Duration: 45 minutes
Steps: 6 Steps
Ready to give your Polar M400 a fresh start? This guide is here to walk you through the process of swapping out that tired battery for a new, lively one! Whether your battery is struggling from lack of charge, a splash in deep water, or just age, we’ve got your back. Remember, over time, wear and tear can take a toll. The Polar M400 features a rechargeable battery that can handle over 300 charges or last about two years before you notice a dip in performance. But keep in mind, how often you charge it can vary based on how you use it and the conditions it faces. Once you’ve successfully replaced that battery, don’t forget to dispose of the old one responsibly—check your local waste disposal rules and steer clear of tossing it in the regular trash. If you need help, you can always schedule a repair.
