Maintenance-free lead battery with very low self-discharge
The Deep Cycle Series from Victron are premium GEL batteries that have a lifetime of up to 12 years and can be unloaded and charged up to 1800 times.
These gas-tight and light batteries are therefore ideally suited for heavy duty on electric vehicles, extremely frequently used solar systems (cycles), mobile applications and for starting motors with large currents.
Due to the very low self-discharging and the position independence, you can also be used in sailing ships and do not have to be removed during the winter.
