Charge‑and‑Go Operation
Lead‑acid batteries only sustain around 500 deep charge‑discharge cycles and suffer from charge memory effect, with a service life of roughly two years. By contrast, lithium‑ion batteries feature high durability and zero charge‑memory effect, supporting charge‑and‑go usage with approximately 1500 charge‑discharge cycles.
A fully‑charged floor scrubber normally runs for 3 to 4 hours. For high‑traffic cleaning sites, if the total daily runtime of the scrubber exceeds its battery capacity, operators risk triggering the memory effect when charging conventional lead‑acid batteries. Improper long‑term charging habits will shorten battery service life. Lithium‑ion batteries solve this pain point: they support charge‑and‑go operation. You may charge them during lunch breaks or other downtime without harming battery life.
Faster Charging Speed
Lithium‑ion batteries charge much faster. A full charge for a lead‑acid battery normally takes about 8 hours, while the fast charger paired with Liangyuxi long‑range lithium‑ion batteries completes a full charge in merely 4 hours. For heavily‑used cleaning equipment, lithium‑ion batteries drastically cut unnecessary charging waiting time and boost equipment operating efficiency.
Longer Endurance
At the same rated capacity, lithium‑ion batteries are smaller and lighter than lead‑acid batteries. Given similar physical dimensions, lithium‑ion batteries deliver higher power storage. This means your cleaning equipment runs longer on a single charge without frequent recharging.
Low Self‑discharge Rate
Lithium‑ion batteries have far lower self‑discharge than lead‑acid batteries. When left idle, a lead‑acid‑powered cleaning device may drain completely within one month and suffer deep discharge, commonly known as "battery starvation". Severe deep discharge may render the battery irreparable.
Cleaning equipment fitted with lithium‑ion batteries can sit unused for much longer. That said, regular use is still recommended for cleaning machines, as they deliver their full value only when put into service.
Over‑charge Protection
Commercial lead‑acid batteries generally lack built‑in over‑charge protection. Excessive charging duration will easily damage lead‑acid accumulators. Lithium‑ion batteries avoid this risk with comprehensive protective functions: high‑low temperature protection for charging and discharging; cell‑level over‑charge / over‑discharge voltage protection; charge‑discharge over‑current protection; cell balancing; short‑circuit protection and charging alerts. These features help extend battery service life and enhance operational safety.
Slow Capacity Degradation
Due to inherent material properties, frequent use and improper operation, lead‑acid batteries experience rapid capacity fading, resulting in shorter runtime and lower working efficiency. It is reported that lead‑acid batteries see roughly 50 % capacity loss after one‑year use, versus only 10 % for lithium‑ion batteries. Lithium‑ion batteries normally serve for about five years. With proper daily care, you will incur almost no extra battery‑related costs within five years.
Excellent Low‑temperature Performance
E‑bike users may notice that a new lead‑acid‑battery‑powered e‑bike can travel about 40 km in summer yet drops to merely over ten kilometres in cold winter. Research shows lead‑acid batteries retain less than 60 % of their performance in low‑temperature environments, whereas lithium‑ion batteries maintain over 95 % performance under cold conditions.
