Hello, I am dealing with an issue regarding a battery charger and would like to post about it. I have a 24-volt / 100-amp charger. Since I replaced the batteries, I noticed that the charging level does not exceed 80%, but it also does not drop, with the charging current being 0, and sometimes even negative.
I forced it into Boost mode by setting DIP switch 8 to the left, and the charge increased by 5% after hours during which the charging current was 4.5 A (in Boost mode). I replaced the temperature sensor with a new one, but nothing changed. I opened the charger’s cover, and both voltage and temperature LEDs are green.
I should mention that both the charger and batteries are located outside at approximately 40°C but are protected from direct sunlight.
I don’t know what else to do. Could you give me some advice? Thank you in advance!
Hi,
Thank you for your reply.
So, i attached some photos with my batteries specifictions.and charger type.The last strange thing wich has been observed was that from 84% jumped direct to 100%. Wtf?!
All the values are showed on MPA computer.I’m working in a yacht.please see attached
Well, the victron smartshunt synchronizes SoC to 100% if the absorption voltage is reached and the current falls below a specified level for a specified time.
Between full charges the system adds and substracts Ws ( with factors for charge and discharge, fi peukert and efficiency) to keep track of SoC, but may be off by some % if the last full cycle was long ago.
So probably your batteries have the same mechanism ?
