Which maintenance item should be replaced every 2 years based on usage?

• A. Building Code Requirements
• B. Curved Installation
• C. Battery Maintenance
• D. Remote Parking Feature

Answer: (C)

Batteries wear out with usage because the chemical reactions inside them degrade as they are charged and discharged. In escalator and moving walk systems, the backup or control power relies on batteries, so their capacity drops over time and with cycling. Because of that, a scheduled replacement based on how much the battery is used helps maintain reliable operation, making a two-year interval a sensible maintenance target for this item. The other options aren’t wear items tied to usage: building code requirements are regulatory updates, curved installation is a design feature, and a remote parking feature is an optional capability, not something that degrades with use on a fixed schedule.
