Offgridtec AGM solar battery 12V 122Ah 20HR, deep cycle (001485)

The 122Ah strong solar battery from Offgridtec is a sealed AGM lead-acid battery with high cycle resistance for use in solar, emergency power and energy supply systems.

122 Ah AGM battery with 12 V nominal voltage (capacity after 10HR: 120 Ah)

• Maintenance-free AGM technology with sealed housing
• Low self-discharge of approx. 2% per month at 25 °C

Thanks to maintenance-free AGM technology, low self-discharge and a high number of cycles, it is suitable for both cyclic applications and reliable standby operation. The robust ABS housing and durable construction make the energy storage a suitable solution for stationary applications with high demands on reliability and operational safety.

Reliable AGM energy storage for solar and emergency power applications

• Up to 500 cycles at 50% depth of discharge
• Up to 1,200 cycles at 30% depth of discharge
• Suitable for cyclic operation and standby applications
• Robust ABS plastic housing

Up to 8 years float charge or standby operation under suitable conditions

• AGM technology for low-maintenance operation

The battery uses proven AGM technology (Absorbent Glass Mat). The electrolyte is bound in glass fibre mats and cannot leak freely. As a result, the battery works completely sealed and requires no water refilling during operation. At the same time, this design enables high operational safety and reliable energy supply in a wide range of stationary applications. The lead alloy used and modern manufacturing processes ensure consistent performance and a long service life.

• Suitable for cyclic and stationary applications

The Offgridtec AGM 122Ah was developed for both regular charge and discharge cycles and standby operation. It is therefore suitable for, among others:

• Solar systems and off-grid systems
• Uninterruptible power supplies (UPS)
• Emergency power supplies
• Telecommunications systems
• Alarm and security systems
• Communication systems
• DC power supplies
• Automated technical systems

Due to its low self-discharge, the battery remains reliably ready for use even during longer idle periods.

• High cycle resistance for regular use

The achievable service life of a lead-acid battery depends largely on the depth of discharge (DoD). The lower the regular discharge, the more charge cycles the battery can achieve.

• Notes on charging

For a long service life, a temperature-dependent charging voltage is recommended. In cyclic operation, this is 14.40 to 14.60 V at 25 °C. For standby operation, a float charge voltage of 13.50 to 13.80 V is recommended. The maximum recommended charging current is 36 A. Charging technology matched to AGM batteries supports gentle and efficient operation.
