The actual frequency will depend the climate, region and road condition also the driver. If you're disappointed with the battery life you get and your car's electrical system is in good operating condition, you should upgrade

Diesel (compression ignition / fuel injected) engines do require significantly more starting energy (time and power) .

Some four - cylinder engines do require more power than six - cylinder engines. The starter normally
turn at a higher r.p.m. and you have fewer chances to "fire" per revolution. However, many other
factors come into play such as compression ratios, starter motor design, vehicle option, etc. Always
consult the owner's manual or battery application guide for the minimum rating for the application in
question .

Before removing the old battery, carefully note the location of the positive battery terminal and mark the polarity on the positive cables. In this way you can avoid installing the new battery reversed. Remove the "ground" terminal first. This precaution is to avoid damage to wiring and the battery by accidental "ground" with tool.

In removing or tightening the hex nut on the bolt of clamp terminals use the proper size end wrench. Use an end wrench to remove cables from side terminals, stud terminal or "L" terminals .

Inspect the cradle for possible damage caused by loss of acid from the old battery. Be sure the cradle and its hold downs are mechanically strong and free from corrosion. Corroded parts and cable terminals may be cleaned with water, to which some household ammonia or baking soda has been added, by scrubbing with a stiff brush. Corroded steel parts should be dried and painted with acid - proof paint. Do not paint battery terminals. Clean and tighten the "Ground" connection. Tighten starter relay and connections.

In general, longer warranty periods are assigned to higher capacity batteries that is, batteries with more or longer plates and hence higher CCA and reserve ratings. You can not, however, relate the warranty period to actual service life, except in comparative term, i.e., batteries with longer warranties will, on average, live longer than those with shorter warranty periods, given the same conditions (vehicle application, driving pattern, climatic region, vehicle conditions, etc).

For example, the life of a 500 CCA battery in 300 CCA application will be better than the life of the same 500 CCA battery (with the same warranty) in a 500 CCA application
