2. "Must know" features and facts

2.1 Ultra high efficiency "green" battery charger

With up to 94% 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.

2.2 Durable, safe and silent

- Low thermal stress on the electronic components.
- Protection against overheating: the output current will
reduce as temperature increases up to 60° C, but the
charger will not fail.
- When the NIGHT or LOW mode are activated, the
maximum output current is reduced 25% of nominal, and
the fan will be off.

2.3 Temperature compensated charging

The optimal charge voltage of a lead-acid battery varies inversely
with temperature. The Blue Power IP22 Charger measures
ambient temperature during the test phase and compensates for
temperature during the charge process. The temperature is
measured again when the charger is in low current mode during
float or storage. Special settings for a cold or hot environment are
therefore not needed.

2.4 Adaptive Battery Management

Lead-acid batteries should be charged in three stages, which are
[1] bulk or constant-current charge, [2] absorption or topping
charge and [3] float charge.
Several hours of absorption charge are needed to fully charge the
battery and prevent early failure to sulfation¹.
The relatively high voltage during absorption does however
accelerate aging due to grid corrosion on the positive plates.
Adaptive Battery Management limits corrosion by reducing
absorption time when possible, that is: when charging a battery
that is already (nearly) fully charged.
