Battery life in real climates: how we think about 2+ year targets

Why climate shows up in warranty conversations

Chemistry and self-discharge curves are temperature-dependent. A panel baking behind western glass is not the same asset as one in a breezeway, even if the SKU matches.

Operational factors

• Presses per day from cleaners vs. guests.
• Background polling intervals and firmware features enabled.
• Storage if units sit pre-installed between fit-out and lease start.

A practical stance

Pair manufacturer tables with your own pilot logging on a representative floor. Use that log when procurement asks for a single number—honesty ages better than optimism.

For authoritative electrical parameters, always defer to the current manual for the exact model revision you purchased.
