This material quality at the best current cost, meets my needs. For now I do not know its reliability in use. This Day, the 07/05/2015, the 40V Lithium-Ion Battery 2Ah Greenworks Tools purchased on 24.07.2014 is declared defective by a flashing Red Charger. The battery test indicates the two lights lit on the four Greens. The battery is still under warranty. I bought a chainsaw Wireless Tools Greenworks and two batteries 40V 2Ah and one of them is faulty then what little served. I request replacement. After a second check by the Test Batteries, all lights are off. The control on the charger indicates the charging light is off. To date 14 May 2015, I still do not have the service response.
