I have a battery recharger that shows no indication when the batteries are fully charged. I'm supposed to assume they are fully charged after 8 hours.
If I leave the batteries to charge while I'm out during the day and there is a power cut while I'm out, they will not be fully charged after 8 hours, but I will not know this if the power is back on before I return.
Therefore it would be useful if I had a way to know whether there was a power cut while I was out.
The only method I can think of is to have a mains-powered alarm clock permanently on, so that a power cut will cause it to reset. But is there a better method?

Battery chargers that work like that are usually pretty low quality. They don't adapt their charge cycle to the battery type you have, so your batteries may not be fully charged after 8 hours. An intelligent charger measures your batteries and adapts its charge cycle. They also usually take less time to charge your batteries, and they indicate when charging has finished. So you could replace the charger instead of setting up a hack to monitor power cuts.

Set the time on an electric clock the uses household current
Most households today have microwave, this has a clock you can set. On nearly all of these the clock rolls back to 12:00 and flashes when the power goes out. Chances are you have one doing this right now. Set it to the correct time, if the time is still correct next time you look at it, their has not been a power outage.
VCR players used to have the same thing, but not many people have them any more.
Lastly just buy a small electric clock, get one with a radio to use in the kitchen.

Some clocks will flash 12:00 when the power returns and then keep time normally, but still flash the time. From this, you get an added benefit of knowing how long ago the power came back on, although you can't tell how long it was out for.

If you have a desktop computer, just leave it working when getting out of the house.
Then when you get back home, several options:
- Computer still on, no reset was done: no power cut.
- Computer is turned off: there was a power cut.
- Computer still on, but you notice it was reset:
- If planned reset, e.g. due to Windows Update, you can't know if there was power cut.
- If unplanned reset, most likely due to a very short power cut.

Battery chargers that work like that are usually pretty low quality. They don't adapt their charge cycle to the battery type you have, so your batteries may not be fully charged after 8 hours. An intelligent charger measures your batteries and adapts its charge cycle. They also usually take less time to charge your batteries, and they indicate when charging has finished. So you could replace the charger instead of setting up a hack to monitor power cuts.

@Hobbes Good point, but I wonder how advanced rechargers would cope with a power cut.

I'm assuming getting a better battery charger is not an option?
