Why Do Cordless Handheld Vacuum Cleaners Prefer Lithium Batteries?
In recent years, cordless handheld vacuums have become a must-have appliance for modern households, offering unmatched convenience and powerful cleaning performance. A key factor behind their success is the adoption of lithium battery technology, which provides high energy density, fast charging, and long-lasting power. At Himax, we specialize in custom lithium battery solutions, including high-performance 24V 3Ah Li-ion battery packs, designed to enhance the efficiency and durability of cleaning devices. This article explores why lithium batteries dominate the handheld vacuum market and how advanced power solutions are shaping the future of home cleaning.
1.High Energy Density for Lightweight Design
One of the biggest advantages of lithium batteries is their high energy density. Compared to traditional nickel-metal hydride (NiMH) or lead-acid batteries, lithium-ion (Li-ion) and lithium-polymer (LiPo) batteries store more power in a smaller, lighter package.
Weight Reduction: A typical 18650 Li-ion cell (used in brands like Dyson) offers 200-250Wh/kg, allowing vacuums to weigh under 2kg while maintaining strong suction.
Compact Size: Lithium batteries enable slim and ergonomic designs, making handheld vacuums easier to maneuver.
Himax Insight: Our 24V 3Ah custom Li-ion battery pack is optimized for handheld vacuums, delivering 72Wh of energy in a compact form factor—perfect for balancing power and portability.
2.High Discharge Rate for Consistent Suction Power
Handheld vacuums require instant high-power bursts to maintain strong suction, especially when dealing with deep-cleaning tasks.
3C-5C Discharge Capability: Lithium batteries can deliver high current without voltage drops, ensuring stable performance.
No Memory Effect: Unlike NiMH batteries, lithium batteries do not lose capacity if charged before being fully depleted.
A 24V 3Ah Li-ion pack can support 9A continuous discharge, making it ideal for vacuums with 150W+ motors.
3.Fast Charging & Longer Lifespan of Lithium Battery
Consumers demand quick recharge times and durability—both areas where lithium batteries excel.
1-2 Hour Charging: Many modern vacuums (e.g., Tineco, Shark) support fast charging, reducing downtime.
500-1000+ Cycles: Premium lithium cells (Samsung, LG) retain 80% capacity even after years of use.
Our 24V 3Ah battery integrates smart BMS (Battery Management System), preventing overcharge/over-discharge and extending lifespan.
4.Eco-Friendly & Future-Ready of Lithium Battery
With increasing environmental regulations, lithium batteries are the cleaner choice:
No Toxic Metals: Unlike NiCd batteries, lithium-ion is RoHS-compliant.
Recyclable: Major brands (like Dyson) now offer battery recycling programs.
Industry Trend: Solid-state lithium batteries (under development) may further improve safety and energy density.
Conclusion: The Future of Handheld Vacuums Relies on Lithium Battery Power
Lithium batteries have revolutionized cordless vacuum cleaners by offering lightweight design, high power output, fast charging, and long life. As technology advances, we can expect even more efficient and sustainable battery solutions.
At Himax, we provide custom lithium battery packs (like our 24V 3Ah model) tailored for vacuum manufacturers, ensuring optimal performance, safety, and cost-efficiency. Whether you’re developing a new cleaning device or upgrading an existing model, our engineering team can help you find the perfect power solution.
