Hi, Numpty here!
We have 2 x 12v 110A gel leisure batteries, and a Victron 2 x 140w Polycrystalline solar system with a 15A - MPPT controller. The monitor is a NASA BM-1, which is excellent and which i have learned to stare at lovingly over the past 7 months - especially when it tells me my batteries are at %104 after a sunny day!
We are on a landline at the moment and are at the stage where the solar is't cutting it for charging the 12v, even though it's only used for LED lights and the water pumps.
I have a "Ring Automotive Workshop Charge20" battery charger here, says it's suitable for lead acid & gel. 3 charging modes -
1) 80A rms 55A dc 12v Engine Start.
2) 20A rms 12.8A dc 12v Fast Charging.
3) 3A rms 2A dc 12v Slow Charging.
Questions:
Is it true that my leisure batts can get "lazy" if not discharged and charged regularly? (i was running everything through the inverter when the solar was doing well i.e. recharging to %104 at least every other day.. We are not huge power users by any means..)
How do i use this charger properly? Should i isolate the 12v before connecting (the manual says +itive then -ative) the croc clips? Or is it enough to turn the inverter off?
Assuming the monitor is telling me the batts are, say, 80% charged, which charging mode should i use? Does this charger automatically go into "float" mode?
All help most gratefully recieved - have been told that the batteries are in very good nick for their age and would like to keep them that way!
:-)
