Rechargable 12v 4ah 10hr 12v4.5ah 20hr 12V5AH Battery For Small Low Power UPS Devices

Product Overview

The 12V 4Ah lead-acid batteries are mainly used in small, low-power UPS (Uninterruptible Power Supply) devices. As a core component of backup power systems, they provide short-term power to loads when the mains supply is interrupted, ensuring stable shutdown or temporary operation of equipment.

Core Characteristics

Voltage and Capacity Features:

• The nominal voltage is 12V DC, with small voltage fluctuations during discharge (usually maintained between 10.5-13.0V). It can provide a continuous and stable DC power supply for equipment, meeting the power supply needs of most 12V low-voltage devices.
• With a capacity of 4Ah 4.5AH 5AH, it theoretically can last about 8-10 hours under a 0.5A discharge current, making it suitable for short-term or intermittent power supply of small-to-medium power equipment.

Structural and Maintenance Characteristics:

• Sealed design: Adopting a valve-regulated sealed structure (VRLA), the electrolyte is absorbed in the separator, eliminating the risk of leakage. It can be installed in any direction (avoid inversion), making the application scenarios more flexible.
• Maintenance-free: There is no need to regularly add electrolyte or distilled water, which reduces maintenance costs and operational complexity, making it suitable for non-professional users or unattended scenarios.

Outstanding Advantages

Safety and reliability

• Lead-acid batteries have stable chemical properties, with no risk of overcharge explosion or violent combustion (compared with some lithium batteries), and have better safety in complex environments such as high temperature and humidity.
• The sealed structure avoids equipment corrosion caused by electrolyte leakage, and the gas emission during charge-discharge cycles is extremely small, making it suitable for use in indoor enclosed spaces.

Ease of use

• No special charger is required (most 12V universal chargers are compatible), the charging process is simple, and users can operate it without professional knowledge.
• It has a low self-discharge rate (about 3%-5% per month) and can retain power for a long time when idle, making it suitable for long-term storage as a backup power source (such as backup batteries for emergency equipment).

High flexibility in combination

• For higher voltage requirements, multiple batteries can be connected in series (e.g., 2 batteries in series for 24V, 3 batteries in series for 36V); This flexibility meets the voltage and capacity needs of different equipment.
