Thank you for the battery but it is only lasting about an hour when it is not plugged in. I have tested it 3 times and it will not build up.

Unfortunately I cannot help you. This was for my grandson's laptop and I believe the battery did help as I didn't hear him complaining. But the laptop is crashing. Sorry.

The battery has run 3 hours with no problem. Probably will go longer with a full charge. I stopped before the battery did. This is an excellent tool.

I have been happy with it. Instead of about 2 hours of unplugged life, the battery gives 3 hours. The physical size is the same.

I like the unit so much, I just bought some for my kids. But the battery is it's weakest point. It lasts maybe two hours. I plug mine into my computer or an AC charger when I am using it.

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.

Unplug it, let it drain conpletely. The recharge it. Make sure it is charging and charge it no less than 6 hours. I found the battery lasts a long time but needs about 30% to power up. Charging for 3 hours wasn't wasn't enough. If it doesn't work ten sed it back . It needs a good but of power to start

The battery died and it won't recharge. I only used it a few times but not for more than a few hours.

Is it possible the battery is not charged? The instructions suggest it is necessary to discharge fully then recharge. It may be it came discharged, and must be on charge to be recognized, I bought an inexpensive battery and it lasted about three days, then began indicating it should be replaced. The only other possibility would be an incorrect battery? Best regards, Sammy

It actually has it's own built in battery. It lasts about 5-6 hours, which isn't too shabby.

Although I have not timed it, I used the cutter for one half hour or so and and I actually began tiring out. Then, I pressed a button on the battery pack and it indicated that only half of the initial charge had been used. For me, it lasts plenty long enough.

I'm not typical...I use my laptop only occasionally and it stays plugged in most of the time. However, I did test the battery when it arrived and I got about 4 hours out it with light usage.

One more little helpful hint though...don't leave it ON or it WILL go dead a lot quicker! Found that I had done that last night when I had a dead battery and was like, no big deal...I have my handy jumper...which I then found I had left on and was dead! My bad! :P

You should at least be able to power up after 2 hours. I've always left mine plugged in overnite but they've been known to have defective batteries.

It was charged up fairly quickly, within couple hours. Before I got this one, I bought a battery from Radio Shack, with a slightly different current rating, and that one never charged up, just like what you said! You may want to check the current and other spec, to make sure everything is compatible.

Try giving the battery a full charge for 24 hrs see what happens thank u...

I have no issues with this battery. I run my laptop for hours at a time typically, so I keep it plugged in. If you were to run as little as possible, I'd say it would probably last an hour or two.

A good brand regular battery seems to last several hours. Am pretty sure you can add music to it fromiTunes. I'm very pleased with mine and have gotten hours of pleasure from it and found it simple touse even though I am up there in age (almost 70).
