How long does one charge last?

I keep my charger plugged in all the time. I use it for depression light therapy so need it for 1.5 hours daily. It can keep up if I keep it plugged in but I do have two and usually alternate days.

Not very long but long enough for a session, I just keep mine plugged in all the time when I'm not wearing it

About the charge length & battery life: --I use my light visor most mornings for 30-60 minutes on the brighter setting. In the dead of cloudy winter weather, sometimes I'll use it up to 90 minutes. The light stays strong during all of that time. --If I forget to charge it overnight after a morning's use, then the next morning it will start to dim as I'm wearing it, so I charge it nightly. --Also, if it's fully charged but I don't use it for 3 or 4 days, I find that the charge has drained off. --I try not to keep it on the charger longer than overnight. --I've had & used my light visor for 3 years, 4 months now; still works great after much use, with no deterioration of battery or light quality.

Definitely around that amount. I usually charge around once a week and it charges in about 1 to 2 hours.

Of course that depends on how often and how long you use it. With my average use, I charge it about every couple weeks.

Manufaf said this- IMPORTANT: Do not charge for more than 8 hours at a time. Overcharging can damage the unit andvoid the warranty. Under normal use the unit will need to be recharged for 8 hours every 60 days.

I have not actually timed it do be certain, but I walk with them and figure they stay charged for a minimum of 2 hours. Normally me walks are 30 minutes a day and I only normally charge them once a week.

I would guess several hours, I didn't keep it in constantly after a charge, but using it 20-50 minutes at a time a few times a week, it lasted over a month for me.

I would say it depends how often they are actively running. In my experience, using them in the same product as a disposable, I get 24 hours per charge or 3-4 times longer than that with a disposable. If you know how long a disposable lasts in your sensor, you could make a guess that this would last for your purposes.

I have- but have no idea what that means. It hasn't been a problem for me, but I still have no idea how long to charge it for.

I initially charged my battery once, for a full day. After that a normal charge takes 3-4 hours.

Where did you hear that? Of course not. I use mine daily and it usually lasts for 2-3 days based on my reading, web surfing and emailing activity. I let the battery completely run down after I first charged it and it lasted almost 11 hours. On average I get at least 10 hours of active use on it, but I usually charge it every three days.

Really I don't know. I usually charge it around 8 hours and after that, I use it. But I don't like at all.

The charge has been lasting about 20 to 30 minutes. Initial charge was 6 hours and charging after use has been taking anywhere from 2 to 3 hours.

About half a day. However mine only charged once and then failed completely.

I get about 8 to 10 hours on a charge. I also have a Mini usb charger installed on the bike so when ever i have long ride and I stop to take a break I plug it in to charge.
