The category VRLA (Valve Regulated Lead Acid) Batteries represents the leading solution for reliable standby power (Standby Power) and stable energy in closed systems. VRLA technology, which includes the popular forms AGM (Absorbed Glass Mat) and GEL (Gel Electrolyte), is of closed type and zero maintenance, ensuring maximum safety.

At Zaps.gr, VRLA batteries are specially selected for:

• UPS (Uninterruptible Power Supply): Essential for the uninterrupted operation of computers, servers and critical equipment, protecting against power outages.

• Security & Alarm Systems: They guarantee the continuous operation of monitoring, fire detection and security systems, even in the event of a power outage.

• Emergency Lighting: They provide the necessary power to activate security lighting systems in buildings and professional spaces.

With features such as low self-dischargeThe shock resistance and the ability to be installed in various positions (except upside down), VRLA batteries are the most safe and economical option for each backup power application.

1. What is the basic difference between AGM and GEL VRLA batteries?

Both are sealed and maintenance-free, but differ in electrolyte technology. The AGM They use glass separators soaked in acid (liquid), offering higher discharge current and are ideal for UPS. GEL They use a gel electrolyte, which makes them more resistant to deep discharge and high temperatures, ideal for telecommunications or small photovoltaics.

2. How often should I replace the VRLA batteries in my UPS?

The service life of a VRLA battery depends on the design (e.g. 5-year or 10-year life) and operating conditions. High temperatures (above $25^{circ}C$) and frequent full discharges reduce the lifespan. For critical systems, replacement within the specified period is recommended, regardless of their apparent operation.

3. Can I use VRLA batteries for deep cycle?

While all VRLA batteries can withstand deeper discharge than conventional starting batteries, VRLA GEL are generally more suitable for deep discharge applications (e.g. small photovoltaic systems or golf carts). The VRLA AGM are optimized for high standby power and short, fast discharges (UPS).

4. Are VRLA batteries safe for indoor use?

Yes. VRLA batteries are sealed and gas emissions are negligible under normal operating conditions, making them safe for installation indoors in offices, homes or server rooms, unlike open-type batteries.
