Description

The maintenance-free AGM (Absorbent Glass Mat) battery by MW POWER, model 12V/20AH-MW, is a top-quality cell designed to provide reliable power in the most demanding conditions. Using advanced AGM technology, where the electrolyte is permanently immobilized in glass fiber mats, eliminates leakage risks and allows the device to operate in any orientation. This battery is an ideal solution for UPS emergency power systems, alarm control panels, fire protection systems, and emergency lighting installations.

Specification

Operational safety is enhanced by a robust ABS plastic casing and VRLA (Valve Regulated Lead Acid) valves, which automatically regulate the pressure inside the cell. The battery requires no water replenishment or constant electrolyte maintenance, making it a "fit and forget" solution. It is an excellent choice for installers and individual users seeking a compromise between high 20Ah capacity and compact dimensions, allowing for installation in standard system enclosures. By choosing MW POWER, you are investing in a proven brand and a guarantee of continuous operation for your devices.

A key advantage of this model is its extended design life, ranging from 6 to 9 years, which significantly exceeds standard market solutions. Due to low internal resistance, the battery handles sudden power surges perfectly, which is essential for the stable operation of security systems. The product is also characterized by a very low self-discharge rate, allowing for longer storage periods without the need for frequent recharging.

Construction Technology

VRLA (Valve Regulated Lead Acid) AGM (Absorbent Glass Mat) - electrolyte bound in glass fiber mats, ensuring maintenance-free operation and sealing.

Voltage and Capacity

Nominal voltage: 12V. Nominal capacity: 20Ah. This parameter defines the ability to power an electrical circuit with a given current intensity for a specified time.

Charging Parameters

Maximum charging current: 6.2 A. Recommended buffer charging voltage: 13.5V - 13.8V. Cyclic charging: 14.4V - 15.0V.

Terminal Construction

M5 screw type connector. Ensures a durable and low-resistance mechanical connection with the electrical installation, resistant to loosening.

Lifespan and Durability

Design life: 6 - 9 years when operating at a temperature of 20-25°C. The product stands out with greater durability compared to standard lead-acid batteries.

Safety and VRLA

The device features one-way safety valves that open upon excessive pressure increase inside the battery, protecting the casing from bursting.

Sealing and Operating Position

Hermetic construction prevents electrolyte leakage even in the event of casing damage. Can operate vertically and horizontally.

Discharge Characteristics

Very low internal resistance allows for delivering high power in a short time, which is critical for UPS systems during power outages.

System Applications

Alarm systems, fire protection systems, UPS power supplies, emergency lighting, automation systems, cash registers, portable devices.

Environmental Conditions

Optimal operating temperature: 20°C - 25°C. The battery can operate in a wide temperature range, though high temperatures shorten its lifespan.

Mechanical Resistance

Casing made of high-quality ABS plastic, resistant to impacts and most chemical substances.

Self-discharge

Low self-discharge level (approx. 3% per month at 20°C) allows for long storage without losing nominal parameters.

Physical Dimensions

Width: 180 mm, Height: 167 mm, Depth: 76 mm. Compact design facilitates installation in control cabinets.

Device Mass

Net weight: 5.83 kg. High weight indicates the thickness of the lead plates inside the cell, which translates into real capacity and durability.
