12 Which Battery Type? HOPPECKE Batterien GmbH & Co. KG Bontkirchener Straße Brilon-Hoppecke

13 Requirements of a solar battery type High charge / discharge efficiency Minimum self discharge Reasonable price Maintenance-free types Requirements of a solar battery and Low maintenance types Resistance against deep discharge Reduced space in horizontal installation battery with fixed electrolyte High cycle life in partial state of charge (PSoC)

14 Designs of lead acid batteries Vented cells solar.power Sealed cells solar.power Liquid electrolyte Open system Direct exchange to the atmosphere Low maintenance, cells need to be topped up with water from time to time Fixed electrolyte in Gel or AGM Contact to the atmosphere by valve regulation In maintenance-free cells; no water topping required (sealed system) Advantages: High cycle lifetime Robust design Advantages: Maintenance-free High energy density 1/4 of air ventilation compared to a vented type recombination Maintenance intervals depend on water consumption Water consumption influences lifetime
