It costs two or three times as much as the best alkaline AAA disposable battery. It is a similar price to the Panasonic Eneloop, but is not rechargeable. When compared with other AAA batteries, the Energizer Ultimate is quite an expensive choice. Pros: - Consistent power delivery - Outstanding shelf life - Excellent temperature range Best Disposable: Energizer Ultimate AAA Batteries It is worth buying these AAA rechargeable batteries with a charger if you don’t already have one, as Panasonic’s own model has smart features that charge each battery to the optimum level individually, and turn off automatically when full charge is reached. However, when they do need to be recharged they will take several hours. ![]() Unlike alkaline batteries that lose charge dramatically when the temperature drops, Panasonic Eneloop AAA batteries still function as low as -4 degrees Fahrenheit. The Panasonic Eneloop batteries again deliver market-leading performance, retaining up to 70 percent for a decade (when stored following manufacturer instructions). Second, many don’t hold their charge while not in use. First, a lot of them need to be charged before use, whereas these are pre-charged at the factory using solar energy (you may also be interested in our article about the best solar batteries ). ![]() Panasonic’s Eneloop AAA batteries also overcome two of the notable drawbacks of many rechargeable NiMHs. We researched all the leading brands to get a comprehensive view of the market. Our main aim with this AAA battery review is to explain the different types of triple-A batteries, and give examples of the best of each type via our top picks. Best Overall: Panasonic Eneloop AAA Batteries - Best Disposable: Energizer Ultimate AAA Batteries - Best Budget: Amazon Basics AAA Batteries - Best Alkaline: Duracell CopperTop AAA Batteries - Best for Flashlights: Panasonic Eneloop Pro AAA Batteries How We Picked the Best AAA Batteries To help you find the right combination of power and value, we've rounded up the best AAA batteries to serve your needs. ![]() While all AAA batteries are the same physical size, their performance, durability, and cost can vary considerably. These tiny powerhouses deliver the same 1.5V output as a AA battery, but they are smaller and lighter so the gadgets they are used in can be more compact. They're found in dozens of devices from digital cameras and drones, to blood pressure monitors and laser levels. ![]() Cells Per Battery: 1 Lithium Content: 0.075g Individual Battery Weight: 7.9g Origin: Designed in U.S.AAA batteries (also known as triple-A batteries) power all kinds of devices, from the recreational to the essential. But in normal circumstances a battery installed in a device, like a door lock, will last ~12 months. High ambient temperatures, and higher humidity, increases the internal drain. The battery life in dormant mode depends partly on the environment. This is one of the advantages of a lithium ion battery with a control circuit, vs an alkaline or NiMh battery, where the cell discharges directly into the circuit (no control circuit). Other Safety Protections: Protects against Overload, Leakage, Short Circuit, Over Voltage, & High Temperature Certifications: IEC 62133, CE, FCC, PSE, UN38.3, RoHS, REACH Operating Temperature Rage: -20c -> 60c, (-4F-> 140F) Self-Discharge: The dormant / self discharge characteristics of Pale Blue batteries are very low. Chemistry: Lithium Ion Power: 900 mWh Voltage: 1.5V Capacity: 600 mAh Charge Time: 60 minutes (depending on charger specifications) Cycle Rating: 1000+ Cycles Charging Cable: 1 USB-A to 4 USB-C Charge State Indicator: Green LED Protection Circuit: Integrated safety circuit protects battery and device Overheat Protection: Operating at max output the battery will not overheat, this is part of the protection circuit.
