Product type
VRLA (Valve Regulated Lead Acid) batteries are a type of lead-acid battery that is sealed and maintenance-free. They utilize a gel or absorbed glass mat (AGM) technology to immobilize the electrolyte, allowing for safer operation and reduced risk of spillage. These batteries are designed to provide reliable power for a variety of applications, making them a popular choice in both industrial and consumer markets.
| Type | Sealed lead-acid |
| Voltage | 6V, 12V, or 24V |
| Capacity range | 1Ah to 300Ah |
| Operating temperature | -20°C to 60°C |
| Cycle life | 300 to 1200 cycles |
When selecting a VRLA battery, consider the specific voltage and capacity requirements for your application. It's important to specify the expected cycle life and operating temperature range to ensure optimal performance. Additionally, inquire about certifications such as ISO or UL standards, which can indicate quality and safety. Quantities may also affect pricing, so provide an estimate of your needs when requesting a quote.

Typically, VRLA batteries last between 3 to 10 years depending on usage and maintenance.
Yes, but performance may degrade outside the recommended temperature range.
Yes, they are sealed and do not emit gases under normal conditions.
VRLA batteries are maintenance-free; however, regular checks for corrosion and terminal tightness are recommended.
They are ideal for backup power, telecommunications, and renewable energy systems.
AGM batteries use a fiberglass mat to absorb the electrolyte, while gel batteries have a thickened electrolyte for better performance in extreme conditions.
