It has excellent ratings on Amazon - an average of 4.6 out of 5 stars from about 300 reviewers. The PowerEx MH-C9000 is one of the more sophisticated NiMH AA battery analyzers/chargers available. PowerEx MH-C9000 WizardOne Charger-Analyzer How about some good battery chargers to go with these batteries? The chargers featured below are some of the smartest out there - they have built-in protection to prevent overcharging or undercharging. However, on average most people will charge their batteries about 100-200 times over a 5-year period. Their only potential downside is that they can be charged 500 times - not 2100 times like the regular Eneloops.
BEST DURACELL RECHARGEABLE BATTERIES PRO
The Eneloop Pro has a capacity of 2500 mAh –this is 500 mAh more than the regular Eneloops. The Eneloop Pro is a high-capacity version of the regular Eneloop cell. Note that these links to the second-generation 2000 mAh eneloops.

They are also available with a charger: 8 Eneloop Batteries with a Charger. The charge times are as follows: AA Eneloops charge in 230 minutes, and AAA Eneloops charge in 135 minutes.Įneloop batteries are available at Amazon in 8 packs, 16 packs, and 32 packs. The AA-sized Eneloops are rated at 2000 mAh, and the AAA-sized Eneloops are rated at 800 mAh (mAh stands for “MiliAmp hours” - a unit that indicates how much energy a battery can hold.) Panasonic recommends keeping the batteries in a cool location to maximize charge retention. After five years, they retain 70% of their charge (stored at 20 degrees Celsius). After 6 months, they retain 90% of their charge. Eneloops can be recharged up to 2100 times, and they will retain their charged capacity even after years of storage. Eneloop Rechargeable Batteries by Panasonicīetter designed than other rechargeables, Eneloop batteries have become a best-selling battery. I do not recommend the Energizer or Duracell rechargeable batteries - these name brands seem to produce inferior rechargeables, perhaps to protect their sales of alkaline batteries. These are Panasonic’s Eneloops, Duracell, Energizer, and Sony. The Eneloop Pro batteries from Panasonic hold their charge the longest, and they are my top recommendation. Generally, the best low self-discharge batteries are made in Japan (the others are made in China). However, they are ideal for high-drain electronic devices like digital cameras, which outperform alkalines. Because they can hold their charge for so long, they are suitable for low-drain devices like remote controls and flashlights. These batteries have a lot going for them: they come fully charged (like alkaline batteries), and they can hold their charge over many months (unlike regular Ni-MH rechargeables). Today, the best rechargeable batteries are the “low self-discharge” Nickel-Metal Hydride (Ni-MH) cells. These Powerex are also low-discharge, high-capacity batteries ( 2400 mAh), but they do not perform quite as well as the Eneloop Pro (see this review for the details on their performance). For example, if you charged your batteries twice a week consistently, it would take 5 years to reach 500 charges.Īlso worthy of consideration is the Powerex battery, which is cheaper than the Eneloop Pro. But most people will never charge their batteries that many times. They can only be charged 500 times (versus 2100 times for regular Eneloops).

They have a high energy capacity (2550 mAh), and they perform better than similar high-capacity AAs. Overall, the best rechargeable AA battery is the Eneloop Pro. If you are on a budget, don’t mind a little less performance from your batteries - get the Powerex AAs (about $10 for a pack of 4).If you want maximum recharge capacity (2100 times) - get the 4th Generation Panasonic Eneloops (about $11 for a pack of 4).If you want the best energy capacity (2550 mAh) - get the Eneloop Pro (about $18 for a pack of 4).Here are my recommendations for the best rechargeable AA batteries:
