STIHL batteries can be charged with either the AL 101 standard charger or the AL 300 or AL 500 quick charger. Each charger features a different charging capacity (Watt). The quick chargers have active cooling for even faster charging. In addition, the AL 500 features a housing base for wall mounting. When used for prolonged periods - by professional gardeners, for example - it is advisable to use two batteries to save time.
