I would like to purchase an expensive, top of the line cordless rechargeable hand vacuum cleaner. I would appreciate information as to explanation concerning the
Loss of power while the item is sitting on the shelf. How can I purchase a cordless rechargeable hand vacuum cleaner with a RECENT battery. The sales clerk has one but informed me that he found out that it is from mid 2011. I appreciate all advice and information. Thanks.

It's the number of recharges that shortens the life not how long its been on the shelf.

Can you please explain again... are you saying that rechargeable and regular batteries will NOT lose any power, unless they are used?
Thank you!

I said nothing about regular batteries but they will last up to 10 years on the shelf if you want to know. A rechargeable battery, which is what you'll get in that vac, is good for several thousand recharges. It's the number of recharges that finally starts counting down until the battery is no longer any good and can't take a charge . Sitting on a shelf since 2011 has not shortened the number of recharges the battery will accept.

Hi,
I would suggest one with the lithium-ion or lithium-polymer batteries because they produce a steady flow of amperage during a charge cycle. The ni-cad batteries slowly go down. In other words one gradually reduces in strength and the other stays at full power until very near the end.
Peace,

Thank you for your reply. I was wondering if you might know if it is better to keep it plugged in all the time, as mine is now. And then I might use it for a few minutes but never until it is entirely out of power. Thank you.

Hi,
Most people do. That way it is always ready to go.That is another reason to get th lithium-ion battery; they do not form a "memory." The ni-cad variety will form a memory of sorts when they are partially discharged and then recharged, i.e. it form an artificial place that the battery considers discharged. It is correctible by fully discharging and recharging, usually three times in succession.

I have a Dyson handheld cordless. Expensive, powerful, easy to clean. I don't keep it plugged in; it doesn't run down between uses. But beware - the more powerful the vacuum, the shorter the amount of time you have on each charge.
I have no floor vacuum at all - just a broom and a swiffer.

" keep it plugged in all the time", most people do but read what the manufacturer has to say.
