for their AA batteries. The year that Sanyo became a Panasonic company.

Eneloop charging and chargers

Do you know how to charge your eneloop batteries?

Fortunately Sanyo and Panasonic also produced chargers alongside their batteries so that you don`t have to worry about all this charging stuff.
Both, Sanyo and Panasonic made some interesting chargers. The sad thing is that not all of their chargers are good

Some of them charge a pair of batteries for X amount of hours, and then stop. These are sometimes called Dumb chargers...... They are time-based chargers.

Better chargers use more sophisticated technology to measure whether a battery is fully charged or not, and these are referred to as Smart chargers or battery analyzers.

Eneloop Products

More than just batteries

Sanyo introduced in 2006 the eneloop Universe.
This expanded the concept of eneloop.  Eneloop Universe received the 2007 Good Design Award with their intuitive products.

This lineup included an eneloop lamp, portable solar charger, neck warmer, bicycles and much more.

With the official closing of the Sanyo trademark in Japan in March 2012, the lineup of "eneloop universe" stopped as well. Some products like the mobile boosters were being improved and sold under Panasonic branding.
