Also, I looked at the Specs for your 30a charger, and the blurb says this:
" Step 5: Bulk
Begins the Bulk charging process based on the condition of the battery and returns 80% of the battery’s capacity.
Step 6: Absorption
Brings the charge level to 90% by delivering small amounts of current to provide a safe, efficient charge. This limits battery gassing and is essential to prolonging battery life.Switches to a constant current charge rate to bring your batteries close to 90% charge.
Step 7: Optimization
Finalizes the charging process and brings the battery to maximum capacity. In this step, the charger utilizes multi-layered charging profiles to fully recapture capacity and optimize the specific gravity of the battery for increased run time and performance. The charger will switch to Maintenance if the battery tells the charger that more current is needed."
It appears this charger is not up to the task of doing a fast abs charge? What does "small amounts of current" mean? And why is it switching to 'constant current' during abs??? This makes no sense. Hopefully it's just a typo, but one more reason to find out what the heck is going on while charging.
