Hi
While saving for a good agm battery, I am testing with a Varta car battery, but I am not sure which setting to choose to charge it via the 8 position rotary switch.
At the moment I am in position 2, default setting, but every day in less than an hour it is fully charged, I am using a 375w panel.
Best regards
Most car batteries are flooded type - clasically 14.7V absorption - so position three perhaps?
To guess charge time you'd need to tell us your estimated depth of discharge.
A funny thing about charge time with victron's adaptive algorithm is that if the start voltage is above 12.2V you only get one third of the absorption time (default 3 hours) = 1 hour. If a cloud comes past and you go back to bulk prematurely (but stay above 12.6V) you may only get one sixth = 30 minutes before it hits float. Settings you'll only see with a VictronConnect login.
I've never noticed the batteries taking damage from routine slight undercharging, presumably overcharging is more dangerous?
Thanks Jesse
Really I don´t know yet estimated deptht discharge, I use it as backup for my radios.
I try not to lower 12v.
In the 8 positions chart it doesn´t tell nothing about flooded acid battery.
For now I will continue leaving it in position 2
Hi,
I have the same problem than @tosteitor, what is the "position 2" and "position 3" ?
it's preset GEL Victron battery 1 and 2 ?
Thanks,
