I do not recommend these batteries. These new batteries do not hold a charge for as long as the first batch; maybe 2 days. This is the second time I've bought these batteries. The first batch are about 2-3 years old and won't hold a charge at all.
Maybe I just received bad batteries, but I would rate them as junk. I recharged them and the same thing happened. Do not buy these batteries for a camera. They state that they will work better than regular batteries, but after I charged them they only took 5 or 6 pictures.
I am using a La Crosse BC-900 charger. I have bought several packs of these batteries and have seven batteries that have failed so far. They are good to start with but after a couple of charges some of them seem to fail.
This Sony battery was the last one. BTW, the manufacture's claim on the overall capacity was not even close to the measured capacity. He repeated the capacity test mutiple times and the clear winner was the Energizer NH15BP-4 and the Duracell came in second.
He conducted two tests on Duracell, Sony, Energizer and Lenmar: 1. Capacity test where randomly selected two batteries were fully charged and put on a regular flashlight until a complete discharge happened. My son's school science project this year was to test a set of rechargeable batteries.
The first test was inconclusive. It performed consistenly without being overcharged, but the overall capacity was not very good. Long term storage test where the batteries were fully charged and stored for two weeks before measuring the voltage.
2.
What's the deal with that. Even in a clock, they last about 3 days on a full charge. I bought these batteries when I bought the Sony charger. The charger is cool, the batteries are the worse I've ever had.
