Not in MY world, Perhaps in yours... CV-CC means Constant Voltage (CV) - Constant Current (CC)... There is Nothing about a pulse involved...Because a "Pulse" isn't constant... It (Pulse Mode) charging has a number of serious issues involved... The main one being that when loss of capacity (Age/Use) occurs the charging algorithm needs to be aware of the DV/DC (Delta Voltage/Delta Current curve and modify the charge cycle accordingly to compensate for low capacity and to warn the user that the battery is near it's failure point... Assuming that the device is monitored periodically. I used it for many years to charge SLA (Gel Cells) batteries. I did however have a means of loading the battery and the controller monitored the recovery time from a timed load test to full recovery of the battery voltage when the solar panel voltage was at Max. This was also a very good way to tell when the solar paner was dirty or failing (amorphous silicon solar cells are plagued by loss of capacity...A 12V solar cell uses 26 to 28 (as I remember) .6V cells connected in series... It only takes one marginal cell to "Kill" a solar panel.When the recovery time started to diminish I lit an led (10 mS pulsed activity indicator) to indicate the beginning of failure.I should mention that the charger was thermally compensated because a 100% charge @ 20C is ~120% of a full charge @ 40C with an SLA type battery..

Still though that may not be good enough, pulse charging, check voltage, charge, check voltage, charge.. this is how most cc/cv chargers work.
