Offgridtec® AGM 2,2Ah 20HR 12V - Deep Cycle Solar Battery

Offgridtec AGM solar batteries are explicitly designed for use in solar and hybrid systems. AGM technology is clearly superior to conventional lead-acid batteries with liquid electrolyte and offers the following advantages:

Advantages of using Offgridtec AGM Technology

• absolutely safe from leakage, regardless of the position of the battery
• 100% maintenance-free over the entire service life
• Life expectancy up to 10 years (depending on usage pattern)
• Highest quality level: Our batteries are all A-quality and made of the best materials. This can best be seen in the weight of the batteries. Compare our products with those of other manufacturers!
• can be discharged deeper than lead-acid batteries
• mature technology, used in over 1000 Offgridtec solar systems
• very cycle-resistant, therefore predestined for use in solar systems

AGM batteries are somewhat more expensive to purchase than lead-acid batteries, but this pays off after just a few years, as lead-acid systems require much more maintenance and have a shorter life than AGM-based storage solutions.

Especially for smaller energy generation systems with a maximum storage capacity of 4-8kWh, AGM is the first choice.
