It is generally not recommended to leave a cordless vacuum on the charger all the time. While many cordless vacuums have built-in mechanisms to prevent overcharging, continuous charging can still have some negative effects on the battery's long-term performance. Here are some guidelines to help you optimize the battery life of your cordless vacuum:
Follow the manufacturer's instructions: Refer to the user manual or guidelines provided by the manufacturer for specific recommendations regarding charging and battery maintenance. Different models may have different requirements.
Charge as needed: It is best to charge the cordless vacuum as needed, preferably when the battery level is low or depleted. Avoid leaving it on the charger for extended periods after it has reached full charge. Overcharging can lead to decreased battery performance over time.
Avoid deep discharges: Lithium-ion batteries, commonly used in cordless vacuums, do not need to be fully discharged before recharging. In fact, deep discharges can be more detrimental to battery life. It is better to recharge the vacuum when the battery level is around 20-30% or higher.
Store properly: If you're not planning to use the cordless vacuum for an extended period, such as during vacations or long periods of non-use, it is recommended to store it with a partially charged battery. Most manufacturers suggest storing the battery at around 50% charge.
Temperature considerations: Extreme temperatures can negatively impact battery performance. Avoid exposing the vacuum or its battery to excessive heat or cold, as it can affect the battery's capacity and overall lifespan.
By following these guidelines, you can help maintain the longevity and performance of your cordless vacuum's battery. It's important to note that battery life can still degrade over time due to natural wear and tear, but proper charging practices can help optimize its lifespan.
