What is the best battery powered hand vacuum?
There are a lot of options on the market nowadays for handheld vacuums. The vast numbers almost make it impossible to pick one or two products to be marked as the best. However, here we try to bring you the best choice of battery powered handheld vacuums based on product customers' reviews and product specifications. Our choice is the Dyson V11 handheld Vacuum.
Dyson company has made a reputation for itself on the vacuum market. The Dyson V11 has 40% more suction power than its predecessors. Not only it is a powerful vacuum, but it is also an intelligent one. Yes, you read it right, this is an intelligent vacuum. It senses whether you are vacuuming on a hard or soft surface, that way it can adjust its suction power to accommodate the surface it is vacuuming.
The Dyson V11 has an LCD display on the back of the unit, which displays all the information you need to know. Whether it is the suction mode, how much you have left before battery is run out, whether to change from Eco to Boost mode, etc. The battery image changes from the color green to the color red when you run out of power.
Generally speaking, the Dyson V11 is one of the best battery powered handheld vacuums on the market, if not the best. And it is our choice.
What affects lithium battery working?
Lithium-ion rechargeable batteries require routine maintenance and care when handling and use. Lithium-ion batteries have a typical lifespan of around two to three years. Alternatively, 300 to 500 charge cycles, so whichever reached first. One charge cycle is calculated as the period of use from fully charged to fully discharged and dully recharged once again.
Lithium-ion batteries have a limited life span and eventually will lose their ability to hold a charge. Unfortunately, this aging process (loss of capacity) is irreversible. As Li-ion batteries age the length of time they power the product will decrease, until they cannot power the device anymore.
It is worth noting that you should only use specified adapters to charge your batteries. Using an undesignated charger will not only harm your battery but can be very dangerous as you risk the hazard of fire.
Another thing that affects the performance of Lithium ion batteries is Passivation.
Passivation is a phenomenon that affects Lithium batteries. In general, passivation is a thin layer film of Lithium Chloride (LiCl) that forms on the surface of the lithium anode. Lithium Chloride is a high resistance film layer between the electrodes. This film serves as a protection to the lithium anode from discharging on its own when the load is removed outside the cell. This film of Lithium Chloride is the reason why lithium batteries have a long shelf life, which can be over a span of ten years.
Passivation may cause a delay in voltage when a load is placed on the cell.
Lithium-ion batteries continue to slowly self-discharge when stored or even when not used. That is why it is recommended to check the battery status every now and then even the battery is not used.
The time Li-ion batteries take to self-discharge when stored depends on several things. The most important factor of those factors is the temperature the battery is stored in. Higher temperatures above 20oC reduce the battery storage life tremendously.
If by any chance, you are experiencing weather that is below the 0oC or above 40oC DO NOT, charge your battery at all. Charging batteries in these conditions may damage the battery and cause risk to your person as the battery may explode or catch fire.
Before storage, it is recommended to charge or discharge your Li-ion battery to around 40% and then store in a cool place like the refrigerator (do not use the freezer, and wrap your battery in an isolation cloth or bag). If you are going to store your battery for more than six months, then you need to charge your battery to around 50% every six months of storage (at least). When storing a Li-ion battery, remove it from the product. Do not store the battery while attached to the product.
If you performed the above steps when storing a Li-ion battery, you can reach a storage time of almost two and a half years.
Lifetime evaluation of the Li-ion battery is very tough to determine though. That is why; big companies are reluctant to issue a specific time warranty for Li-ion batteries. That is due to the fact that if you want to know the behavior or a Li-ion battery over the span of eight years, you have to actively test it for eight years in all conditions to make such a claim.
A Li-ion battery is in a state of constant loss of charge -unless you are charging it-. According to Cadex Electronics, a battery testing firm, fully charged Li-ion battery will lose around 20% of its capacity when stored for a year in optimum conditions. And an empty Li-ion battery will fall into a deep discharge state, where the battery's protection circuit will kick in locking the battery and its ability to recharge once again. To recharge a battery reached a deep discharge state you have to go to a specialist at it is a safety hazard to try to do it yourself.
The degradation of Li-ion batteries has nothing to do with the structural degradation of the electrode materials inside the battery during the charge and discharge cycles.
How do you choose the best lithium battery for hand vacuum?
When choosing a Lithium ion battery for your handheld vacuum. You must choose it to be compatible with the device. Check the provided manual for the following information:
" The Voltage
" The Energy Density
" The Charge Rate
" The Operating temperature range
" The service life of the battery.
Moreover, do not forget to read the safety section of the manual to know how to handle the battery or battery pack correctly and safely.
