Hi sub ,
Thanks for the info
I haven't tested a lead acid yet ,
I have been down to my club Sunday today, one of the members has the same charger , I asked him what the fan does when he charges ,
he said if the battery is a 7.2v
1800mah set charge rate at 1.8amps the doesn't run
2300mah set charge rate at 2.3amps the fan will run
I tested some of my batteries tonight
4200mah set charge rate at 4.2amps the fan ran
2200mah set charge rate at 2.2amps the fan stopped and started during charging
1800mah set charge rate at 1.8amps fan did not run..
Not sure what's right
I did try discharging the fan didn't come on and the charger did get very warm
I will contact the company where it came from to ask them
Thanks again
Spud
