Anker AAA battery has about 10% improved capacity vs Energizer Industrial AAA
Anker = 1289 mAh
Energizer = 1164 mAh
This is a great improvement in already mature market
41.5 hrs into capacity test @25mA current, Anker AAA has started to show improved capacity vs Energizer Industrial AAA. So far both are at 1038 mAh capacity.
I’ll let it go till voltage drops to 0.8V and that will determine the final capacity of these.
Some Testing Updates:
Battery is 18 hrs into test and is holding similar or better then Energizer Industrial AAA. It will be another 18-20 hrs to finish the capacity test. This is a discharge test (@25 mA) till the voltage of battery drops to 0.8V. This test is ongoing and will be updated once complete…Duracell AAA result will be included later since I only can spare 2 circuits for these tests
Internal Resistance of the battery: I used AC impedance test (@1KHz) to check the internal resistance of these batteries (also called impedance). “lower the better” This value typically is between 150-300 mOhm.
Energizer Industrial : 131 mOhm "Best one"
Duracell : 178 mOhm
Anker : 164 mOhm
I received Anker AAA Alkaline Batteries (24 pack). Below are some of the unboxing pictures. I’m currently running some discharge test in my battery lab comparing these with Energizer Industrial AAA. That will be done by tomorrow morning so I’ll update this with test results. I’ll compare these with Duracell AAA as well starting tomorrow.
Packaging: Comes in classic Blue/White paper box (100% recyclable)
There are 3 x 8 pack batteries inside along with a Happy/Not Happy card. Date code on battery is 05/2029 (almost 10 year life).
Out of box the batteries have a voltage of 1.65 V. According to IEC LR03 standard these batteries are considered dead (fully discharged) when the voltage drops to 0.8 V. We will see how these perform
At this time there is not much to discuss (more after battery tests are done).
