Review on Experience Unmatched Power and Endurance with UltraLast Green High Power/Capacity NiMH 4-Pack AA by Anita Davis

I bought a heavy duty pack from Revain and two other heavy duty packs from Walmart. Only one battery from these kits worked. The rest were short circuited on arrival. The packaging said they could be charged with any NiMH charger so I tried 3 different brands of NiMH chargers I have at home and they all flashed red when I first plugged them in. Very sure the batteries were shorted on arrival. Conclusion: do not buy powerful. I also bought the regular green Ultra Last AAA AAAs but they were amazing so I think the regular AAs might work better as recommended by one of the customers in his review.
