Ritar 100AH 12V AGM Deep cycle Battery DC12-100 Vietnam

RITAR DC12-100 12V 100Ah Deep Cycle VRLA Battery

The RITAR DC12-100 is a dependable 12V 100Ah deep-cycle Valve Regulated Lead Acid battery developed for renewable-energy storage, backup power, and applications that require repeated charging and discharging.

Its deep-cycle construction uses strong grids, thick plates, and specially formulated active materials to improve performance during repeated deep-discharge operation. According to the datasheet, the DC series offers approximately 30% more cyclic life than the standby series.

With a nominal voltage of 12V and a rated capacity of 100Ah at the 20-hour rate, the battery provides reliable stored energy for solar systems, wind-energy systems, UPS and backup installations, mobility equipment, medical devices, and telecommunications applications.

Deep-Cycle Performance

The DC12-100 is designed for applications where the battery is regularly charged and discharged. Its internal plate construction supports repeated cycling and makes it more suitable for renewable-energy storage than a standard standby battery.

Reference Capacity

• C20 capacity: 100Ah
• C10 capacity: 95.2Ah
• C5 capacity: 85Ah
• C3 capacity: 75Ah

Battery runtime will vary according to the connected load, discharge rate, temperature, battery condition, and selected inverter efficiency.

High Discharge Capability

The battery supports a maximum discharge current of 1000A for five seconds, providing strong short-duration current for compatible equipment and loads with temporary starting requirements.

Its internal resistance is rated at ≤5.5mΩ when fully charged at 25°C, supporting efficient current delivery and dependable system operation.

Charging Parameters

For reliable charging and battery performance, the connected charger or inverter should be configured according to the recommended voltage and current limits.

• Maximum charging current: 30A
• Float charging voltage: 13.6V–13.8V at 25°C
• Cycle-use charging voltage: 14.6V–14.8V at 25°C
• Temperature compensation for float charging: -3mV/°C per cell
• Temperature compensation for cycle use: -4mV/°C per cell

The battery should be fully charged before initial use and before conducting a capacity test.

Low Self-Discharge

The monthly self-discharge rate is stated as less than 3% at 25°C. The battery may be stored for up to six months at 25°C before recharging is recommended. Storage temperature and duration can affect the remaining battery capacity.

Wide Operating Temperature Range

The battery is suitable for operation across a broad temperature range:

• Discharge temperature: -20°C to 60°C
• Charging temperature: 0°C to 50°C
• Storage temperature: -20°C to 60°C
• Recommended normal operating temperature: 25°C ±5°C

Operating the battery at elevated temperatures may reduce its long-term service life.

Durable Battery Construction

The battery is housed in a robust ABS enclosure and is supplied with an F12 M8 terminal as standard. Optional terminal configurations may be available depending on the product supply.

Its compact design makes it suitable for installation in battery cabinets, solar storage systems, UPS systems, and backup-power enclosures.
