ACDelco Batteries: Impressive Features

Solid Construction

Going for a battery with a solid exterior and interior build might sound like common sense knowledge but when you’re shopping for batteries, it is something you would want to check out.

When it comes to batteries, you’ve got flooded and sealed lead-acid types. The sealed lead-acid batteries or AGM batteries should be your first pick. These batteries make use of a suspended electrolyte which makes them last longer than flooded types. They can be mounted in any position and are maintenance-free as you won’t have to check for water level or monitor them for spills and leaks.

In addition to that, AC Delco batteries come with a polypropylene case with a reinforced exterior that ensures the battery can withstand vibrations and road shocks without giving out. AC Delco batteries also come with a lead calcium expanded grid. This gives the batteries an edge over others. With this feature comes benefits like corrosion resistance and low self-discharge.

Multiple Applications

AC Delco batteries are designed for multiple uses so you won’t have to spend extra to purchase different batteries. YOu can use their batteries for starting your vehicle, high cycle uses, dual-purpose starting, and deep cycle applications. You will also find an inbuilt hydrometer that indicates the state of charge of the battery. You won’t have to worry about overcharging this battery thanks to its solid design.

Excellent Service Life

While you may have to change your vehicle batteries twice or more depending on certain factors, this doesn’t mean you shouldn’t go for batteries that won’t give you many years of service. AC Delco batteries are designed to run for many years and come with long warranty coverage to prove this point.

These batteries are fitted with a liquid-gas separator that helps to extend its lifespan along with heat-sealed covers that prevent electrolyte contamination. If you’re going for AC Delco car batteries, you will find a handy flame arrestor feature. This is designed to prevent explosions due to sparks outside the battery and it also helps to reduce acid leakage. Without charging, these batteries have a shelf life of up to 12 months thanks to their calcium grids.


AC Delco AGM batteries come with different warranty covers which could be as long as 36 months. In some of these battery models, you will only be covered for 18 months. While the long-term warranty cover is a good sign, you should take note of what is covered and what is not.

AC Delco battery warranty will cover every occurrence except:

  • Batteries damaged due to negligence, charging system failure, accident, abuse, freezing, or improper installation.
  • Incidental consequential damages such as loss of time, loss of vehicle use, or inconvenience
  • Labor costs for removing and installing the battery
  • Cost incurred for recharging the battery or renting batteries or vehicles

Some Downsides of AC Delco Batteries

Not the Best for Areas with Hot Climate

One of the biggest worries of car owners is using their cars in areas with harsh climates. While most people would be worried about the freezing cold which is the common culprit of many car battery issues, the blazing heat is also a problem. In hot areas, your battery would last between 2 to 5 years and this is a big problem as your warranty won’t kick in. AC Delco batteries may be great for most applications, but if you live in an extremely hot area, you might want to try out the toughest model, which is also the most expensive or check other alternatives.

A Bit Pricey

AC Delco batteries are great, but they are by no means the least expensive. To get them, you would have to pay a little more than what you would with flooded batteries which is a big investment on your part. The good news is that your investment is totally worth it as these batteries are designed to last you way longer than flooded types. They will also deliver more superior performance to get your vehicle started quickly every time.
