SBD, the sad end of many a battery.

You can keep charging and draining it and see if it comes back.

I think it's the battery and not the camera.

"It's not you. It's me," said the battery to the camera.

Your complaint prompted me to go look at your topic list.

Your battery is like a 100 year old person, they both start the day with energy but it does not last long.
ie. your battery is holding a charge and it will read 100%, but in reality it is very close to the end of it's life and should be replaced.

Batteries in devices when not used will drain.

Another test would be to charge the battery and see if it works.

Thanks. Doing that now.

Bingo.

The last reading was in memory.

Batteries discharge slowly over time, and some functions always are a drain such as a clock.

I'm sure you're right about the 100% reading being in memory. I am making a test noe.

You don't say whether the battery was inside the body during non-operation. Batteries will drain over time so it's best to take them out if the camera is not going to be used for awhile. Then charge the battery prior to use; remember to set up date and time if needed.

It was in the camera. I think it's what one UHHer said. The camera remembered the 100% batt reading from the last time it was used. I didn't check the batt condition until it died. Fortunately I was not an important assignment.Good suggestion to remove the batt when camera not used for a while.

Batteries require a regular pattern of charge/discharge cycles to remain chemically active. Modern batteries are better then before but still need to be used regularly. Thank Ghod NiCads are out of photo equipment nowadays.

NiMH and Lithium Batteries need frequent use cycling between 20% and 80% charge to prolong longevity. If you seldom use them, they build up internal resistance and die. They will show full voltage, but they’re incapable of delivering full wattage needed to power the device.

Buy new batteries when that happens.

It did charge. Must have been an anomaly with the camera. After all, it's 11 years old.

If it works - don't fix it!

We're sorry, we don't all have your supreme knowledge. Some of us, probably 99%, ask questions when we don't know / understand something. That's how we learn. I very rarely hear a stupid question, but I've just heard a ridiculously stupid answer.
