Car Batteries Q&A

What does the rating mean when selecting a battery?

Most batteries have an AMP-HOUR Rating. This rating refers to battery capacity which is calculated by multiplying the current flow of amperes by the time in hours of discharge. This rating is changed by manufacturers using different discharge periods. When selecting a battery, the Ah rating should only be used a general method of evaluating the battery’s capacity. The best ratings to use when selecting a battery is the Cold Cranking Amperage and Reserve Capacity.

How much voltage is required to charge a battery? What is the charging voltage?

When charging a 12-volt battery, a person can use a range of voltages. The minimum amount is 12.9 volts, but when this energy is used, the charge rate is prolonged. If the battery is discharged, a person can apply higher voltages. If the battery is being monitored for overcharging, voltages over 15V can be used safely. If the battery will just be left on the charger, the best voltage is between 13.6V to 13.8V.

What does the Cold Cranking Amperage rating mean when selecting a battery?

Cold cranking amps are the maximum amount of amperes that can be removed continuously from a car battery for 30 seconds at zero degrees F. If the amount of amperes goes above this amount, the voltages can drop below usable levels. The CCA rating is critical when selecting a battery that will start engines.

As a 12V battery is charging and discharging, what is the battery voltage range?

A car battery’s voltage changes on its condition. The open circuit voltage of a battery when the engine is off is 12.9 volts. A battery will accumulate non-chemical charge when being charged by alternator or charger so that the volts will be higher. When a battery is discharging, the voltage will drop to 10 volts or below. As long as the battery is above 11.8, it will typically still start a vehicle.

What does the Reserve Capacity rating mean when selecting a battery?

The reserve capacity rating is measured in minutes. It is the number of minutes that a battery can maintain voltage with a 25 amp discharge. The higher this rating, the more equipment the lights can run for longer periods without needing a recharge. This rating is the more accurate measurement of deep cycle service.

Will a car battery freeze?

If a battery is fully charged, the electrolyte is sulfuric acid. This acid has a freezing point of below -40°C. If a battery is fully discharged, the sulfate ions have been consumed, and the electrolyte is water. Water has a freezing point of 0 degrees C. So if the weather outside is cold and the battery will not accept a charge, warm it up first and then charged it.

What do the terms ‘battery cycle life’ mean?

A cycle is a movement from a fully charged battery to a fully discharged battery and then returning back to fully charged battery. The number of times a battery can go through this cycle is referred to as the ‘cycle life’. Typically, a manufacturer does not advertise the cycle life of their batteries because deep cycle batteries have not been tested for a life cycle and cranking batteries do not have a long cycle life.

After starting the engine, how long will it take to charge the battery?

This question is a little difficult to answer. Each battery is rated for cold cranking amps. If the battery has an 800 CCA, then it can be assumed it will take about 800 amps to start the car. If it is expected that a vehicle can be started in less than 10 seconds, it will take 2.2 amp-hours to start the car. If an alternator can source 80 amps, it could replace this in about 99 seconds.

Is there a difference between deep cycle batteries and starting batteries?

The term deep cycle just means a battery can be fully discharged and charged. However, a good deep cycle battery can handle thousands of hard cycles without losing its capacity. Deep cycle batteries can be used as cranking batteries. A cranking battery is only used for starting a vehicle and they cannot handle deep cycle use. When doing a car battery comparison, a person should pick a deep cycle battery when using the battery for cycling applications.

Does driving short distances flatten the battery?

During cold weather, a person typically has headlights, seat heaters, heater fans, heater pumps, defrosters, etc. all running on a short trip to the store. All of this equipment is a significant drain on a cold battery. Since the battery is cold, it has a harder time recharging. As the days grow longer and the weather heats, the battery will not be as flattened by short distances.

Does the battery need water before or after it is charged?

The water should be added before the battery is charged. When a battery is being charged, the process will create bubbles that help mix the acid. Many batteries will not consume water at a single charge. Most modern systems for charging have accurate voltage regulations that will not absorb any water. The modern sealed batteries will recycle the water, so it cannot be replaced.
