How long does the battery hold the charge when switched off?

Weeks for sure, but the charge wears off quickly. I think there are better batteries & chargers out there. I've been thinking of replacing them with the most premium ones I can find, and getting a high quality charger...................

the item requires 18650 batteries, after the batteries is fully charged, it could run about 1 hour for the Strong Brightness model.

Cannot truly say, I was using it 5 - 8 hours daily and it still had battery. If I had to be over night without a charger turn it off and start the next day, it still ran but limited.

I can't answer exactly, because I use it for quick pick ups. I actually have never had it run out of a charge but occasionally I just plug it in.

While I am not certain of actual hours, mine seems to hold its charge for days when on the shelf. But it is probably different if you are cycling it on and off.

I have charged the battery maybe 4 times now. I would say it lasts for a good 6-8 hours of on and being used time.

Standby battery is really great, *IF* you turn it off after every use. I once charged it for a one-hour presentation, turned it off and left in my bag for a whole month and was able to use it for another one-hour long presentation with no issues. That's pretty amazing.Turning it off is quite easy, just push and hold the on/off button until you see the blue light blinking really fast and then let go. You'll see the blue light pause and then fade slowly, that's how you know it's turned off.

The battery lasts around 4-8 hours on full charge so you can leave it on till it dies, I don't believe it goes to sleep if inactive.

Although I never timmed the charging of the Battery, I do know it doen't take all night. I would guess about 5 or 6 hours

If I remember correctly, it should just turn off. I used it for a dead but relatively new battery and it worked perfectly. Just keep in mind that it took three days or so to fully charge.

I'm not sure. I keep it plugged in. Sorry I can't be much help regarding the battery life.

probably about 3 plus hours -we use it for travel so it is usually being plugged in every night or during use. Never have had a problem with too little battery.

It holds a charge quite awhile. It is at least a week between uses maybe longer.

I haven't timed it but, I would say hours. It blinks on and off when the battery gets low so you aren't surprised when it goes off

It probably took about two hours for the battery to fully charge. I have used it off-and-on for maybe an hour a night for two weeks. The battery is still going strong. The unit goes to sleep after 15 minutes of non-use to save battery. Hope that helps.

Well like every battery it depends on how u use it,since I got it which I think was January I've used it every now an then without having to charge ,I would recommend leaving it switched to off when not using it

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.
