Advanced Multi-stage Smart Battery Charger, Desulphator, and Conditioner
For Wet, Gel, and AGM Sealed Lead Acid Batteries

The Schauer Charge Master microprocessor-controlled charger makes it easy to keep your batteries fully charged. With a push of a button, you can select the type of battery being charged and the current that you need.

The Schauer charger has a few unique features not found on many other chargers. Here are two that particularly stand-out:

  1. The charger will automatically memorize your charging rate and battery type setting. When you use the charger again, it will use the last used settings.
  2. If the charger is connected to the battery, you can change the charge rate or battery type without damaging the unit or your battery.

What is sulfation, and how can the Schauer Charge Master help?

During normal use, small sulfate crystals form on the battery. This is normal and not harmful. However, when a battery goes for an extended period of time without use or maintenance (i.e. kept on a charger), the lead sulfate converts to a stable crystalline that deposits on the negative plates. These crystals lead to larger ones, which blocks the necessary chemical reactions the plates need to operate normally. This reduces your battery's life and makes it harder to charge your battery.

One of the major features of Schauer's Charge Master is the float pulse charging. This specialty feature blasts battery-ruining sulfation off the plates, conditioning the battery and prolonging the battery life. Your battery will be maintained, rejuvenated, and ready to give you longer service life.

Schauer Charge Master

I am old school using battery chargers used to either a roll around quick charger or 12X12 transformer. The Schauer amassed me in that it serves a 6 amp 3amp and trickle charge modes. Quite a lot of technology for the money.

This charger kept getting high praise from the dedicated techs on
I finally bought one.
It's probably smarter than I am.
The instruction manual could use a review and edit, but I figured it out, mostly.
Thanks for being there.

Decent Charger

Only thing I would change about it would be to add some mounting tabs to the body so it could be permanently installed.

Just what I needed, and wonderful tech advice over the phone

Knowing little about trickle chargers prior to my call, it was great to have a real person on the phone giving me some guidance (Amazon has it's advantages, but does not offer this). The Schauer Charge Master does what it is supposed to do, and will be a great help with extending the life of my marine deep cycle as well as my garden tractor battery (when stored over the winter). It's nice to know I don't have to worry about overcharging and ruining a very expensive gel battery.

Just Enter the Battery Type and You Are Done

I purchased the CM6A on a recommendation from Battery Mart and it is perfect for my AGM type battery. Michael McKinney was very knowledgeable and patient explaining the type of battery I had and how it worked and why it required this type of charger which had the necessary 6 amp capability. I leave it on when the car is not in use as it is a classic car and driven sporadically. Also I can use it on other battery types if I need to. Seems to be working fine and could not be more pleased.
