r/AAMasterRace is a subreddit with 3k members. The most common kinds of discussions are solution requests and advice requests, and the community frequently discusses aa, batteries, charger, battery, and eneloop, and they frequently recommend/review battery.
Future-proof your life. If you use only AA batteries and you want 3 spares, you only need 3 spares. With 5 different batteries, you need 15 spares plus chargers. With AA you can carry it all in your pocket. AA-compatible devices can include AAA, AAAA, C, D, F, 14500, 18650, 21700, 26650, 32600, 32650, etc. Right to repair was first lost from tolerating proprietary batteries, pay per charge, and self-destruct explosions. To regain right to repair, you need the right to put in standard batteries.
