FAQs – Frequently Asked Questions



1) How to read the date code on the AC Delco battery? 


You will find the warranty date code on the top label of the battery. P or S is the first character. The succeeding two digits will represent the month, the next number is the year, and the fourth is the manufacturing plant. For instance, P 094N, which means it was manufactured in September 2014.


2) What is not included in the AC Delco 36 month warranty?


Almost all of the ACDelco batteries offer a 36-month limited warranty period. However, there is an exemption. The warranty does not cover damages due to negligence, improper installation, charging system failure, accident, freezing, or abuse.


3) How long does a Diehard battery last?


Majority of northern US batteries has an average shelf life of 56 months. Those manufactured in the south has an ordinary life of 43 months. If you are driving most of the time in places with cold climates, choose the lead-acid batteries.


This type of battery is not recommended in warm climates as it increases water loss and sulfation — the car battery lifespan range from 2 to 5 years.


4) What is more critical, CCA, or Reserve Capacity?


The Cold Cranking Amps test is the needed amps to crank an engine for thirty seconds at zero degrees Fahrenheit. Because of gear reduction starters, smaller motors, and low viscosity engine oil having the right amount of Cold Cranking Amps is needed but not too much. Getting more CCA will not start up your car quickly.


The Reserve Capacity test, on the other hand, is the time a battery will last with the headlights on or at 25 amp draw. With the increased electronics in a vehicle, Reserve Capacity is more vital as compared to having too much CCA.


Conclusion 

Choosing an ACDelco battery for your vehicle is a good move. The brand is known for quality batteries that last longer. In buying the battery, you need to evaluate the power your car needs by getting to know your engine.


After reviewing the above ACDelco batteries, we find 49AGM Professional AGM Automotive BCI Group 49 Battery as the best. It has high CCA and Reserve Capacity, which is needed by most vehicles today.
