20th Annual Technical Forum: Batteries

Q: What’s the difference between a regular car battery and an AGM car battery? A. A conventional 12-volt lead acid car battery contains liquid electrolyte (sulfuric acid) between the lead cell plates while an “Absorbent Glass Mat” (AGM) battery contains no liquid. The acid is suspended in boron silicate (glass) mats sandwiched between the lead

Rotating Electric In Older Vehicles Makes For Sales Opportunities

Higher electrical demands on the charging systems in most late-model vehicles combined with high underhood temperatures has helped increase heat-related alternator failures.

Car batteries are a frequently replaced underhood component, more so than many other parts such as spark plugs, plug wires, sensors, water pumps, alternators, starters, even belts and hoses. The typical car or light truck will probably go through four or more batteries during its lifetime. The service life of most wet cell lead-acid batteries

When To Replace Sensors And Why

Sensors are designed to last the life of the vehicle or until they wear out.

ASE PS2 Test Preparation Guide: Electrical System

● BATTERY — Provides current for cranking the engine, and to supplement the electrical needs of the vehicle. Automotive 12-volt batteries are usually located in the engine compartment, but some may be mounted elsewhere (under back seat, in the trunk, behind the inner fender splash guard, etc.). Most are maintenance-free and require no make-up water
