IP65 - Charger Guide
Storage mode: less corrosion of the positive plates
Even the lower oat 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 connect-
ed 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 Smart IP65 Charger measures ambient 
temperature during the test phase and compensates for tempera-
ture during the charge process. The temperature is measured again 
when the charger is in low current mode during oat or storage. 
Special settings for a cold or hot environment are therefore not 
needed.
Li-ion battery mode
The Blue Smart Charger uses a specic charging algorithm for 
Li-ion (LiFePO₄) batteries, with automatic Li-ion under voltage 
protection reset.

Ultra high eciency “green” battery charger
With up to 95% eciency, 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 ve 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.
Reconditioning
A lead-acid battery that has been insuciently charged or has been 
left discharged during days or weeks will deteriorate due to sulfa-
tion. 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 Smart Charger 
however will attempt to recharge a fully discharged battery with 
low current and resume normal charging once sucient voltage 
has developed across the battery terminals.
