Points to consider for optimum use
- Charger configuration: To achieve its maximum service life, this battery requires precise setting of charging voltages.
- To avoid irreversible damage, the recommended values must be observed.
- Charging and discharging currents: We advise you not to exceed the currents recommended by the manufacturer.
- Excessively high currents can lead to premature wear and tear.
- Technology comparison: For equivalent weight and size, lithium technology offers superior storage capacity. The energy efficiency of a GEL battery (charge/discharge) is around 85-90%.
