The scientific answer:The battery is Ni-MH, rated for 750mAh at 2.4v. VTech advertises that this battery will last 18 hours, but I think that is overly optimistic. Power usage will depend on how much sound is being played over the speaker, user interaction, backlight usage, etc. There are no published amperage values for unit consumption.Real world answer:It seems that about 5-6 hours is a very conservative answer. I've used it for two hours and the battery meter is still showing full charge. NiMH is known for having consistent voltage and then plummeting at the end, though.

It depends on how loud the girls are during the night. The other night they slept through the night, which means that the unit didn't get much use. If they are fussing, etc. a lot then maybe it'll be less, but ours worked 8 hours during the night, then 4 hours during the day for naps, and the battery still has 2 bars.

Not very long, We've gone through 2 of these things thinking maybe the battery was bad in one, but to no avail, both seem equally bad. There seems to be no indication that the battery is fully charged, the charging light stays red from what I can tell, I've charged it for 12+ hrs, take it off and almost immediately the battery percentage drops to 2 bars. All in all the battery lasts about 4 hrs in a silent house. If your child cry's a lot I'd bet you get less.

Depends how long you have been using it. When we first bought it it lasted 8-9 hrs. After about two months of use (not usually longer than a few hours unplugged) it has dropped to around 5 hours.

On a full charge, the parent unit can last a good 10 hours. We have frequently left it unplugged overnight without realizing it and it was still charged in the morning when we found it. I have also found that the less your depend on the battery, the longer your charge will last when you do need it.

These are not easy questions to answer definitively since it runs automatically and I have never just run it out of power to see how ling that takes. Having said that, my estimate is about three hours run time. I have my unit run every day and it usually runs for over an hour with no troubles. It returns to the charging unit on its own. I have often run it for an additional 60-90 minutes within a couple of hours of a previous usage with no problems. So it seems to charge quickly.

Once the battery is fully charged, this unit has a standby power consumption of 5.0 watts as measured by me. As well, I plugged a 100-watt incandescent bulb into it and let the UPS fully discharge, taking 67 minutes. While charging a fully discharged battery, this unit pulls 21 watts; as it completes its charge it drops to 5 watts.

Hey Derrick... I charged it when I received it on April 30. I use it on average 2-3 hours per evening. I use the back light function every 30 minutes or so and the unit is in standby during the 2-3 hours of use. I turn the unit off each evening. I have not yet had to charge the battery.

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.

When new, the battery lasted 45 to 60 minutes after a full charge. The second summer season, a full charge resulted in only 30 to 45 minutes. This summer will be the third season, and I hope there isn't another drop.

We usually charge it over night after each use to ensure a full charge for the next time. But after 6 to 8 hours it's good to go. I like to let them run it completely down and then charge it just so the battery doesn't get a memory.

while operating - at least 6 hours. I think mine died during the 7-8 hours after a full charge. I leave it in my car and the batteries remain charged until I actually use it and I'd say it keeps its charge for awhile, on a monthly basis. Not too sure about annually.

It seems to shut off when full charge is reached, don't know the answer too second question.

Your current usage will determine how long the battery will last.If your running it to full capacity,then it mightn't last too long.

I've never had the baby unit on batteries. The parent unit has lasted at least 18 hours on a full charge off of a pair of 2000 mAH rechargeable AA batteries.

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

Haven't really timed it out from drained to full charge, but my best guess would be 30 minutes.... :-) hope this helps God Bless

Yes, however; the battery life is not nearly as long-lasting as the parent unit.

You have a lead acid sealed battery, where it is best not to discharge it more than half forgetivity, before recharging it fully. Usally it will last about an hour in solid surface or about 15 minutes witha single kid. With 2 kids about half fully discharged.

I haven't tested the life span. I plug it in at night to be charged for the next day.

I should add to my previous response that the battery life on a full charge is at least 8 hours.
