2. "Must know" features and facts
2.1 Blue Smart version only
Set-up, monitor and update the charger (add new features when
they become available) using Apple and Android smartphones,
tablets or other devices.
2.2 Ultra high efficiency "green" battery charger
With up to 95% efficiency, these chargers generate up to four
times less heat when compared to the industry standard.
And once the battery is fully charged, power consumption
reduces to 0,5 Watt, some five to ten times better than the
industry standard.
2.3 Durable, safe and silent
- Low thermal stress on the electronic components.
- Protection against ingress of dust, water and chemicals.
- Protection against overheating: the output current will
reduce as temperature increases up to 60°C, but the
charger will not fail.
- The chargers are totally silent: no cooling fan or any other
moving parts.
2.4 Reverse polarity protected
Once the battery is connected, the charger immediately detects
voltage and polarity. If the battery is connected incorrectly, all
status-LEDs will start blinking. No sparks will occur.
2.5 Recovery function for fully discharged batteries
Most reverse polarity protected chargers will not recognize, and
therefore not recharge a battery which has been discharged to
zero or nearly zero Volts. The Blue Power Charger however will
attempt to recharge a fully discharged battery with low current
and resume normal charging once sufficient voltage has
developed across the battery terminals.
2.6 Temperature compensated charging
The optimal charge voltage of a lead-acid battery varies inversely
with temperature. The Blue Power IP65 Charger measures
