Hi! I would like to know what type of battery can this circuit charge ?

I know that on the site is mentioned lead acid battery, but I wanted to know if it is compatible in particular with gel batteries ?
With the appropriate voltage and current limits, it will work with flooded lead-acid, AGM lead-acid, gel-cell lead-acid, or the various rechargeable lithium chemistries.
