To make the battery in your robot vacuum last longer, you can follow these tips:
Full Charge and Discharge Cycles: Occasionally, allow the robot vacuum's battery to discharge almost completely (around 10% or so) before recharging it to 100%. This practice helps calibrate the battery gauge and ensures more accurate battery level readings over time.
Avoid Deep Discharges: While occasional full charge and discharge cycles are beneficial, try to avoid frequent deep discharges as they can put extra stress on the battery. Recharging the vacuum when it has around 20-30% battery remaining is generally sufficient.
Avoid Overcharging: Many modern robot vacuums have smart charging circuits that prevent overcharging. However, to be safe, avoid leaving the vacuum on the charger for extended periods after it's fully charged.
Store in Optimal Conditions: If you won't be using the robot vacuum for an extended period, store it in a cool, dry place with a battery charge level of around 50%. Extreme temperatures can degrade battery performance.
Keep the Vacuum Clean: Regularly clean the vacuum's brushes, sensors, and wheels. A clean vacuum operates more efficiently, reducing the workload on the battery.
Check for Updates: Ensure the vacuum's firmware and software are up to date. Manufacturers often release updates that optimize battery management and performance.
As for recharging the vacuum when it has 70% battery left after cleaning, it's generally not a problem. Lithium-ion batteries, which are commonly used in robot vacuums, don't have a "memory effect" like older battery technologies. This means you can recharge them at any point without significantly impacting their overall capacity or performance.
In fact, recharging your robot vacuum with 70% battery remaining may help prolong its battery life. Frequent shallow discharges (from, for example, 70% to 100%) are less stressful on the battery than deep discharges, and lithium-ion batteries tend to last longer when they are not fully discharged regularly.
Remember that battery life will naturally degrade over time due to the nature of the battery chemistry. However, following these tips can help you maximize the lifespan and performance of your robot vacuum's battery.
