![]() ![]() It endured 1,500 recharge cycles for depth of discharge (DOD) 60% and held 85% of the charge after one year and 75% after three years. The second generation of Eneloop AA and AAA batteries was introduced in 2010. The part numbers for first generation cells are HR-3UTG (AA) and HR-4UTG (AAA). They could be recharged 1,000 times and held up to 75% of their charge after one year. The original Eneloop batteries were introduced in AA and AAA size, with capacities of 2,000 mAh and 800 mAh. ![]() The discontinued Eneloop Plus was similar to the standard Eneloop, with overheating protection.Įneloop A newer Panasonic Eneloop (top) and older Sanyo AA Eneloop batteries 1st generation Numerical data are listed in the variant comparison tables section. The more expensive Eneloop Pro has significantly higher capacity and is suitable for higher-current applications, but has poorer charge retention and shorter lifespan in charge cycles total lifetime capacity in watt-hours is much less than the other versions. The cheaper Eneloop Lite has lower capacity and a longer lifespan in charge cycles, but the standard and Lite of about the same time have very similar total lifetime capacity in watt-hours. The Eneloop is the standard general-purpose cell. The Eneloop Lite series traded significantly lower capacity for longer lifespan, and also faster charging and lower weight. The trade-off was modified for the Eneloop Pro series, providing higher capacity but with more self-discharge and shorter lifespan. Eneloop batteries were designed in a way that traded off somewhat lower capacity for much slower self-discharge. The thin insulators allowed significant leakage, leading to relatively short self-discharge times. This was done by using thinner insulators internally, allowing more of the active components to be used and thus increasing capacity. Technology Īfter NIMH rechargeable batteries were introduced, they were developed to increase capacity. Panasonic retained the "Eneloop" trademark, sourcing the batteries from FDK (formerly Sanyo) factories. In exchange for US FTC approval of the takeover, Panasonic agreed to sell Sanyo's portable NiMH battery business to Fujitsu subsidiary FDK in order to preserve competition, and later did so. There are also counterfeits of Eneloop and other well-regarded brands.īecause they can replace a large number of alkaline batteries over their life cycle, Eneloops are marketed as being eco-friendly. Those made in Japan are all made in the same factory, but not necessarily to the same specification as the Eneloop brand. ![]() By 2020 most NIMH batteries available were of this type, with varying capacity, self-discharge rate, and lifespan. Since Sanyo introduced the Eneloop, many other brands of low-self-discharge batteries became available, described as "low self-discharge","LSD", "pre-charged", or similar. Since then many other makes of NiMH batteries are supplied precharged, with long charge retention. Įneloop cells lose their charge much more slowly than the 0.5–4% per day loss of previously available NiMH batteries, retaining about 85% of their charge for a year after charging This allows them to be sold precharged. Panasonic acquired a majority stake in Sanyo in 2009, and Eneloop batteries were thereafter branded, but not manufactured, by Panasonic.
