I recently got some "charge controllers" where you set the voltage and cut off and it protects the battery regardless of type. one is a LV ( which is the DC voltage) and the other is HV (main grid) controllers which will cut or turn on charging. 
This is great if you have winter solar battery issues and need to have a "emergency charge" put into place.
