2nd place in laboratory testing: ANSMANN Extreme Lithium AA with a top score of 1.1
The ANSMANN Mignon AA 1.5V Extreme Lithium battery secured a strong second place in the BILD buying guide laboratory test, earning a grade of 1.1 (very good).
In the latest AA battery lab test by BILD-Kaufberater, the ANSMANN Mignon AA 1.5V Extreme Lithium secured a strong second place with an overall grade of 1.1 (very good). Our lithium AA demonstrates the capabilities of modern cell technology: very high usable energy and capacity, along with excellent results under high (200 mA) and very high (800 mA) loads. Wherever performance matters, ANSMANN remains stable and reliable for longer.
- Test: BILD-Kaufberater – "Lab test reveals: These AA batteries impress in performance, runtime, and price"
- Updated on: 05/28/2026
- Ranking: 2nd place | Test grade: 1.1 (very good)
- Load profiles tested: 50 mA and 200 mA; additional stress test at 800 mA
Why this test is so relevant
Not all AA batteries are the same. On the shelf, alkaline and lithium batteries sit side by side, but in practice, they differ significantly under load. BILD-Kaufberater compares both technologies in the same format, evaluating usable energy (mWh), usable capacity (mAh), and voltage curve. Additionally, an 800 mA stress test reveals which cells have reserves even in extremely demanding devices. The result: under high and very high loads, the performance gap widens noticeably—this is where lithium shows its strengths.
Our result: 2nd place with a top grade – strong performance when it counts
The ANSMANN Mignon AA 1.5V Extreme Lithium achieved an overall grade of 1.1 (very good), sending a clear signal for demanding applications:
- Very high usable energy and capacity
- Particularly strong at 200 mA (continuous load) and 800 mA (stress test)
- Stable voltage curve – devices run longer in their optimal range
In short: When your application demands power, ANSMANN delivers reliably – with constant voltage and high energy reserves.
What does this mean for practical use?
- High-performance LED flashlights: Longer, consistent brightness without early voltage drop.
- Professional equipment: Radios (transmitting), measuring devices, sensors – stable power supply even under continuous load.
- Toys & model building: High continuous currents without premature power loss.
- Outdoor & photography: Lithium remains lightweight, temperature-stable, and has a long shelf life – ideal for sub-zero temperatures and long trips.
For those operating devices with moderate power needs (remote controls, clocks, simple lights), good alkaline cells remain an economical choice. Where performance, robustness, and weight are critical, lithium is the winner.
Why our Extreme Lithium performs so well
- High energy density: More usable energy per cell
- Constant voltage: Devices operate in their optimal range for longer
- Temperature tolerance: Reliable in both cold and heat
- Low self-discharge: Long shelf life, ready for immediate use
- Lightweight: Noticeably easier to carry and use
The combination of high energy output and voltage stability makes all the difference in the field – especially at 200 mA and 800 mA, as the test impressively demonstrates.
How the test results compare
- 1st place: Energizer Ultimate AA (Lithium) – Test winner
- 2nd place: ANSMANN Mignon AA 1.5V Extreme Lithium – very good (1.1)
- 3rd place: Varta Ultra Lithium AA – very good
Our conclusion: In the load ranges that matter most in practice, ANSMANN delivers top performance – with first-class stability and strong energy output when it counts.
