reads less than this standard, it means that the battery's resting voltage is weak. In this case, typically, the battery needs to be charged or replaced. 3) CCA: 650A (SAE) The CCA rating refers to how many amps a 12-volt battery can deliver at 0°F in 30 seconds while maintaining at least a 7.2V voltage. This means that the higher the CCA rating is, the easier the engine can be cranked in cold temperatures. Connect the Clamps to the Battery Terminals (See Figure 3.3.1) 1) Before connecting the clamps to the terminals, please use sandpaper to polish off the corrosion on the battery terminals. With this, you can avoid inaccurate test values.
2) Attach the red clamp to the positive (+) terminal, and connect the black clamp to the negative (-). • ALWAYS KEEP THE RED & BLACK CLAMPS FROM TOUCHING. • ALWAYS DISCONNECT THE NEGATIVE CABLE FROM THE BATTERY FIRST AND RECONNECT IT LAST. 3) Once the clamps are properly connected, the battery tester will power on automatically and be ready to conduct tests.
