The 1.5V AAA Duracell Alkaline batteries are our reference batteries for comparing how other brands’ AAA batteries are performing, because as we know the Duracell Copper Top are performing very well, though they may not be the ones offering the highest capacity in various conditions. The 1.5V AAA Duracell Alkaline batteries we used for testing here were with an expiration date of 03-2019, so they are supposedly offering a long shelf life of 6 years, but what about the capacity they can provide…

We have started the test of the 1.5V AAA Duracell Alkaline batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 970 mAh as capacity and that is a very good result close to 1A. Increasing the constant current load to the higher values we use for testing the batteries continued to show very good performance and even in high loads they’ve managed to offer good performance. So it will be interesting to see how good other AAA size Alkaline batteries will compare in terms of capacity in our tests.

The performance of the 1.5V AAA Duracell Alkaline Batteries in our tests:

– 970 mAh at 0.1A load
– 777 mAh at 0.2A load
– 553 mAh at 0.3A load
– 336 mAh at 0.5A load

– 1.174 Wh at 0.1A load
– 0.916 Wh at 0.2A load
– 0.637 Wh at 0.3A load
– 0.378 Wh at 0.5A load

There are multiple battery sizes that are the most commonly used ones, these are the AAA, AA, C, D and 9V batteries that can be either primary (single use) as well as rechargeable. But these batteries also have many other names, some of which are used by different manufacturers and in some countries the other names may be more popular than the typical types mentioned above.

AAA Alkaline Battery – MN2400, LR03, E92, 4203/4003, K3A, AM4, 824, LR03, 24A, R03 (carbon–zinc), 24D (carbon–zinc)
AAA Rechargeable Battery – HR03 (NiMH), MIGNON, MINI-STILO, 4003, E92, K3A, R0, UM4, KR03 (NiCd), ZR03 (NiOOH)

The typical capacity of an AAA size alkaline battery is around 1000-1200 mAh, for Carbon-Zinc batteries the capacity is around 500 mAh and the rechargeable AAA batteries of the NiMH type usually offer abound 800-1000 mAh capacity.

AA Alkaline Battery – MN1500, LR6, E91, 4206/4006, KAA, AM3, 815, LR6, R6 (carbon–zinc), 15D (carbon–zinc)
AA Rechargeable Battery – HR6 (NiMH), MICRO, STILO, 4006, E91, KAA, R6, UM3, KR6 (NiCd), ZR6 (NiOOH)

The typical capacity of an AA size alkaline battery is around 1500-2500 mAh, for Carbon-Zinc batteries the capacity is around 500-800 mAh and the rechargeable AA batteries of the NiMH type usually offer abound 1600-2900 mAh capacity.

C Alkaline Battery – MN1400, LR14, E93, 4014, KC, AM2, 814, LR14, R14 (carbon–zinc), 14D (carbon–zinc)
C Rechargeable Battery – HR14 (NiMH), BABY, MEZZA-TORCIA, 4014, E93, KC, R14, UM2, KR14 (NiCd), ZR14 (NiOOH)

The typical capacity of a C size alkaline battery can be up to about 8000 mAh, for Carbon-Zinc batteries the capacity can be up to about 4000 mAh and the rechargeable C batteries of the NiMH type usually offer abound 4500-6000 mAh capacity. Alternatively there are also special plastic adapters that can be used together with an AA battery to make a C size cell, though the capacity would be lower in this case than what a C size battery would normally provide.

D Alkaline Battery – MN1300, LR20, E95, 4020, KD, AM1, 813, LR20, 13D (carbon-zinc), R20 (carbon-zinc)
D Rechargeable Battery – HR20 (NiMH), HR20, MONO, TORCIA, 4020, E95, KD, R20, UM1, KR20 (Ni-Cd), ZR20 (NiOOH)

The typical capacity of a D size alkaline battery can be up to about 12000 mAh, for Carbon-Zinc batteries the capacity can be up to about 8000 mAh and the rechargeable D batteries of the NiMH type usually offer abound 2000-12000 mAh capacity. Alternatively there are also special plastic adapters that can be used together with an AA battery to make a D size cell, though the capacity would be lower in this case than what a D size battery would normally provide.

9V Alkaline Battery – MN1604, 6LR61, 522, 4022, K9V, 6AM6, A1604, 6LR61, 1604D (carbon‑zinc), 6F22 (carbon-zinc), 1604LC (lithium)
9V Rechargeable Battery – HR9V (NiMH), HR9V, E-BLOCK, TRANSISTOR, 422, 4022, 6F22, K9V, 6HR61, 6KR61 (NiCd), 11604 (NiCd)

The 9V batteries essentially consists of multiple cells to bring up the voltage higher – 6x 1.5V cells for carbon-zinc; 3 cells for Lithium; 6, 7 or 8 cells for NiMH (7.2V, 8.4V or 9.6V) using 1.2V cells. Alkaline batteries can go up to about 500-600 mAh capacity, 400 mAh for the carbon‑zinc, up to about 1200 mAh for lithium (non-rechargeable), 200–300 mAh for NiMH and about 100 mAh for NiCd.
