Query: THEY LAST A FEW MONTHS...

They don't last that long, maybe 6 months. In fact after 3 or 4 months they don't hold a charge for very long. That eventually gets worse. I bought another pack to test them again, but if I get the same results, I will switch, most likely. I am one of those who almost always puts the phone back on the hook and I have heard that wears out batteries quicker, don't know.UPDATE: These last ones lasted only 2 months. I think I will go back to panasonic batteries. I keep buying these because they look pretty. But, they don't last. I'm not even sure 2 stars is low enough. I just changed it from 3. I tried, I really tried to give them a chance. I have a panasonic dect 6 phone I use them in and I have never had a problem with any other battery, just these duracell.UPDATE: I ordered these September 2011, because of the good reviews, so we'll see:GP RECYKO ALWAYS READY NiMH Rechargeable battery package: 8 AA 2100 mAh + 8 AAA 850 mAh
