36 V, 4.8 Ah Lithium-Ion battery. The AP 200 S is a high capacity battery that powers tools within the STIHL AP System. With an energy capacity of 187 Wh, the battery has an integrated LED charge indicator, clearly displaying as and when the battery needs charging. The AP 200 S has an improved cold start feature, meaning it calculates the voltage drop caused by cold temperatures and adjusts the battery current accordingly – meaning your tool receives maximum power from the battery and the battery is able to warm up efficiently. The AP 200 S battery comes equipped with the latest version of STIHL connected, allowing users to keep track of data such as total discharge time and the total number of charge cycles. This data is then made available in the STIHL Connected App, a fleet management tool capable of giving an insightful overview of all tools in your fleet. Durable and suitable for all weather conditions, the AP 200 S delivers the same long working times as the previous version and is the powerhouse behind the vast majority of AP System tools. This battery has a cold start feature, which protects the cells by warming them up in a controlled way before delivering full power and allows them to work down to -20° Celsius - delivering full power within as little as 2 minutes! AP System batteries feature intelligent battery management system - this clever technology gives a constant level of power whether the battery is 100% charged or 1% charged. Compatible with the AL 101, AL 301, AL 301-4 and AL 501 charger unit.
