How to Select the Right AGM battery for your Cadillac Vehicle

When it comes to choosing the best battery for your vehicle, there are a few factors to take into account:


By battery freshness, we mean how recently the product was manufactured. You should never buy a battery that’s older than six months from the date it was manufactured. You can always find the date of manufacture on the battery, which consists of a number and a letter. The letter stands for the month of production.


Short for cold-cranking amps, the CCA refers to a battery’s ability to produce a current in cold temperature. The higher the CCA of a battery, the easier it will start your car in winter, especially if you live in a region with cold climate.

Reserve Capacity

The reserve capacity refers to the number of minutes that a fully charged battery at normal temperature will discharge 25A of current until the battery becomes ineffective. A good AGM battery should have a RC of at least 100 minutes.


Because an AGM battery can be quite expensive, you will want to purchase it as least often as possible. So make sure you look out for how long the battery could possibly last. You shouldn’t sacrifice lifespan for high CCA.


It’s also important to consider the warranty as it dictates the possibility of getting a free replacement in the event that a new battery is defective. A good battery warranty should be at least 36 months.
