FAQ about our Polar GPS Sport Watch M400 Smartwatch battery and charger:
Compatible replacement battery vs. OEM originals:
Our Smartwatch batteries are always lower in price and will meet or exceed the
performance of the original Polar GPS Sport Watch M400 Smartwatch battery. Batteries can sometimes
even contain identical battery cells
as the OEM original did, but lacking the brand name, can be offered at a discount prices.
Our GPS Sport Watch M400 battery is covered by a 3 year limited warranty, far longer than the
warranty on your original Polar GPS Sport Watch M400 Smartwatch battery.
