hello folk
as promised our procedures on reconditioning batterys
be advised we did not follow standard procedures but have results so replication is at your own risk but we like to see your results when you try
we started with a really dead battery 225AH
after first charge witch did not go above 12.3 volt.... (dead in the water) it lasted 5 seconds on a load of 55 watts off the charge till 11 volt
so we did charging runs on a single coil setup and discharges whilst under charge of the wheel. (charging time in the beginning around 1 to 2 hours)
discharges timed around a minute whilst under charge
after a week suddenly we broke the sulfatation this way and started to see discharges over an hour still at 55 watt and under charge
the funny part is that in this stage you could see in some batterys a sudden rise in voltage during the discharge indicating you brake the sulfate
now we changed the setup to a 3 coil machine and raised the discharge to 130 watts to reach c20 values
charging went now well above 14 volt and discharges only to 12.40 under discharge
from this point on we started to see better and better results but still we used the system of discharging under charge of the wheel to let the spikes help dissolve the sulfate
we did try the discharge after a resting period and unhooked but then the results where a lot slower or even no progress over 10 cycles
so if you want to try to do it this way always leave it at the wheel.
you can safely go deeper then 12.4 under discharge till 12 volt just note the recovery voltage when standing. it should return to 12.4 volt
this info i got from the varta factory
i hope i can help out this way
kind regards
