Why wont my vehicle start?
If the battery won't start your vehicle, you usually refer to it as "dead," even though that's not technically correct. A battery that's merely discharged - from leaving your headlights on or from a damaged alternator - can be recharged to its full capacity. But a battery that's at the end of its service life can't be recharged enough to restore it to a useful power level. Then it truly is dead, and must be replaced.
If the battery is discharged and not dead, you can jump-start it from another fully charged battery. About 30 minutes of driving should allow the alternator to fully charge the battery. But if the alternator or another part of the electrical system in your vehicle is damaged, the battery will not recharge and a mechanic or service station also will not be able to recharge it. So if your battery keeps discharging, have your electrical system checked before you replace it. What looks like a bad battery could be an electrical system problem. If you have a bad component in the electrical system, it will keep draining a new battery, and you'll be stranded again and again.
How do you know which battery is right for your vehicle? Here are some quick tips to help you make the right choice.
Check your vehicle manual for the original equipment manufacturers recommendations for:
-if possible Battery group size - the battery size that will best fit the physical dimensions of your vehicle. Many vehicles can accommodate more than one group size.
-if possible Cold cranking amps (CCA) - CCA is critical for good cranking ability. It's the number of amps a battery can support for 30 seconds at a temperature of 0 degrees F until the battery voltage drops to unusable levels.
-if possible Reserve capacity (RC) - helps to power your vehicle's electrical system -if the alternator fails. It identifies how many minutes the battery can supply ample power without falling below the minimum voltage needed to run your vehicle.
In general, both CCA and RC are the higher the number the better. However, if you live in a cold climate, the CCA rating should be an important consideration in choosing a battery. Conversely, if you live in a high heat climate, you don't need as much CCA.
How does a battery work?
A battery stores electricity for future use. It develops voltage from the chemical reaction produced when two unlike materials, such as the positive and negative plates, are immersed in the electrolyte, a solution of sulfuric acid and water. In a typical lead-acid battery, the voltage is approximately 2 volts per cell, for a total of 12 volts. Electricity flows from the battery as soon as there is a circuit between the positive and negative terminals. This happens when any load that needs electricity, such as a radio, is connected to the battery.
Most people don't realize that a lead-acid battery operates in a constant process of charge and discharge. When a battery is connected to a load that needs electricity, such as the starter in your vehicle, current flows from the battery. The battery begins to be discharged.
In the reverse process, a battery becomes charged when current flows back into it, restoring the chemical difference between the plates. This happens when you're driving without any accessories and the alternator puts current back into the battery. As a battery discharges, the lead plates become more chemically alike, the acid becomes weaker, and the voltage drops. Eventually the battery is so discharged that it can no longer deliver electricity at a useful voltage.
You can recharge a discharged battery by feeding electrical current back into it. A full charge restores the chemical difference between the plates and leaves the battery ready to deliver its full power.
This unique process of discharge and charge in the lead-acid battery means that energy can be discharged and restored over and over again. This is what's known as the cycling ability in a battery.
In an AGM battery, the special absorbent glass mat (AGM) soaks up all the acid in the battery, providing high cyclic stability. This enables the battery to be repeatedly charged and discharged without any loss of performance.
What cause battery failure?
Battery Application and Installation
The battery is not being used in the application for which it was designed
The battery is not sized properly for the application
The vehicle has excessive electrical accessories
The battery is not properly fitted into the vehicle
The battery cables are not clean
The battery cables have not been properly adjusted to fit the battery terminals
Battery Service and Maintenance
The vehicle’s electrical system has been repaired or altered
The vehicle has been stationary for a long period of time
The vehicle has been brought in from or driven in another part of the country for a long period of time
The battery tray was washed free of corrosion or electrolyte
Visual Inspection of Battery
Terminals show signs of having been hammered, twisted or driven down into the cover
Side terminals show signs of over-torquing
Container/cover shows signs of stress, damage or high temperature.
Ends of the battery are pushed out indicating plate growth
How can you check a battery’s performance?
Different usage applications will use different methods for evaluating a battery’s performance. Using a 20 hour rate or the 10 hour rate, you can use 0.05CA or 0.1CA to discharge the battery until the battery reaches a terminal voltage of 10.25 volts. You can then calculate the amp hours to see if the battery fits the specifications or not. For a 5 minutes rate, such as the HC1221W, you can use a 21 watts/cell discharge till the terminal voltage reaches a terminal voltage of 9.6 volts and then measure the discharge time to see if it meets the final specifications or not.
Is there preventative maintenance I can do for my battery?
The battery should be stored in clean, dry, ventilated, covered environment away from sunlight or heat source when not in use. Keep cell terminals and connectors free of dust and corrosion. Terminal corrosion may affect the performance of the battery and could present a safety hazard. Should corrosion be observed, disconnect the battery, unbolt and remove the connectors, and remove the corrosion by brushing the terminals and connectors with a dilute solution of baking soda and water (sodium bicarbonate). Reapply an anti-oxidizing grease before reconnecting and bolting the connectors. Always maintain proper records.Keep it after full charge and to recharge it every 3 or 6 months.
