Offgridtec® AGM 51Ah 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, no matter what position the battery is in
• screwable M6 terminals instead of battery terminals (100% fixed)
• 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 manufactured in A-quality from 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
• ergonomic handle facilitates carrying 

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.
