Product type
Lead-acid batteries are a type of rechargeable battery that uses lead dioxide and sponge lead as electrodes, with sulfuric acid as the electrolyte. They are one of the oldest types of rechargeable batteries and are known for their reliability and cost-effectiveness. Typically, they are used in applications requiring high surge currents, such as automotive starting, lighting, and ignition systems, as well as for backup power in uninterruptible power supplies (UPS).
| Nominal Voltage | 6V or 12V |
| Capacity Range | 20Ah to 200Ah |
| Cycle Life | 300 to 1,500 cycles |
| Weight | 10 to 60 kg |
| Temperature Range | -20°C to 50°C |
When selecting lead-acid batteries, consider the required voltage and capacity to ensure compatibility with your application. It's important to specify the expected cycle life and operating temperature range, as these factors can significantly affect performance. Additionally, inquire about certifications such as ISO or IEC standards, and consider the quantity needed for your project to receive accurate pricing and availability.

Typically, lead-acid batteries last between 3 to 5 years, depending on usage and maintenance.
Yes, lead-acid batteries are highly recyclable, with over 95% of their components being recoverable.
The most common types are flooded, sealed lead-acid (SLA), and gel batteries.
Regularly check the electrolyte levels, keep terminals clean, and ensure proper charging to extend lifespan.
When handled properly, lead-acid batteries are safe, but they contain hazardous materials and should be disposed of correctly.
Flooded batteries require maintenance and venting, while sealed batteries are maintenance-free and can be used in various orientations.
