Battery Lasts for Years: Equipped with a powerful built-in battery (CR14250 with 800mAh capacity) providing continuous performance for up to approximately two years. Extremely Small Size: Dimensions do not exceed 42.5*24 mm. Strong Magnetic Mounting: High-adhesion base ensures it stays firmly attached like a rock to metal surfaces and under vehicles.
