In the field of supermarkets and road cleaning, the stable operation of equipment is inseparable from reliable power support. For budget-sensitive and practical scenarios, lead-acid batteries are still the mainstream choice with their high cost-effectiveness and mature technology. GEMBATTERY has been deeply engaged in lead-acid battery technology for more than 20 years and has launched professional-grade lead-acid battery solutions for cleaning equipment needs. With stable performance, ultra-long life and economic advantages, it has become a trusted choice for supermarket properties and sanitation departments.

1. Core requirements of lead-acid batteries in cleaning scenarios: durability, economy, and easy maintenance

(1) Durability for high-frequency operations

Data support: Supermarket sweepers work 5-8 hours a day on average, and road sweepers travel 30-50 kilometers a day on average. The battery needs to withstand a complete charge and discharge cycle once a day, with an annual cycle of more than 300 times

Pain point focus: Traditional lead-acid batteries are often scrapped within 1-2 years due to problems such as plate sulfidation and electrolyte drying, and the replacement cost accounts for 20%-30% of the total equipment cost

(2) Strict cost control

Budget pressure: Municipal sanitation projects and small and medium-sized supermarket equipment procurement budgets are limited. The initial cost of lead-acid batteries is only 1/3-1/2 of that of lithium batteries, which is more suitable for large-scale equipment configuration

Hidden costs: Maintenance convenience directly affects operational efficiency. Traditional batteries require frequent refilling and pole inspection, which increases labor management costs

(3) Bottom line requirements for environmental adaptability

Temperature challenge: The temperature inside the car can reach above 50°C in summer and as low as - 10℃, the battery needs to output stably within the range of -20℃~50℃

Vibration tolerance: The sweeper is constantly bumping during operation, and traditional batteries are prone to mechanical damage such as plate shedding and shell cracking

II. GEMBATTERY lead-acid battery: Three major upgrades break through traditional bottlenecks

(1) Plate technology innovation: Anti-sulfurization ability increased by 50%

Multi-alloy plate: Lead-calcium-tin-aluminum alloy (Ca content 0.08-0.12%, Sn content 1.5-2.0%) is used, gas evolution is reduced by 40%, and the self-discharge rate is reduced to ≤3%/month

Nano coating process: The surface of the plate is coated with a graphene modified coating, and the lead sulfate crystal particle size is controlled below 20μm (the traditional process is 50-100μm), delaying the sulfidation process

Measured data: In the standard charge and discharge cycle test (25℃, 5-hour rate discharge), the GEMBATTERY battery cycle life reaches more than 600 times, which is an improvement over traditional products 50%

(2) Structural reinforcement design: to cope with complex working conditions

Thickened ABS shell: the shell wall thickness is increased to 3.5mm (traditional 2.5mm), the impact strength reaches 15kJ/m², and it passes the 1-meter drop test without damage

Labyrinth exhaust system: the filling cap adopts a three-layer splash-proof design, which reduces the electrolyte overflow by 90%, while keeping the vent hole unobstructed and the internal pressure controlled at 0.02-0.05MPa

Seismic terminal: the connection between the pole and the shell adopts a rubber buffer structure, which can withstand 10-200Hz, 1.5mm amplitude vibration test to avoid welding point breakage

(3) Reduce labor management costs

Tool-free maintenance: equipped with a dedicated electrolyte filling port, supports glove operation, and shortens the single maintenance time from 30 minutes to 5 minutes

Corrosion-resistant pole: the surface is plated with lead-tin alloy (thickness>10μm), with an insulating protective cover, the corrosion rate of the pole is less than 5% (traditional products are 30%)

III. Full-scenario adaptation solution: precise matching of supermarkets and road cleaning

(1) Supermarket cleaning scenario: economical choice under high turnover

Typical configuration: 12V/100Ah battery is suitable for small and medium-sized sweepers, meeting the daily cleaning needs of 5-6 hours

Scenario value:

A single battery pack can support 2000㎡ supermarket cleaning all day (charged once/day), with a comprehensive cost of only 0.5 yuan/㎡

Maintenance-free design reduces equipment downtime and improves nighttime cleaning efficiency by 30%

Connected with the property ERP system, predicts electrolyte consumption through battery weight changes, and intelligently reminds refilling

(2) Road cleaning scenario: a hard-core choice with durability as the priority

Typical configuration: 24V/200Ah battery is suitable for large road sweepers, meeting the daily operation of 8 hours

Scenario value:

Capacity retention rate > 85% under -20℃ environment, no preheating required for winter operation, direct start

Full-load climbing (slope 15%), the voltage fluctuation is <0.5V, and the power output is stable and not stuck

GEMBATTERY's lead-acid batteries for supermarkets and road cleaning sweepers break through traditional bottlenecks with multi-alloy plates and reinforced structural design. They have the advantages of long life, low maintenance, and wide temperature adaptability. The total cost is reduced by more than 40% in 5 years. With high cost-effectiveness and reliable performance, it has become a practical choice for cleaning scenes, helping to efficiently protect the cleanliness of the city.
