Charge and run times
While handheld vacuums come with the benefit of being cordless, they do require batteries to operate. In the past, one of the greatest downfalls of handheld vacuums was battery life. Nowadays, however, lithium-ion batteries can be used as a power source, greatly improving the battery life and functionality. Keep in mind, however, that not all models come with lithium ion batteries, thus you should purchase your model accordingly.
Lithium-ion batteries are rechargeable batteries powered by the movement of lithium ions back and forth when charging and discharging. They’re most commonly used in household electronics and are thus suitable for handheld vacuums.
There are several advantages to lithium-ion battery models compared to other types:
• They can hold charge more effectively than other models, allowing for prolonged use. For comparison, lithium-ion batteries usually lose 5% charge per month, whereas other popular models can lose up to 20%.
• They weigh less than other models, allowing for more power and making the vacuum easier to carry around
• You do not need to fully discharge lithium-ion batteries. With many batteries, the run-time will decrease after partially charging them multiple times- this is known as the “Memory Effect.” These batteries are usually discharged fully to avoid losing overall run-time. Lithium-ion batteries, however, have no memory effect, and can be charged whenever you desire.
There are a few drawbacks to be kept in mind with lithium-ion batteries however:
• They are very sensitive to high temperatures and thus flammable
• They also should never be fully discharged as this can ruin them permanently.
