Multi-mode charging: Supports both fast charging and trickle charging modes. Fully charges in 2-3 hours, and automatically switches to trickle mode in the later stages of charging to reduce battery cell wear. Multiple safety protections: Integrated overcharge, over-discharge, and short-circuit triple protection mechanisms, combined with a flame-retardant casing, ensure battery stability even in extreme conditions. Low self-discharge standby: The self-discharge rate during idle periods is much lower than that of traditional batteries. Even if unused for a week, it can still retain over 80% of its charge, meeting emergency cleaning needs. More flexible adaptation to multiple scenarios: Whether it's cleaning pet hair in a household or dealing with a mixed environment of carpet and hard floors, it can consistently deliver power and clean without interruptions. No memory effect and maintenance-free: Can be used while charging without the need to fully discharge, requires no deliberate maintenance in daily use, greatly reducing usage complexity and fitting a busy lifestyle., Manufacturer: yunfeng shop
