How long does the battery last on a full charge?

I didn't get a chance to find out because it didn't work properly to begin with, and so I returned it. It took maybe 4 or 5 hours to charge completely which is what your suppoosed to do before you use it for the first time.

If you use the battery that comes with it, about 4-5 hours for a full charge.

About two hours, then I charge after each use to make sure it doesn't fail during my swim. There's nothing to indicate a full charge, unfortunately.

No way to check battery life from what I can tell, but there is an audio indicator that lets you know when it is close to running out. Never timed it to know the exact duration, but from being completely dead to full charge, I think it takes about 2 hours.

Mine had a partial charge so I can't be sure, but I think about 4 hrs to fully charge.

The battery lasts around 3-4 hours fully charged. I found it very useful to keep it plugged in while using it at home.

Average Battery Life is about 4 hours. The product description, (That MOST people seem to ignore), is "UP TO 5 Hours." 5 Hour Battery Life IS NOT Guaranteed. On a FULL charge, battery lasts 4 to 4.5 hours.

It's ridiculously long. I've had this for over 6 months now and it still shows it has a full charge. I expect I'll get about a year without changing it at this rate. Buy it.

I have left mine for a month at a time and it has held a full charge, no problems!

No actually the battery life is pretty good. When it's fully charged I would use it for about 3-4 hours

it depends on the charge of the battery, but usually a fully charge will last 2 hours.

From all the way dead about 6 to 8 hours for a full charge. When it is charging there is a red led, and when it is fully charged it turns blue. It works great!

When I first received mine, it took about 20 minutes to an hour to get a full charge. By the time I finally just threw it out (less than a year later) I would leave it plugged in all day and get about 30 seconds of use.

No idea, fully charged I can use for 5 hrs or so before plugging in, hope that helps
