can this machine discharge residual charge remaining in a battery before recharging it?

It appears that only the NiCAD battery type will discharge in this unit before charging it. I have some old NiCAD's & watched the charging status & it shows that it's discharging before it switches to charge status.

There is no re-charge, it's battery operated. There is a round battery compartment located on the back.

I know that it had a charge, but regardless, I always try to put my batteries through a full charge and drain cycle as many times as possible when I first get them. It helps condition the batteries for max performance.

It's possible that it doesn't. I just needed it for an emergency charge to get me out of a bind while on vacation. I still use my primary charger 99% of the time. I will say though, the time I used it I didn't notice that the battery discharged noticeably faster.

Yes, to a point. While no damage is done to the charger or batteries outright there will be over a period of time be a shortened life of the batter itself. As with any rechargeable power source it is best to deplete it as low as you can before recharging. Leaving it constantly plugged in means continuous heat which shortens the life span of the battery.

Yes, but you never know when it is fully charged. I leave one battery in it all the time so that I always have one fully charged.

Yes, just like any other charger but you can leave it hooked up after charging is completed. If the dead battery is no good, nothing will help.

Yes...however you would have very limited use before battery had to be recharged.

As far as we could tell, yes. The unit never fully charged when it was being used and charged at the same time, but the level of the battery did not go down, either. And it makes sense to us that it would not fully charge since using the unit was depleting the battery.

By pressing that red button, you can completely discharge the batteries before charging them. If you don't press the button it will the charge batteries from whatever percentage of charge they have to full charge!I think it's a great charger!

No. The battery is an integral built in part of the vacuum. It is rechargeable through the included charger only. This battery cannot be simy replaced once it reaches the end incurs useful life, though if you read through enough if these reviews someone posted instructions for how to do exactly that.

It is not reconmended cause the cycle of charging must be completed before use. It good idea keep a extra battery in your camera bag...

Hello John,Yes, this is a sealed, rechargeable battery. It arrives with the factory charge which is usually around 95% of capacity. It can be used right away to start the machine. However, if you have the time available, we recommend a top charge with a quality charger for 4-6 hours. Best Regards, Battery Supersite

Not while electrical systems are in use. It's for maintaining a charge during battery storage and recharging (slowly) after use.

You can put batteries in the machine without it being plugged in and they will discharge. This is a great machine that has lasted much longer than the cheap $20 chargers. Good quality and fast on charging.

I think any battery will discharge after a certain amount of time, that's why a trickle charger is used on larger batteries.

No, I have two batteries. When one is depleted, I put it in the charger and when charged I store it while I'm using the second battery. I usually don't need the fully charged one until the next weekend and the charge still lasts long enough to do all of my 1500 square feet of wood floors.
