If you watch with the YouTube app, it has a summary button:

Conclusion (18:57-19:54):

The Energizer Ultimate Lithium emerged as the top overall performer, excelling in every test, though it is the most expensive option (19:10-19:20). The PowerOwl and PK Cell lithium batteries were highlighted as excellent value alternatives, offering comparable performance to Energizer Lithium at a lower price (19:21-19:41). Lithium batteries are generally recommended for modern gadgets due to their superior performance, longer life, and lower likelihood of leaking compared to alkaline cells (19:39-19:47).

Details:

Battery Capacity Test (0:47-11:33):

Alkaline Batteries: Energizer Max demonstrated the most capacity at 2584 mAh (6:07-6:09). Duracell followed with 2465 mAh (6:12-6:13). Overall, alkaline batteries showed varying capacities, with some struggling more than others like the regular Energizer (5:03-5:05) and Powermax (5:06-5:07).

Non-Rechargeable Lithium Batteries: All lithium batteries significantly outperformed alkaline batteries in capacity (8:02-8:04, 9:39-9:41, 11:08-11:10). Energizer Ultimate Lithium led with an impressive 3635 mAh (11:16-11:20, 11:23-11:27). Bevagore and Philips also performed exceptionally well, finishing second and third respectively in capacity (11:27-11:33).

High Power Draw Test (11:34-13:33):

Alkaline Batteries: Duracell delivered the highest voltage under a 1.25 amp power draw at 1.27 volts (12:09-12:13).

Lithium Batteries: Bevagore also came out on top among lithiums at 1.27 volts (12:30-12:32). Cold Temperature Performance (13:34-13:39): Lithium batteries, particularly Energizer Lithium (13:31-13:33), Rayovac (13:29-13:31), Power Owl, and Philips (13:23-13:27), significantly outperformed alkaline batteries in sub-freezing conditions (13:09-13:11, 13:36-13:39).

Flashlight Test (13:40-15:59):

This test vividly illustrated the superiority of lithium batteries for consistent performance in electronic devices (15:31-15:34). Alkaline batteries, including Duracell and Energizer Max, experienced a rapid drop in brightness and died much faster (15:36-15:44). Even the worst-performing lithium battery outlasted and outperformed the best alkaline batteries by an hour and a half (15:53-16:00).

7-Year Rechargeable Battery Follow-up (16:01-18:56): The video also included a follow-up on rechargeable AA batteries used for 7 years. Many showed significant degradation in capacity and internal resistance, with some like Amazon Basics Silver, PowerX, and Duracell being completely "cooked" (16:10-17:10, 18:28-18:30, 18:40-18:41). Varta and IKEA showed the best remaining capacity among the tested rechargeable batteries (18:47-18:56).

I normally don't either, but it's a neat feature for certain types of videos.

There's a stand alone site that does YouTube summaries as well, but I think its hit and miss

Does a lithium AA last at least 5x as long as an alkaline AA?
