Materials
The wristband that comes with Alta HR is made of a flexible, durable elastomer material similar to that
used in many sports watches. It does not contain latex. Accessory wristbands are available in genuine
leather and stainless steel.
The clasp and housing on Alta HR are made of surgical-grade stainless steel. While all stainless steel
contains traces of nickel and can cause an allergic reaction in someone with nickel sensitivity, the amount
of nickel in all Fitbit products meets the European Union's stringent Nickel Directive.
Battery
Alta HR contains a rechargeable lithium-polymer battery.

SmartTrack data for two days, and summary totals for 30 days.

SmartTrack exercise, and sleep.
