Quick Diagnosis Guide

Most Heatsense battery problems stem from a connection, charging, or age issue. This guide walks you through each symptom, its likely cause, and the fix you can try before ordering a replacement.

Before You Start: Safety First

Always disconnect the Heatsense battery from the massage pad before inspecting or cleaning. Check the battery contacts for dirt or debris—this is the most common cause of intermittent power loss. If the battery has physical damage (cracks, bulges, or leaking), stop using it immediately and replace it with a new Equilibrium Heatsense Battery.

Symptom Diagnosis and Corrective Action

  • Battery won't charge: Likely cause: Loose connection at the charger port or the battery itself. Corrective action: Unplug the charger, inspect both ends for dirt or bent pins, and reconnect firmly. Try a different outlet. If it still won't charge, the battery may have reached end of life.
  • Massage pad loses power mid-session: Likely cause: Battery contacts are dirty or the battery is low. Corrective action: Clean the metal contacts on the battery and pad with a dry cloth. Fully charge the battery (3-4 hours). If the issue persists, the battery may need replacement. If cleaning and a full charge don't fix it, the battery likely needs replacing.
  • Battery drains quickly: Likely cause: Normal aging of lithium-ion cells after many charge cycles. Corrective action: Count the number of sessions you get per charge. If it's less than half of what you originally experienced, the battery capacity has degraded. Replace the battery to restore full runtime. A battery that holds less than half its original charge should be replaced.
