SAFETY

Carefully read all operating instructions before 

using the SB-300

Wear proper protection when working around 

batteries.  

Be sure each test is complete before removing 

load clamps to prevent arcing and potential 

explosion from battery gases.  Keep sparks 

flames, or cigarettes away from batteries.  

Keep hair, hands, and clothing as well as tester 

leads and cords away from moving blades and 

belts.  

Provide adequate ventilation to remove car exhaust.  

In extremely cold temperatures, check for frozen 

electrolytic fluid before applying load.  Do not attempt 

to Load Test or charge a battery under 20 degrees.  Allow the battery to warm to room 

temperature before testing or charging.

  

Warning!  

Never attach the SB-300 to a battery that is connected to any other tester 

or charging unit.  Damage may result. 

CAUSE OF BATTERY FAILURE

Incorrect Application:  

Wrong size battery may have inadequate cold cranking Amp 

rating for original vehicle specifications.  

Incorrect Installation:

  Loose battery hold-downs cause excessive vibration, which 

can result in damage to the battery plates.  

Improper Maintenance:  

Low electrolytic fluid and corrosion on battery connections 

can greatly reduce battery life and affect battery performance.  

Age of Battery:  

If the date code on the battery indicates it is old, the failure may be 

caused by natural causes.  

Overcharging:  

Overcharging caused by a high voltage regulator setting or incorrect 

battery charging can cause excessive gassing, heat and water loss.  

Undercharging:  

Undercharging caused by a faulty charging system or low voltage 

regulation can cause lead sulfate to gradually build up and crystallize on the plates 

greatly reducing the battery’s capacity and ability to be charged.
