(4) Cranking Versus Deep Cycle Batteries

These flashcards cover the types of batteries, their characteristics, and important concepts related to battery life cycles.

What are Deep Cycle Batteries?

Batteries engineered for regular, significant discharge, capable of being repeatedly drained to a low state of charge and then recharged, making them suitable for applications like powering 'house banks' in marine or RV setups.

What are Cranking Batteries?

Batteries designed for rapid energy release with thin plates to maximize surface area and minimize acid diffusion time, optimized for short bursts of high current needed for engine starting.

What is Cycle Material?

Material in batteries that can degrade or shed during deep discharges and recharges.

Describe Deep Cycle Wet Cell Batteries.

Batteries with thick plates and tough construction, suitable for cycling and can withstand abusive charging conditions.

How do Deep Cycle Gel Cell and AGM Batteries work?

They have thinner plates than wet cell batteries and rely on tight packing of plates and separators.

What are the Life Cycle Testing Factors for batteries?

Factors affecting battery life cycles, including discharge rate, test termination voltage, and overall battery capacity.

What is the Discharge Rate?

The rate at which a battery is discharged, typically 20% of the rated capacity.

What is Termination Voltage?

The voltage level at which a battery is considered fully discharged during testing.

What does the C5 Rate indicate?

A measurement indicating that a battery is fully discharged at a rate allowing complete discharge in 5 hours.

For what applications are Deep Cycle Batteries suitable?

Deep cycle batteries are recommended for various electronics due to their design and capabilities.

When is a battery considered to have reached 'Battery Death'?

When a battery is reduced to 50% or even 80% of its overall capacity it will fail fairly quickly and be labeled as dead.
