Buying guide

If you need a battery replacement, we prefer you go for an ACDelco battery. They are the best in the business. Before you grab a power unit for your vehicle, there are few important factors that you must take into consideration. Let’s take a look. 


Batteries come in varying sizes. This is where the battery group comes in. Your car will have compartments in the hood that supports a particular battery group.

The advantage of sealed batteries is that you don’t need to change the water, like flooded batteries. AGM batteries are sealed and don’t require maintenance, which adds to your convenience. We, as experts, prefer sealed batteries over flooded ones.

Reserve capacity

The more the reserve capacity the better it will carry the loads. Batteries must have decent reserve capacity to back up the electronics of the vehicle. Even when kept idle, the reserve capacity helps the car to power up whenever needed. If the alternator fails, reserve capacity comes in handy and saves the day. Like the ACDelco group 48 in our list, it has a good enough reserve capacity of 120 minutes.

Cold-cranking amp

You must buy a battery that has enough CCA. Cold-cranking amp powers up the engine during harsh weather such as low temperature and all. Don’t overlook this factor, because you never know what weather condition you might run into. Give your battery a chance with a high cold cranking amp, such as the ACDelco Gold 94R battery which offers up to 850 CCA.


Batteries are electrical equipment and might fail anytime due to different issues. You should buy a battery that has warranty backup, replacement warranty.

You don’t need to add water to ACDelco batteries. They have AGM properties and are sealed, meaning they take care of themselves. 

What Is More Critical, CCA, Or Reserve Capacity?

A Cold-cranking amp refers to the ability of a battery to start at a cold temperature. Some batteries have low CCA and some high. If you are driving at a lower temperature, CCA is supercritical. A higher cold cranking rating works like magic on chilly temperatures. Whereas Reverse capacity helps to power up your vehicle’s electrical system even if the alternator fails.
