Review on 5.0Ah Replacement Battery For Worx 20V PowerShare Tools - Compatible With WA3575, WA3520 & More! by Micael Casillas

I recently bought a 3 piece set of Worx yard tools, Blower, String Trimmer and hedge trimmer. Compared to the batteries provided these batteries last over 3 times longer in the same tool. My only complaint is that they take a really long time to charge using the standard charger provided with the tools. Apparently there is a quick charger that I need to purchase. UPDATE - after 6 months, 1 battery still works okay and the other is useless. Second battery will charge and then start to run and then die. Maybe use twice a month.
