I have taken well over a 1,000 photos with my Sony A100. I fully charged the battery a week ago and over the last few days I have taken fewer than 100 photos. The camera shows a full charge remaining. But I thought I would 'top up' the battery so as to have a full charge for tomorrow. So far the battery has been charging for 12 hours and the light on the charger remains on. The Li-ion battery is a genuine Sony, model NP-FM55H. The charger is Sony BC-VM10. Is such a long charging time usual? Is the battery defective? (It seems to work fine.) Is the charger defective? Should it charge the battery in less time? Or, am I just too impatient?

SONY has made the worse battery in the world, I have SONY cameras, notebook computers, AA rechargeable batteries.... All of them have defected after the first or few uses. So go to ebay to buy two more after market batteries. Do Not buy any battery has SONY name on it.

While I do agree that sony batteries have problems (Look at Dell and Apple Notebooks) if the battery were dead it wouldn't be showing a full charge. It would either be dead or blowing up in your camera :sad:

Not a bad idea to pick up a spare. I have 3 and rotate through them. Always carry at least one extra with me. 7D goes through them much faster than the 5D or A100.

The SONY batteries that I have are not totally dead, most of them are still accepting full charge under normal time, but the discharge time is very short, for example the battery for my VAIO notebook could last approx. 2.5 hours under normal use when it was brand new, but down to 15 minutes after it was 3 months old. All SONY batteries that I owned have the same problem.

"All SONY batteries that I owned have the same problem."

I have no reason to doubt your experience; mine is the opposite with I-Lithiums in my Sony Mini-DV camcorder. The batteries seem to last forever in the bag, and to date I see no issue with premature discharge.

I could be wrong but I don't think you were being acused of trying to fool anyone. I took thereference to "Fool me once; shame on you, fool me twice; shame on me!", to infer that you keep buying Sony batteries despite having problems with every Sony battery you have owned. Of course buying after market party batteries is not always easy or possible and some third party batteries are junk.

By the way, I have experianced problems with rechargeable batteries on one of my camcorders with both OEM and aftermarket. The battery in my Acer notebook did not last very long either.

The KM batteries I have work very well as do the Maxcell equivalent at least thus far.

I meant: If you don't like Sony batteries, stop using them.
