AAA or triple-A batteries refer to standard-sized cells measuring at least 44.5 mm in length, and with a diameter of 10.5 mm. More precisely, the anode is 3.8 mm in diameter, while the cathode has a diameter of 4.3 mm.
They are larger than standard AAAA batteries and smaller than AA batteries, as such, they are easily the most commonly used batteries at home, work, or in-play gadgets.
Energizer offers a wide selection of reliable and long-lasting triple-A batteries, some of which are rechargeable while others are non-rechargeable.
It may be hard to select the correct triple-A batteries for your devices with so many choices at hand. That’s why we help you compare the five main types of Energizer AAA batteries to ensure you always make the right choice.

An Overview of Energizer AAA Batteries
Below is a detailed description of each of the Energizer AAA battery types.
Energizer MAX AAA
Energizer Max AAA battery is the world’s first mercury-free Alkaline battery that features a responsible and environmentally-friendly design. These alkaline batteries have a pure electrolytic manganese dioxide and a carbon conductor, while the anode is a gel-like mixture of zinc powder and electrolyte.
The Energizer Max AAA battery encompasses Powerseal Technology, which protects your devices against leakage for up to two years after they’ve been thoroughly used and left in low-drain devices. You can also rely on their power for up to 10 years when stored appropriately.
You should store them at temperatures between -40°C to 50°C. However, storing them at temperatures below 20°C makes them lose about 3% of their capacity per year as cold temperatures slow down chemical reactions.
They are suitable for all your everyday low-to-medium drain devices, like remote controllers, digital cameras, and toys.
Energizer Ultimate Lithium AAA
Energizer Ultimate Lithium AAA batteries are long-lasting and best suited for high-tech devices. These produce 1.5 volts of electric charge, resulting from active lithium metal reacting with iron disulphide. They contain a non-aqueous electrolyte, which is a mixture of lithium salt and an organic solvent.
Ultimate Lithium AAA’s chemical composition makes them 33% lighter in weight than all other triple-A batteries in this range. It also enables them to function even in extreme temperatures as low as -40°C to 60°C.
They’re leak-proof and come with a leakage guarantee that warrants a device repair or replacement by the manufacturer, provided you follow the applicable terms and conditions.
Energizer Recharge Plus AAA
Energizer Recharge Plus AAA is the world’s first rechargeable battery made using 4% recycled materials. In addition, these Nickel Metal Hydride (NiMH) batteries feature an innovative technology that allows them to power high drain devices, such as digital cameras, handheld game controllers, and high-powered toys.
The advanced technology also extends the battery's life span by decreasing self-charge and natural aging effects.
They come precharged, and you can recharge them up to 500 times. Their capacity is approximately 75% of the alkaline triple-A batteries for low drain applications and can surpass alkaline battery performance when used in high drain devices.
Energizer Recharge Plus AAA batteries have a limited lifespan of 5 years or less, depending on usage. When not in use, they can hold 50-80% of their charge for up to 12 months when.
Storing them under high temperatures increases reaction rates and causes them to self-discharge faster.
Maintaining the following general environmental guidelines will ensure ultimate performance.
- Storage: -20ºC to 30ºC (-4ºF to 86ºF)
- Charge: 0ºC to 40ºC (32ºF to 104ºF)
- Discharge: 0ºC to 50ºC (32ºF to 122ºF)
- Humidity: 65±20
Energizer Recharge Universal AAA
The Energizer Recharge Universal AAA batteries employ similar chemistry to the Recharge Power Plus.
Among other similarities are that both have a nominal voltage of 1.2 volts, last up to 5 years, and operate under the same temperatures. They are manufactured using 4% recycled batteries and make their way to you already pre-charged.
However, there are some significant differences between them.
| Energizer Recharge Power Plus AAA | Energizer Recharge Universal AAA | |
| Rated Capacity | 800 mAh | 700 mAh |
| Typical Volume | 0.42 oz | 0.39 oz |
| Maximum Charge Cycle | Up to 500 times | Up to 1000 times |
| Model Number | ENERGIZER NH12-800 (HR03) | ENERGIZER NH12-700 (HR03) |
| Designation | ANSI-1.2H1 IEC- HR03 | ANSI-1.2H1 IEC- HR03 |
Frequently Asked Questions
Can You Use an AAA Battery in Place of an AA Battery?
No. Why? The main reason is that the two vary in size; hence a AAA cell will not make proper contact when placed in a holder meant for an AA battery. However, you can use a converter to make it possible. Unfortunately, even when you do, the triple-A will power a device for a shorter period because it is smaller and has less capacity than the AA cell.
