How long should a Battery
last?
Battery life is influenced by type of driving, how
long the battery spends at below full charge, how often heavily
discharge, under-hood heat and of course quality of the battery.
Cause of low battery charge are; short trip driving cycles, long periods
of not driving or charging system problems.
Battery Ratings
Cold Cranking Amps (CCA)
Indicates how many amps a battery can deliver for 30 seconds and
maintain at least 7.2 volts at 32 F.
Cranking Amp (CA)
Similar to CCA; Cranking amps is a measure of the number of amperes a lead acid
battery at 32 degrees F can deliver for 30 seconds and maintain at least 1.2
volts per cell. (CA ratings are more commonly used in climates where
temperatures rarely drop to 0F.)
Reserve Capacity (RC)
Reserve capacity is the time in minutes that a new, fully charged battery
will deliver 25 amperes at 80 degrees F and maintain a terminal voltage
equal to, or greater than, 1.75 volts per cell.
What it Means
A higher CCA will give you more raw starting power and a high RC will
help keep a battery going longer when an alternator fails or something is
left on such as the headlights. Some batteries will have a high CCA but a
small RC, which can leave you stranded if you leave your door open for a
while, or let the car sit for a week.
Never use a battery with a lower capacity rating than is recommended by
the manufacturer, not only will it fail early, some very cold morning it
may leave you sitting.
A 4 year battery may be at 50% in 2 years, always buy a five or six year
battery.
Why they go Bad
Heat and vibration are the biggest battery killers,
heat causes a battery's positive plate grids to corrode more rapidly and
can cause the battery plates to warp and short out. Many
other factors can also cause battery failure, such as: corroded cables and
terminals, sulfating, alternator/regulator malfunction, and electric draws.
Anytime a battery is discharged (goes dead) it shortens the battery's
life.
Jump starting
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:
Charging
If a battery is discharged rapidly, it should be recharged rapidly.
If it’s discharged slowly, it should be recharged slowly on a trickle
charger. (This could take 8 – 10 hours on a fully discharged battery)
Note: Overcharging a battery will damage the internal plates and shorten
battery life.
Recycling
Batteries are 99% recyclable and are filled with lead and acid. Please
recycle your batteries!
