Battery Upgrades

Last Updated: Jul 01, 2025

When that car battery finally gives up the ghost and it's time to replace it, GILBERT drivers have options. First, let's be clear that you should always get a replacement battery that meets or exceeds your vehicle's specifications. But you may have some special needs. When they first put the battery into your vehicle at the factory, they had no idea where it would end up over its life or how YOU would use it where you drive in AZ. That battery was chosen to meet the needs of a wide range of motorists. Replacement time is a good opportunity to talk to your service advisor about how you use your vehicle so you can get just the right battery.

An obvious criterion is where you live, whether in GILBERT or somewhere else. Cold starts require a lot of power from your battery. The colder the climate, the more power needed. This comes from a combination of cold sluggish oil and the slower chemical reaction within the battery itself when it is cold. If this sounds like you, talk to your service advisor Fleming's Auto And Diesel about a battery with more Cold Cranking Amps (CCA).

The next consideration for GILBERT drivers is reserve capacity. This is the number of minutes of reserve power the battery has under a particular load. If your driving is mostly short stop-and-go trips around GILBERT, your battery may not have time to fully recharge while driving. You may need to tap into those reserves to get started again. Also, modern vehicles have a lot of always-on systems that draw on the battery – things like the security system, remote sensors, and vehicle computers. These combine with the electronic entertainment system, sensors, heated seats and even chargers for phones, tablets and computers to put a fairly high load on the battery. Your service advisor Fleming's Auto And Diesel can give you advice on the reserve capacity you might need.

Most standard batteries are “wet-cell,” meaning they are filled with liquid battery acid. New Absorbed Gas Mat (AGM) batteries are “non-spillable” which makes them safer GILBERT . They also have a longer life span and greater cycle life than wet-cell batteries. GILBERT off-roaders like these batteries because their performance is not affected by steep inclines and odd angles. They are also well suited for GILBERT RV and boat owners.

Lastly, consideration for GILBERT drivers is warranty. Premium batteries come with a longer warranty. Warranties are typically either full-replacement (the battery is replaced if it fails within the warranty period) or pro-rated (a partial credit is given for the failed battery depending on how far into the warranty period you are when it fails).

When the battery is replaced, your friendly and knowledgeable Fleming's Auto And Diesel technician may need to recalibrate some accessories such as power windows and sunroofs. Also, some vehicles may need to have the battery registered into the engine computer.

Your Fleming's Auto And Diesel service advisor can help you know how to decide which battery is right for you and your vehicle.
