Wind Turbine Batteries
Battery bank is the important part for a grid off wind turbine system. Aeolos provided lead-acid and GEL batteries for our customers.
Maintenance free lead-acid battery（AGM）
a. Low Cost: The cost is about 50% of the same capacity Gel battery.
b. Good capacity of large current and quick discharging, Performance stable and reliable. Normal service life will be 3 to 5 years.
c. Low self discharge rate: At ambient temperature 20°C, just 2% to 3% energy will be lost because of self discharging.
d. Safe, free maintenance;
Colloidal battery（GEL）
a. Excellent capacity of deep cycle dischargingb. Lower self discharge rate: At ambient temperature: 20°C, no more than 2 % energy will be lost because of self discharge, strong charging ability, high energy density, excellent capacity of large current and quick discharge.
c. Extended temperature range（-40～60°C）and there is no thermal runaway performance.
d. Long service life(6～10 years), non pollution, safe, more environmentally protection.
e. Free maintenance and easy installation.
