When to reach for lithium
Lithium lasts far longer under sustained or high drain and keeps working in the cold — while alkaline is the ideal, economical choice for everyday low-drain devices.
Alkaline (MAX / MAX PLUS)
Ideal and economical for everyday, low-drain devices — remotes, clocks, toys, torches. MAX PLUS steps up for higher-drain gear like controllers and headsets, lasting noticeably longer than standard alkaline.
Ultimate Lithium
The world's longest-lasting AA/AAA. Delivers far more power under sustained or high drain, keeps working from −40°C to 60°C, is about 30% lighter, and holds charge for up to 25 years in storage.
