Battery Selection

Provided by: ToolingU

“Battery Selection” discusses the factors by which batteries are rated and other considerations that go into selecting an appropriate battery. It also describes many of the most common types of batteries. To choose an appropriate battery, check the amp-hour, reserve capacity, and cranking amperage ratings. Also consider rechargeability, life span, size, weight, environment, and total cost. Understanding the factors that go into selecting a battery is important because so many devices rely on batteries for power. If the wrong battery is chosen for an application, it may not be strong enough or be able to operate for the required length of time. In some cases, using the wrong battery can even lead to safety hazards. However, choosing appropriate batteries for different applications ensures that devices will work optimally and prevents unnecessary costs.
