Hi, I am Yanki, the founder of bisonclean.com. I have been in the cleaning equipment field for more than 5 years now, and the purpose of this article is to share with you the knowledge related to cleaning equipment from a Chinese supplier's perspective.

Floor cleaning machines, such as vacuum cleaners, floor scrubbers, and sweepers, play a vital role in maintaining cleanliness and hygiene in various environments, from residential spaces to commercial facilities. The effectiveness of these machines largely depends on the battery chosen to power them. Floor cleaning machine with the right battery has better run time, efficiency, and lifespan, ultimately leading to better performance and user satisfaction.

Considering how vital batteries are, it’s critical to comprehend the subtle differences between various battery technologies and their advantages to make an informed choice. This blog aims to guide readers in choosing the best battery for their floor cleaning machines, ensuring optimal functionality and improved operational outcomes.

Types of batteries for floor cleaning machines

Lead acid batteries

With a history of more than a century, one of the most common and traditional battery types in floor cleaning machines is the lead-acid battery. There are two primary varieties of these batteries: sealed and flooded. The lead-acid batteries consist of lead dioxide and lead sponge soaked in an electrolyte solution and are capable of operating at around 50% energy efficiency.

Commercial floor scrubbers most commonly use deep-cycle lead-acid batteries in 6V or 12V configurations designed for sustained power output over extended cleaning cycles in industrial and commercial settings.

Lithium-ion batteries

Lithium-ion is an advanced technology that has become increasingly popular in recent years and is often used in floor cleaning machines with advanced features. Lithium-ion batteries are known for their high energy density and light weight, which makes them perfect for gadgets that need a small and lightweight energy source.

The lithium iron phosphate batteries used in Elerein floor scrubbers offer excellent thermal stability and safety, with a cycle life of 2,000 to 5,000 charge-discharge cycles.

AGM batteries (absorbent glass mat)

AGM batteries are sealed, maintenance-free lead-acid variants that prevent leaks, resist shock and vibration. This not only allows for horizontal mounting and offers superior leak resistance compared to flooded designs, but also makes them more environmentally friendly than wet-cell (flooded) batteries.
AGM batteries are also heavier than flooded lead-acid batteries, requiring more operator exertion on walk-behind machines, and have a relatively long charge time compared to other battery types.

Nickel-cadmium batteries

Nickel-cadmium floor scrubber batteries offer good performance and a long cycle life but are not widely used due to their memory effect, which reduces effective capacity over time, and due to environmental issues.

Important things to consider when choosing a battery

1. Battery capacity and runtime

Battery capacity is measured in ampere hours (Ah), which is an indication of how much current the battery can deliver in a specified period of time. For example, a battery rated at 100 Ah can theoretically supply 100 amps for one hour, or 50 amps for two hours. Higher Ah ratings generally translate to longer runtimes, but it’s also important to match the capacity to the power requirements of the cleaning machine.

If the battery capacity is too low, the machine may not provide enough runtime for your cleaning chores, leading to frequent interruptions. A longer runtime means that machines can operate continuously without needing frequent recharging, which is particularly important in large areas that require extensive cleaning.

2. Charging time

Different battery types exhibit varying charging times, which can affect operational efficiency. To reduce downtime, consider how quickly the battery can be recharged. If you need the machine to function quickly, a shorter charging time will benefit you.

Lead-acid batteries: usually take several hours to fully charge.
Lithium-ion batteries: charge significantly faster, with some models fully charging in under two hours.

3. Battery weight and size

The size and weight of the battery can affect the balance and maneuverability of the floor cleaning machine. Heavier batteries can make machines cumbersome and difficult to handle, especially in tight spaces or when performing detailed cleaning tasks. A lighter battery, such as a lithium-ion option, enhances the ease of movement, allowing operators to navigate easily around obstacles and access difficult areas more efficiently.

In terms of storage and transportation, heavy lead-acid batteries require more robust storage solutions and can also complicate transportation. In contrast, lithium-ion batteries are lightweight and can be more directly integrated into various cleaning equipment configurations. As a practical reference, Floor scrubber 12V batteries weigh 50-80 lbs each and must be lifted with proper technique during replacement to avoid injury.

4. Comparing battery costs

The initial costs of different battery types, including gel, lead-acid, lithium-ion, and AGM batteries, can vary significantly. Floor cleaning machines with lead-acid batteries are usually the most economical choice upfront. Floor cleaning machines with lithium-ion batteries tend to be more expensive initially; however, their advanced technology often justifies the investment due to lower long-term costs. AGM batteries are also more expensive than regular batteries, but for certain consumers, the added benefits of AGM batteries compared to more advanced battery technology may not make up for their higher cost.

5. Lifespan and maintenance

Typically, lead-acid batteries have a lifespan of approximately 3 to 5 years, but this can be shorter with heavy use. Regular maintenance is necessary for lead-acid batteries to operate at their best. For example, check the electrolyte level and ensure the terminals are clean and free of corrosion, and charge regularly to prevent sulfation, which shortens the battery’s lifespan.

Lithium-ion batteries with longer cycle lives can withstand more cycles of charging and discharging before experiencing a discernible decrease in capacity. These batteries can last between 5 to 10 years with proper care. They also need less upkeep because their electrolyte levels don’t need to be checked or replaced regularly.

6. Environmental factors

Changes in temperature and humidity in the external environment can affect the life and performance of the floor cleaning machine battery. Generally, lithium-ion batteries are more adaptable to temperature changes than lead-acid batteries, and sealed batteries have a longer life in humid environments than unsealed batteries.

Batteries can also affect the environment. Proper disposal and recycling of batteries are essential to mitigate their environmental impact. When your floor sweeper is retired, the battery can be removed. Lead-acid batteries are highly recyclable, with over 95% of their components being recyclable, and typically need to be returned to the supplier or a recycling facility. Lithium-ion batteries are less toxic, but improper disposal can still cause environmental issues. Lithium-ion batteries contain valuable materials such as lithium, cobalt, and nickel that can be recycled by relevant recycling facilities, though their recovery rate is currently lower than that of lead-acid batteries.

Recommendations for choosing the right battery

Flooded lead-acid may suit operations with a full charging window and a reliable maintenance routine. AGM or gel may suit buyers who need a no-watering option. Lithium-ion may suit frequent use when the approved battery and charger support the required charging schedule.
Run time and frequency. Evaluate the use of the floor cleaning machine. If long run time or frequent use is required, there is no doubt that lithium-ion batteries should be selected.
Manufacturer support. Before ordering, request the battery warranty terms, coverage exclusions, service contact, and replacement-pack availability for the selected machine and battery configuration.

Conclusion

By understanding the different types of batteries, such as lead-acid, lithium-ion, AGM, and nickel-cadmium, and the key factors to consider in each, you can make the right choice.
