3) Voltage: 12V When fully charged, automotive batteries should measure at 12.6 volts. However, this measurement should be from 13.7 to 14.7 when the engine is running. If the battery tester 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. 4) 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 EN I 12 Gel Cell Battery (Gel) & VRLA Battery: Gel batteries are similar to fol oded batteries. Although for this type, calcium replaces the antimony in the lead plates, and silica is added to the electrolyte solution, turning the liquid into a gel. Absorbent Glass Mat Battery (AGM):
AGM batteries are designed to deliver powerful bursts of starting amps and run for a long time. "Absorbed Glass Mats" are used to cushion the ultra-thin lead plates, allowing manufacturers to include more leads into one battery and provide more power. AGM batteries are divided into two categories according to the cell structure. They can be AGM FLAT PLATE and AGM SPIRAL. This type of battery is ideal for vehicles with automatic start-stop applications and braking energy recovery.
