What happens if you use the wrong size car battery? Placing the wrong battery size to your vehicle may create changes in the flow of currents. For example, you set a larger battery size to your car; the difference in current may cause spikes and surges that could damage the computer onboard or the panel for the fuse.
What makes a battery go bad?
Deep discharges, heat, vibration, fast charging, and overcharging all accelerate the “aging” process. Approximately 50% of premature car battery failures is caused by the loss of water for normal recharging charging due to the lack of maintenance, evaporation from high under hood heat, or overcharging.
How do you tell if a car battery has a dead cell?
If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. If the battery is fully charged (according to the battery charger) but the voltage is 12.5 or less, the battery is sulfated. Sulfation is the natural byproduct when the battery discharged.
What happens if you have a dead cell in your car battery?
Slow Cranking The shorted cell does not allow the battery to hold the required amount of direct current voltage. The starter draws lot of amps when starting the automobile. A bad cell decreases the amps considerably. Without all the amps required, the car will have trouble starting.
How long can a car battery last with a dead cell?
about six yearsBattery Life (and Death) A car battery should last about six years, but like most car parts, that all depends on how you treat it. Multiple discharge/recharge cycles shorten any battery’s life and using electronics in the car while the engine is the quickest route to a dead battery.
What causes a bad cell in a car battery?
A common cause of battery failure is acid stratification. The electrolyte on a stratified battery concentrates on the bottom, causing the upper half of the cell to be acid poor. This effect is similar to a cup of coffee in which the sugar collects on the bottom when the waitress forgets to bring the stirring spoon.
