The KeyLine Chargers Mini-Pro line has the following special features: 

Reverse Polarity Protection:

  The charger can electronically and automatically 

determine if the polarity is correct or not and will never short circuit, cause a spark or harm 
the charger or battery as a result of reversing the polarity of the connectors.   

Short Circuit Protection

: The battery charger is protected and can sustain a short 

circuit connection directly across its DC outlet terminals indefinitely without damaging 
charger, equipment and without risk of shock, spark or excessive heat.   

IP65 Weather Proof Rating: 

The Mini-Pro charger line is a sealed unit unlike many others 

at this price point. This means that it has strong resistance to liquid and dust ingress. That means you 
can leave it in weather exposed environments and it will still perform beautifully.    It is not intended 
to be submerged in liquid. 

Surge Protection: 

The charger has an internal surge protection that will sustain a power surge 

between the power source and the battery being charged so that a surge will not damage batteries or 
equipment attached to the battery.   

Over Voltage Protection: 

This charger is smart and constantly monitors the battery’s voltage 

to ensure that it will not be overcharged and damage the battery.    This is really the reason why most
