Blue Power IP65 charger 24V/5A + DC connectors Victron

Reconditioning
A lead-acid battery that that has been insufficiently
charged or has been left discharged during days or
weeks will deteriorate due to sulfation. If caught in time,
sulfation can sometimes be partially reversed by charging
the battery with low current up to a higher voltage.

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.

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.

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.

Storage mode: less corrosion of the positive plates
Even the lower float charge voltage that follows the absorption
period will cause grid corrosion. It is therefore essential to reduce
the charge voltage even further when the battery remains connected
to the charger during more than 48 hours.

Temperature compensated charging
The optimal charge voltage of a lead-acid battery varies inversely
with temperature. The Blue Power IP65 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.

Li-ion battery mode
The Blue Power Charger uses a specific charging algorithm for
Li-ion (LiFePO₄) batteries, with automatic Li-ion under voltage
protection reset.
