Battery Replacement signs, Slow Engine Crank: When you attempt to start the vehicle, the cranking of the engine is sluggish and takes longer than normal to start.

Clicking sound when you turn the key or Multiple warning light on in the dash .

To guarantee a long service life, the Battery must be checked, serviced and maintained as described in the service  manual.

The Battery  supplies the power to start the engine. The Battery  also acts as a power reserve for the entire vehicle electrical system.

while cranking, to supply additional current when the demand is higher than the alternator can
supply and to act as an electrical reservoir. Batteries are rated in cold cranking amps.This
represents the current the battery can produce for 30 seconds at 0 degrees before the battery
voltage drops below 7.2 volts.

Below are some additional terms you may see when trying to find the right battery for your Vehicle.


the sulfuric acid solution used as the electrolyte in a battery.


the part of a battery made from two dissimilar metals and an acid solution. A cell stores chemical

energy to be used later as electrical energy.


batteries are the principal energy storage devices for hybrid electric vehicles (HEVs). Desirable attributes of high-power  batteries for HEV applications are high-peak and pulse- specific power, high specific energy at pulse power, a high charge acceptance to maximize regenerative braking utilization, and long calendar and cycle life. Developing methods/designs to balance the packs electrically and thermally, developing accurate techniques to determine a battery's state of charge, and developing abuse-tolerant  batteries, and recyclability are additional technical challenges.


the electrical current that passes through the battery to restore it to full power; to fill, or bring up  to

the specific level,


the system that supplies electrical power for vehicle operation and recharges the battery.


the number of cranking amperes that a battery can deliver in 30 seconds at O"F ( - 18"C).


difficulty of starting an internal combustion engine in cold weather because of gasoline, which evaporates more slowly when it is cold; oil, which gets thicker in cold weather; and the chemical reactions inside the battery, which progress more slowly in cold weather.
