Overview

Caterpillar invests time and resources into delivering batteries that continue to perform, even in the toughest applications.

3-5X INDUSTRY STANDARD IN 100-HOUR VIBRATION TEST
Cat HD batteries reduce vibration forces without suffering mechanical damage, losing capacity or electrolytes, and developing leaks.

ROBUST PERFORMANCE
Cat batteries undergo a 72-hour deep discharge/charge test and a 30-day complete discharge/recharge test to ensure they perform to our high standards.

EXCELLENT RELIABILITY
Cat batteries also undergo heavy duty lifecycle and cold soak tests that simulate extreme conditions. The batteries must maintain their ability to start the engine.
