Battery Life & Charging

Quick Tip: We recommend charging SmartSole daily, like a smartphone.

Charging your GPS SmartSole® is very easy with our wireless charging pad! Simply place it on the charging pad included with your order. Align the insole so the target symbol on the bottom of the insole is on the center of the charging pad; adjust until the status light is solid blue.

It takes two to four hours to fully charge your GPS SmartSole® which will last between 2-4 days on a single charge. Individual, actual use may vary between 18 – 96 hours per charge. Continuous motion, long drives, and areas of poor  connectivity may drain the battery more rapidly.


Proper Care, Handling and Storage Guide Lines for Lithium Batteries:

Quick Tip: Rechargeable batteries have a limited number of charge cycles and may eventually lose capacity.

Like all Lithium batteries, your GPS tracker’s Lithium battery has a limited number of cycles and requires proper care, handling and storage. Please note that Lithium batteries should not be stored completely drained or completely full – both storage methods reduce the battery’s lifespan. For long term storage, it is strongly recommended to turn off the GPS SmartSole®, Take-Along Tracker and any other product using Lithium-polymer batteries at around 80% charge. In addition, we recommend fully depleting and then recharging your GPS product at least once every month, which helps to maintain and monitor battery performance. We test all product before shipping (usually on the same day), and we recommend distributors and resellers to test again upon receiving, before putting the product into storage mode, then test once more before shipping to their final destination.

If a battery has been unused or not charged for more than 6 months, it is very possible that the battery will not be able to be recharged and therefore will need to be replaced. Although it’s best to fully charge a battery before use, prior to storage of lithium-ion batteries it’s harmful to fully discharge them. The best battery manufacturers store lithium batteries at around 60 degrees and at a 40% charge level. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. Routinely check the battery’s charge status. If you do not follow the instructions, and the battery has no charge remaining when you check it, consider it to be damaged. Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.

With proper storage and use, the typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first.
