The quick take
The short version of why each pick lands where it does, built straight from the measured results.
“Looking at just performance and not the price, the blinks power which is a lithium cell came out on top with an average finish of 2.3... If one factors price into the equation, power out [Power Owl] moves from second place to first, in my opinion it's a great battery for a fair price and would definitely be my choice.”
Best in 1 of 3 measurements, including Subfreezing test.

Active Energy
- 296-year rechargeable AA battery durability retest (separate segment)
the only battery in its final test group functioning properly at the full 700 mA target, but only in service about 5 years versus 6 for the others

Varta (rechargeable, about 5 years old)
- 296-year rechargeable AA battery durability retest (separate segment)
lost about 250 mAh of capacity since last tested; transcript renders this group's results as 'Thunderbolt... 1,634 mahs Rayovac and V... 997 and 1,960', which reuses brand names (Thunderbolt, Rayovac) already assigned to unrelated single-use alkaline products earlier in the same video; this pairing could not be confidently resolved and is flagged rather than guessed

High-drain re-test after recharging (1.25A load)
- 296-year rechargeable AA battery durability retest (separate segment)
Eneloop 1.21 V (best of the group), Energizer (rechargeable) 0.83 V (running low), Amazon Basics black 0.98 V, Amazon Basics silver could not support the load at all, EBL 0.68 V (bad shape), Ikea Ladda 0.98 V, PowerEx and Duracell (rechargeable) no longer working properly, Varta/Active Energy (about 5 years old) both at 1.06 V

How it was tested
- device capacity drain test measuring runtime and mAh capacity in a constant-current tester
- voltage under a 1.25 amp high-drain load
- voltage performance in a sub-freezing (~0 degrees F) freezer
- 2-cell fan runtime test
- dead vs fully charged battery bounce height myth test (Duracell only, aside from the main brand comparison)
- separate 6-year daily-use durability retest of previously reviewed rechargeable AA batteries (distinct segment, see summary product entry)
“Looking at just performance and not the price, the blinks power which is a lithium cell came out on top with an average finish of 2.3... If one factors price into the equation, power out [Power Owl] moves from second place to first, in my opinion it's a great battery for a fair price and would definitely be my choice.”
