Title: battery loses charge in 2 days
Review: I have 2 of these batteries. They both lose all their charge after one day. But model # 840639 19.2V UniSource(tm) 3-5 Hour Battery & Charger Kit is a battery [i have 2 of these also] which holds a charge for over 2 weeks! But i can not now find the 840639 for sale on the internet.
