5 g lighter than a Kirkland alkaline AA and 8 g lighter than an Eneloop NiMH AA

the heaviest lithium battery tested up to that point in the video

the heaviest lithium battery tested up to that point at its position in the video

nearly a gram lighter than Smart Tools

by far the lightest lithium battery tested

second-lightest lithium battery tested

same as Smart Tools

same as the Kirkland alkaline reference battery

the largest diameter of all 11 lithium brands

rated 2,600 mWh / 1,733 mAh, actually produced 1,470 mAh

rated 3,000 mWh / 2,000 mAh, actually produced 1,988 mAh, described as very impressive and coming very close to its rating

rated 2,960 mWh / 1,973 mAh, actually produced 1,751 mAh, taking the capacity lead from Optic Plus at that point

rated 2,800 mWh / 1,866 mAh, actually produced 1,606 mAh, taking the capacity lead from Smart Tools at that point

rated 2,600 mWh / 1,733 mAh, actually produced 1,436 mAh, almost 300 mAh short of its rating

second-longest of the 11 lithium brands (after Vapcell)

third-longest of the 11 lithium brands

explicitly identified in the transcript as 'the second least expensive brand,' which by price matches Optic Plus

the first (worst) lithium brand to give up in the fan endurance test

second-worst of the 11 lithium brands

third-worst of the 11 lithium brands; also struggled with RPM from the start of the fan test, running noticeably slower than most other brands

dropped only to 1.43 V, doing well at the start of the test

dropped to 1.43 V, the best (highest) reading up to that point

dropped to 1.25 V

dropped to 1.4 V

dropped to 1.41 V

dropped to 1.39 V

dropped to 1.4 V

a pretty big drop to 1.25 V at the start of the test
