Is is best to keep on charger or to only charge when "Dead"? Mine is only two months old, but will only do half of the kitchen. The next day, it has "recovered", and acts like it is fully charged.. for another 90 seconds, then dies. I have been told not to charge batteries until they are "dead", and even with a full charge, it lasts less than two minutes. Is is best to keep on charger or to only charge when "Dead"?

I had an older version of this stick vacuum that was amazing. I decided to "upgrade" to this version and I can't get the battery to hold a charge to save my life. I even ordered another battery and that didn't hold a charge, either. Mine also runs for about 90 seconds and then dies.

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.

I keep the charger in the charger base when I'm not using the vacuum. The charger will die quickly when not being charged. Perhaps the instructions say something.

I don't think that it matters to the battery. The battery is low-quality regardless and will not hold a charge. I personally just put the vacuum on the charger before I will need it; but if you are the type of person who needs to use the vacuum without planning in advance, you should leave it on the charger. The disadvantage with this (and with low-quality batteries that don't hold a charge) is that you are paying for the electricity when the battery is being charged all the time.

We have done it both ways with success, but most often keep just the battery plugged in so there's no chance of it being run down when we need it. So far, that has not been a problem.

It's suppose to be plug charging when you are not using it so when you need it it's fully charge, but the battery don't hold charge anyway so it doesn't matter. I throw away mine, it's not worth it.

perhaps you got a dud then. I keep mine on the charger all the time. this thing picked up all the dead pine needles from my xmas tree far better than my $400 Oreck vaccuum. It's unbelievably good.

I've had this for over 6 months and I've always kept it on the charger when its not being used. I use it daily and haven't had any problems with the battery.

I am not really sure, i have a total of 3 batteries, so when/if one goes dead, i just pop it in the charger and it stays till i need it again. My android phone takes a while to charge, even on its own w/o any apps running. My guess it takes about 3 hours from completely dead to charge.

I learned that sometimes running a discharge cycle first then let the charger do it's job works really well but if the batteries are there for hours, there most be something wrong, are the batteries new or are they over a year old? Some old batteries will never charge. There's a chance also that the charger may be defective.

I just charge it for the first time a few days ago so it last two almost three weeks. It was a long time, I was surprised. I put the charger in a drawer because it does last so long.

Something must be wrong with your charger. Mine works fine. After use I repace my unit in the charger and the Orange light will turn to green (indicating a full charge )after one or two hours. Ready for use again. I have had no problems with my unit and use it for 30 to 40 minutes every other day ..Kendra

Thank you Guys for all your answers. Just want to ask one more question. When is the time to recharge it to prolong its lifespan? When it is completely dead, when light is red when pressing that little button or should I rely on camera battery status?

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.

it's always best to charge any battery at first use. I have trouble with my charge light also. The flashlight work great for the first few months, now it doesn't seem to hold a charge for very long at all.

From my experience I wouldn't attempt to go over an hour. I had three batteries charged and ready at all times. When one would get low I would change it and put the used one on the charger. If you are shooting continuously go AC if you can't use AC keep an eye on your battery level. I hope this is helpful.

Its best to use a smart charger like EBL; its always best to know how well each cell is charging or how bad by how long its taking; I had the energizer dumb slow charger where if it stop charging the batteries would seem to discharge; I had a fast digital charger but its so picky on which two cells to charge; with EBL I can be smart about whats going on with my batteries and determine which are so bad to toss away plus if it stops charging it keeps it trickled to prevent discharging

Sometimes "New" batteries have sat on shelves for so long they have discharged completely. I advise getting Rechargeable batteries with a charger, remove and install when fully charged light indicates full charge. Otherwise, return the timer for a new one, could be a lemon, it happens. My cheap-o batteries from the dollar store barely lasted a month, but the rechargeables are still running after 3 months.

I don' know. I believe letting/not letting them discharge is NOT an issue with this type (they don't have the ghost charge problems other models do) . I recharge mine when they still have life left and haven't noticed a shortened lifespan, but haven't done a formal experiment.

Mine lasted exactly 2 months. I left the charger plugged in when not home. I am unsure whether this causes is to burn out faster or not.

I will try to answer y our question- I leave it on the charger several hours and then it lasts for daysafter I use it again.I usually just put it on the charger at night and when I wake in the morning and use it. It just seemseasier to to it at night.

I am sorry, but I do not know the answer to this question. I normally put them on the charger and put other batteries in the unit the batteries were removed from. I put the discharged batteries in my charger, two or four at a time, plug it in and go about my activities. When they are charged the charger light turns off and I remove the charged batteries when I notice they are charged. Usually it will be the next morning or in the evening. It is not uncommon for batteries to be in the charger for eight to 12 hours. Tom Kerr

Basically an old wive's tale at this point. Modern chargers mostly detect when a battery is full and stop charging (or drop back to just trickle charging). I wouldn't worry about it unless a manual for a device specifically says to disconnect the charger after a full charge. There's so much mythology and repeated nonsense out there about batteries, chargers, and how they work!

Leave it in the charger as long as you want and it won't hurt the battery. It takes about 9 hours to fully charge. Therefore, I suggest you have two batteries.
