Cranking Amps determine how much power you have to start your car in most climates. They are the number of amperes a lead-acid battery at 0 degrees Celsius can deliver for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12 volt battery).
This is the batteries ability to sustain a minimum vehicle electrical load in the event of a charging system failure. Under the worst conditions, (for example, winter driving at night) this minimum could require current for ignition, low-beam headlamps, windshield wipers and defroster whilst driving at low speed.
To find this out, consult the owner's manual for your car first. This should tell you proper size and cranking amps. You can also look up the make, model and year of your car on a battery application guide to determine the battery size to suit your vehicle. While using a battery with a higher capacity is recommended for older cars to improve starting, never use a battery with a lower capacity rating.
Automobiles demand more from a battery in freezing temperatures as the oil in the motor thickens and makes the engine harder to crank. Extreme cold reduces the speed at which a chemical reaction can occur, while increasing electrolyte resistance. Batteries must be kept at full charge during extremely cold periods.
Heat is the no.1 killer of a battery. Although over the short term it increases the performance of the battery, over the long term battery life is drastically reduced.
Check the battery terminals for signs of corrosion - the terminals and the attached cables need to be cleaned to ensure a good connection and proper starting. Removing any oil and dirt from the battery casing also reduces the risk of short circuiting.
Read and follow all warning labels prior to charging a battery, as a battery can generate explosive gasses. These instructions vary by manufacturer, and it is important to follow them to ensure the battery is returned to full charge. To ensure the best results, recharge the battery as soon as it has discharged. To charge an average fully-discharged battery using a 10-amp automotive charger, it will take approximately 8-10 hours at 80 degrees Fahrenheit to reach full charge. Warning: Once a battery has been fully charged, it should be disconnected from the charger immediately, as continuing to charge will severely damage the internal plates and shorten battery life.
Your battery may need replacement if you experience any of the following:
If you are experiencing any of these symptoms, you should have your battery and/or electrical system checked.
Yes they are 95% recyclable. We make a conscious effort to collect old batteries and ensure they are safely disposed of to keep NZ clean and green.
When storing an automobile battery, it is important to make sure it is at a full charge and the electrolyte level is full. A battery stored in a discharged state is susceptible to freezing sulfation and an increased rate of further discharge. The battery should be placed in a cool dry area, the cooler the better without going below 0 Celsius, that is well ventilated and out of reach of children and pets. If the OCV (Open Circuit Voltage) drops below 12.4 volts recharge.
There are a number of factors to consider when determining how often a battery needs to be replaced. These include vehicle type, region or climate, and driving habits. If your current battery performance is unsatisfactory, you may need to upgrade your battery to suit your particular situation and needs.
The most harmful elements to an automobile battery are heat and vibration. However, there are numerous other factors that can cause battery failure, such as: corroded cables and terminals, lack of electrolyte maintenance, sulfation, alternator/regulator malfunction, and electric shorts.
A car charging system is comprised of three major components.
A simple analogy for a charging system is to compare it to a garden hose with a spray nozzle and a bucket/receptacle. Water flows through a garden hose as does the electrical current to the alternator. As long as the water/current is flowing, the hose/alternator is producing electrical current to charge the battery.
The regulator, compared to the spray nozzle at the end of the hose, determines the amount of the electrical current released into the battery. The battery becomes the bucket/receptacle already filled with water. When water is removed from the bucket, the spray nozzle/regulator will open to allow water/electrical current to refill the bucket, or recharge the battery. Once the battery is completely recharged, the regulator will shut off the flow.
When jump starting a car it is important to make sure you shield your eyes and face from the battery at all times and follow these steps:
Yes! Deep cycle batteries are specially designed with denser active material and thicker plates to withstand deep discharge-recharge service. They are also reinforced by envelope and glass mat separators to reduce shedding of the active material and damage from the jolting vibration of a boat on choppy water.
Car batteries, on the other hand, use porous active material and thin plates so that high-amp energy can be quickly delivered for maximum starting power. Repeated cycling weakens the positive plates and makes the active material shed from the grids. Thus, in repeated deep discharge-recharge applications, the capacity of the car battery drops below desired levels in about 50 cycles. They are not built to withstand the heavy buffeting experienced by marine batteries. They are simply designed to do a different job.
A starting Battery can be likened to a “sprinter” and a deep cycle battery more like a “marathon” runner.
These batteries are designed to provide "deep cycle" power - making them very different from ordinary car batteries. Starting a car requires a high amount of energy for a short period of time (about 5 seconds). Only a small amount of the battery's capacity is used. Once the engine starts running, the battery is recharged quickly by the alternator, which carries the basic electrical load.
On the other hand, deep cycle batteries supply a relatively low amount of current for a long period of time. They are specially designed to power electric trolling motors and other electrical accessories in boats and RVs. Unlike ordinary car starting batteries, they can be run down and recharged (deep cycled) repeatedly with minimum loss of capacity.
When a car starting battery is deep cycled, it loses capacity very rapidly and in some cases has lost its useful capacity in 50 cycles (discharges and recharges) or less. These limitations make car batteries a poor investment when used for marine and RV deep cycle applications. A single deep cycle marine/RV battery will outlast 2-4 car batteries.
