The STIHL AK 20 & AL 101 Starter Set – AK System is the ideal power package for STIHL AK System tools. Including a 36V AK 20 lithium-ion battery and AL 101 charger, this complete starter set delivers reliable cordless performance, intelligent battery management and convenient charging for a wide range of garden maintenance tasks.

The STIHL AK 20 & AL 101 Starter Set – AK System provides everything you need to power your STIHL AK System tools straight out of the box.

Perfect for homeowners and gardening enthusiasts, this practical starter kit combines the versatile AK 20 battery with the dependable AL 101 charger, giving you a complete cordless power solution for maintaining your garden with confidence.

The AK 20 is a powerful 36V lithium-ion battery featuring a 4.0Ah capacity and 144Wh energy capacity, offering an excellent balance of runtime, performance and weight. Designed for regular garden maintenance, it provides dependable power for demanding tasks such as grass cutting, hedge trimming, pruning and general garden care.

Advanced battery electronics ensure a constant level of performance throughout the entire discharge cycle. Unlike some battery systems where power decreases as the battery drains, the AK 20 maintains strong and consistent output whether fully charged or nearly empty.

For year-round reliability, the battery also features an innovative cold start function. This system gently warms the battery cells before operation, allowing the battery to work effectively in temperatures down to -20°C while protecting cell performance and longevity.

An integrated LED charge indicator enables users to quickly check the remaining battery charge level at any time, helping with job planning and reducing unexpected interruptions.

Included in the set is the STIHL AL 101 Charger, a robust 230V charger compatible with both STIHL AK System and AP System batteries. The charger includes a clear LED charging status display and features passive battery cooling to help maintain battery health during charging.

For added convenience, the AL 101 includes a Velcro cable strap for tidy storage and can be easily wall mounted in a workshop, shed or garage.

Whether you’re purchasing your first STIHL AK System tool or expanding your existing cordless collection, the AK 20 Battery & AL 101 Charger Starter Set provides reliable power, convenient charging and trusted STIHL performance.
