Car & Truck Batteries
Unlimited of Chanhassen, MN we can help you choose the
right battery for your vehicle and lifestyle. Our staff can safely and
professionally install your battery and get you back on the road.
Even if you have the most meticulously maintained vehicle on the road,
without a well maintained battery, your vehicle may not start or even
allow you access to the vehicle. From power door locks to auto start
systems, today's vehicles rely on correct voltage and clean connections to
allow today’s technology dependent vehicles to perform and take you to
electrical system powers everything from the ignition and fuel systems to
accessories such as your radio, headlights and wipers. The electrical
system is, in turn, powered by the engine. The following is a brief
overview of the electrical system that makes transportation possible:
When your car's engine is
off, the battery provides the required power to the rest of the system,
as well as during start-up (cranking). It also supplements the power
from the charging system during periods of high demand. Composed of a
series of lead plates submerged in a 35% sulfuric acid/65% water
solution, your 12-volt battery houses a chemical reaction that releases
electrons through conductors, producing electricity which is then
channeled into your vehicle's electrical system.
charging system is the life force of your vehicle's electrical system, It consists of three main components: the belt-driven
alternator, various electrical circuits, and a voltage regulator. The
alternator supplies power to the electrical system and recharges the
battery after your car has started. Just like it sounds, the voltage
regulator controls the voltage, keeping it within the operating range of
the electrical system.
This system consumes more
electrical power than any other component in your car. The starting system
consists of three components which work in tandem: the ignition switch,
the starter relay or solenoid, and the starter motor. The ignition
switch controls the starter solenoid, which activates the starter motor.
The starter motor then turns the engine until your car starts.
Your vehicle's battery primarily
helps to start the engine. However, it also stores energy generated by
the alternator, and runs the secondary electrical systems or additional
components in your vehicle. To help you take care of your battery we
recommend these simple preventative maintenance measures each time you
pop the hood:

THE AVERAGE CAR BATTERY
LIFE: WHEN IS IT TIME FOR A CHANGE?
Car batteries provide a vehicle’s life force.
We rely on them to get our cars started and keep them running, to power helpful onboard accessories and even to charge
electronic devices. The average car battery life can be anywhere from three to five years, but the exact time any given
battery needs to be changed depends on a number of factors.
Let’s Get Chemical - Most cars on the road today have 12-volt lead-acid batteries under the hood. There are a few
variations on this, but the basics remain the same. An automotive battery is actually a group of cells in a series — 6
cells producing 2.1 volts, to be exact. Each cell is made up of two types of lead plates (lead and lead-dioxide) submerged
in a sulfuric acid solution and connected across to the next like plate, forming two poles — one positive and one
When they are connected through a circuit, a chemical reaction takes place that moves electrons across the plates to
produce an electric charge. The battery becomes discharged as electrons move from one plate to another but can be
recharged by sending them back to the first. Over time, however, the chemical reactants will become used up, and it will
no longer be possible to produce enough voltage for automotive needs.
Positives and Negatives - The average car battery life is influenced by many variables, but even under perfect
conditions, it will eventually degrade because of its chemical makeup. The two biggest culprits responsible for shortening
a battery’s lifespan are surrounding temperature and driving habits.
As they are usually located under the hood with the engine, batteries are already subjected to high levels of heat, but in
warm climates during the summer months, the extreme heat can begin to discharge the battery in as little as 48 hours. This
is because heat works to evaporate liquids inside the battery and causes internal damage that ultimately shortens the
You might have experienced difficulty starting your car in the winter, too — that’s because cold temperatures make it more
difficult for the battery to produce the initial burst of energy to get the engine turned over, and the cold thickens
engine oil, which doesn’t help either. However, this alone does not shorten the battery lifespan the way heat does.
Unfortunately, climate is not a factor you have much control over. But the second important variable you do: driving
habits. Stop and start driving, or driving under 20 minutes on a regular basis, uses the battery’s power without giving
the alternator enough time to recharge, thus draining it to very low levels repeatedly and shortening its life expectancy.
Time for a Change - There are a number of telltale signs that will alert you when the end is near. Look out for
sluggish cranking or onboard electronic components acting erratically, such as flickering headlights. Check the battery
every six months or so for swelling and/or a weird smell like rotten eggs, which means there is something wrong internally
and it must be changed. Some vehicles have a warning light on the dashboard to give you a heads up that something is
All batteries eventually go, so keep a lookout for signs when you reach the three-year mark and listen to what your car is
telling you. Replacing the battery is an easy fix that prevents big headaches down the road, so it’s worth your while to
stay on top of it.
Here's how it works:
Turning the ignition causes a small amount of current to pass through
the starter relay, causing a stronger current to flow through the
battery cables and into the starter motor. The starter motor cranks
the engine, forcing the piston to create enough suction that draws a
fuel and air mixture into the cylinder. The ignition system creates a
spark that ignites the mixture and your engine starts.
