Equilibrium Heatsense Battery

The high-quality Heatsense battery can deliver up to ten sessions of effective heat & massage therapy. This equates to five hours of use. In extremely cold conditions, this can be reduced to eight sessions. To extend battery life, we recommend unplugging the battery from the cord after each use. After ten heat and massage sessions, we recommend charging the battery, this ensures that the Heatsense can deliver heat therapy at the required temperatures.  After ten uses, the heat may still be delivered, but it is unlikely that the temperature will still be optimal.
