The manual says that the intitial charge should be atleast 21 hours and then it says to recharge for 21 hours when needed. Will a shorter time work?

If you don't fully charge the battery the first time, is can develop a memory and you will never get the "full use" of it. ALWAYS charge anything with a rechargeable battery at least 12-24 hours before use (cell phones, cordless phones, GPS, etc) it will just ensure you don't need a new battery for years.

bought for my daughter.i fully charged it 21 hrs and brought to her.she started doing her steps and after 4 steps she said get this thing out of here.i felt the same way.what a waste.im goen to try their 20 volt lithium ion for a little more money.it will stay at FULL POWER till it dies.and you don't have to play that 21 hr game to run it for 10 min max.lithium battery can be charged for 2 hrs or the max without hurting the memory at all.

I think it may be important to make sure it is fully charged initially, but a shorter charge will work, but it may not run as long. I keep mine plugged in all the time, so it is fully charged anytime I need it. I've had it about 3 years and have never had a problem.

No idea. Even after we gave it a full charge, the suction was inadequate. We returned it

We just purchased and unboxed this item. The charging instructions now read to charge for 9 hours (February 2015). It continues to recommend five or more fully charge then fully discharge for optimal battery life.

Yes it will.. but the problem most people have with this product is with the charger and they don't even realize it. The battery is good. Many of the chargers came from the manufacturer defective, so with the warranty, if you run into charging problems, you should get a replacement. I had to do this, and it was an easy process. The new charger has been working in harmony with the battery for over two years now, and only needs a couple hours to charge back up fully.

The biggest caveat is to pay attention to the directions. 21 hours, completely deplete the battery then put it on for another 21 hours. Have to do this 5 times to complete the batteries fully charged memory. I can guarantee you the majority of the complaints are people who didn't take the time to read the directions and/or follow the directions. After those 5 charges up to you what you do. I'm a fan of the old battery technology of retaining batteries memory by ALWAYS completely depleting a battery before I place it back on the charger. These new batteries don't require it, but my method has yet to fail me. :) The biggest caveat is to pay attention to the directions. 21 hours, completely deplete the battery then put it on for another 21 hours.

I use my Black and Decker almost every single day in my motorhome. I simply leave it plugged in, in an inconspicuous location i between uses. I have no idea how long it would take to charge if the battery completely ran down; I've never had that happen. I tend to use it in 5-10-minute spurts and it's been fantastic. Hope this helps.

I keep mine plugged in all the time also and have had it since Dec 2012 no problems it is so handy for spills or crumbs on a table . I used it several times a week . It is a supplement not a only vacuum . I even take it out to the car for touch ups and it is so nice to just go around the garage and dump it out . No bags to buy .

I charge it when it's almost dead, and then it works for at least fifteen minutes the next time I vacuum. If I only use it for a couple of minutes, I don't recharge. Hope this helps.

between 3 to 4 hours but I was never in a position when I needed it really soon so it might charge sooner then I originally stated

It took a few hours to charge the first time and slightly over an hour to recharge, depending on how depleted the battery was at the time of recharge. This unit takes no longer than any other charger and battery.

A good question, Ann. The manual only says that after the first time you charge it, it will need shorter charging times. The first time I charged mine, I just left it plugged it for several hours, checked and the green light indicated a full charge. The SECOND time I recharged, however, the light went green after about 2 hours, so I attached it to the trimmer for use, and the LED indicator said it was still one level short of a full charge. So why did the green light come on? If you could just leave it charging overnight, you could be sure it's fully charged, but it has a warning light (orange) for when the battery is too hot and should be removed from the charger. So I recommend charging during the day and checking it periodically to see when it's green.

no, it does not take 24 hrs. Yes you can recharge at will. Most all devices like this the manufacturer want a deep first charge. one other suggestion. I had 2 of these. one sank. On the remaining unit, I cut down a Styrofoam noodle to fit between the handles, ran nylon rope thru the hole and tied the ends to the handles for extra floatation. Make sure that you seal the battery cover like the owners manual states. I think that is why one sank.

If you just got it, you may need to charge it longer than that for the first initial charge. I let mine charge for about 12 hours or more. Not the goal, I just didn't need it right then and I forgot about it. It worked fine when I used it about 3 weeks later after being in my purse all that time. And it fully charged my cell that was at 10%. Be sure to recharge it after use though. The light indicator should work also......And like the others replied, be sure to hold the button once you connect it to what you are charging.

It is supposed to go 2 weeks on one charge but as long as I am at home I keep the charging base (separate but comes with the brush) plugged in and set my brush in it every night. I really haven't tested out how long a charge will last. Do give the initial charge 24 hours, or until the light stays on steadily.

Yes. I find the recharge takes about 2.5 to 3 hours. Buy two batteries and keep one changed for backup.

It depends on the charge and how much current is pushed through the battery. Faster charging heats the battery, which is not good for it, so you have to balance speed vs lifetime. I use a smart charger (a small LaCrosse) and keep it at the lowest setting, and fully discharged batteries take about 8 hours to charge. I put them in before work and they are ready when I get back.

After the initial 24 hour charge, we recommend using the product unplugged until the battery is low and then plugging it in for 20 hours to recharge. For warranty assistance, please contact customer service directly. You can send us an email through our website at www.foodsaver.com/contactus.

Yes this is to be expected even with the four hour charge time the internal battery only last 20 minutes. The best thing i found to do is rip out the internal battery pack and use a triple A battery holder in its place with 3 rechargeable triple A battery's. look-up on YouTube for help.

The initial charging time is 24 hours. Let it charge for 24 hours before you use it.

Now that I have used it for awhile I can answer that it can take a bit over 24 hours to recharge when you have received the low battery warning. I let mine charge overnight, use it in the morning and then put it back on the charger. By evening it is fully charged.

Let it charge for 8 to 12 hours. It charges slow at first this helps the battery live longer. you want long term battery health let it charge 100 percent. Then it should be good. I love mine!

It depends on how much battery life is left. For me, it usually took about 1 to 2 hours to recharge full. I hope this helps.

Yes, the charge is supposed to last for 15 hours. I find that it lasts for about 6-7 hours.
