how long does the rechargeable battery last?

I took my toothbrush on a four day trip across the country and it lasted. My old toothbrush would last more than two weeks, so I'm assuming that this one will be the same. I usually bring my charger anyway, well not for the 4 day trip.

Oh, I don't think the battery can be replaced...I don't see a way to open it. I had my previous chargable toothbrush for years and then I only replaced it because I wanted the latest model...not because it wore out! Although I did get to where it needed charging every 2 weeks...

It lasts for about a month using it twice daily for 2 minutes....the power does decline a little by the end of the month. So, if you want a strong charge all the time maybe charge it every 2-3 weeks?

It has been my experience that the battery lasts about 5 days with one person using it. If you are on a trip for a week, you can leave the charger at home. If longer, you need the charger.If your asking how long will the battery last before it has to be replaced, it can't. I had my old Sonicare for 10 years and the battery was still working.

Not long, mine usually goes about a month max. But been thinking about buying rechargeable batteries for it... Since it does get pricey. But the device does work wonderfully and does do as if says :)

I haven't timed the battery life but I use rechargeable batteries and have gone through multiple 2-hour practices on one charge.

It lasted over 2 hours straight off one charge. I don't know what kind of battery is in it but it is rechargeable :)

No. Its rechargeable. I've never had a problem with it. Lasts for about an hour or so at a time.

Hey Ken. This unit has an internal rechargeable battery. Its actually pretty long lasting too (from my experience).

It lasts a very long time! I fully charged overnight before first using it, and it kept a charge for well over 1 month. Used it 5-10 times for about 35minutes total recording time, before I recharged it.

For me, so far, it has been lasting just about 2-3 hours on a full charge. Almost 1 year of usage so I do keep it plugged in when not in use and definitely overnight.

I would estimate the rechargeable battery lasts about 5-10 minutes. With the crank the battery does not last that long. Maybe I got a bad rechargeable battery, which suggests bad quality control. At this point it is useless when the rechargeable batteries are in the unit. Regarding the 3 AAA battery it takes, I just checked the unit and they appear to be drained, but I am unsure of the power they had when I installed them. I believe someone else documented the fact that the battery drains when in alert/standby mode. Also, the unit is quite small. It is slightly bigger (but much deeper) than a smartphone. I hope to try another rechargeable battery before I toss the thing. I would estimate the rechargeable battery lasts about 5-10 minutes. With the crank the battery does not last that long.

Yes, it does have a rechargeable battery. Instructions suggest a 6 hour charge prior to initial use.

About an hour with regular batteries, 2+ hours with Energizer Lithium Max. The rechargeable batteries don't last long at all because they only start out at about 1.2 volts.

I am not sure exactly. But I will tell you the batteries drain really fast. I would recommend the rechargeable one.

Hi Robert, I don't remember exactly how long it took to charge, but I have had mine for over a year now and haven't had to recharge yet. I don't use it a lot, but it's ready when I need it.

It really varies depending on the use and also if the flash is being used. I would say it lasted me around 3 hours with flash usage. Recharging the battery is that quick and easy anyway.

I am not sure quite how long. I have left it off the charger for 3 days and used it quite abit and still had plenty of battery life left.

I have had this for about 4 years, and have never had to replace the battery. To answer your question, yes it is rechargeable.

There's a rechargable battery. It lasts a long time. I think it says 10 hours.
