I've mostly used Procell batteries in my Schlage locks (BE469, FE599) for ~5 years. Over 5 years, average time between battery replacements for both locks is ~130 days.
The two times I used Costco Kirkland batteries, I got less than 90 days of use before the locks stopped working.
Are there better alkaline batteries than Procells?
Anyone tried Duracell Quantum? Supposedly they're the highest charge density alkaline battery.
Schlage doesn't recommend lithium batteries based on their discharge characteristics. Anyone with long-term experience using lithiums?
