A
battery supplies your engine with the necessary power it needs to
start. To generate this power, it relies on sulphuric acid
electrolyte and lead plates. A battery has 6 cells, each of which can
generate about 2 volts. So, in total, it produces around 12 volts of
electricity.
Along
with powering the starter motor, the car battery also powers the
ignition system. Also, any additional energy that other electrical
components need, which exceeds the alternator’s capacity, will be
supplied by your car’s battery.
Although
lead-acid batteries are quite reliable, you will need to replace your
battery, at best, every 4 years. When a battery approaches the end of
it service span, most often it causes a delay with engine start.
So, if
you are looking for a new car battery in Preston, consider
equipping yourself with the right know-how first to make a better
choice.
How
to select the right battery
Different
vehicles have different demands, which depend on their size,
components and performance. Here are a few factors you must consider
before buying car batteries.
-
Decide between standard flooded battery and AGM
-
Flooded batteries – Also known as wet batteries, are the most common battery construction. Here, the electrolyte is in a liquid state, and the lead plates remain submerged in them. Wet batteries come cheap, but requires regular maintenance, such as electrolyte top ups. They will also need frequent recharging as they hold charge for less amount of time.
-
AGM batteries – These are speciality batteries. AGM stands for absorbed glass mat, which refers to the fibreglass mesh inside the casing that holds the electrolyte. These batteries are highly impact-resistant and have the least internal resistance.
They
boast lesser charging time as well. With all these benefits, they are
expensive and cost more. They are easy to store and do not tend to
accumulate sulphate residues. If you don’t drive daily, an AGM
battery is the choice for you, as they hold their charge longer than
other batteries.
-
Consider size and layout
You will need to consider the physical dimensions and the terminal
locations, which depend on your vehicle’s make and model. Size and
layout are usually based on your engine type and vehicle design.
-
Choose appropriate cold cranking amps
CCA is a rating system that the battery industry uses to define its
ability to supply an engine with the necessary amount of power in
cold temperatures. It is the number of amperes a 12-Volt battery can
generate at -17° C while maintaining a minimum voltage of 7.2 volts.
-
Battery reserve capacity
You can identify this factor on the battery body as RC, short for
reserve capacity. Reserve capacity is an indication of the duration a
battery can operate without any recharging. Amp hour is a similar
specification, but it refers to the amount of energy a battery
stores.
A
thorough engine diagnostics in Preston from a reputed auto
garage will enable the technician to understand your vehicles power
requirement better and recommend you with a battery of appropriate
specification.
Top
auto garages such as Preston Tyre Bay sell batteries suitable for all
kinds of vehicles. They also provide services such as engine
diagnostics, brake repair and tyre repair.
