A Semi-Truck on the road

On the hunt for the best semi-truck batteries, you'll find a lot of conflicting advice. Should you choose AGM batteries or traditional lead-acid batteries? Which are the best semi-truck batteries: deep cycle or starting batteries?

There is so much information out there that it can be really difficult to find the best battery for your diesel truck. Luckily, there are some handy tips to make the search a bit easier.

AGM vs. Traditional Lead-Acid Batteries

First of all, let's talk about AGM batteries vs. traditional lead-acid batteries. There are some misconceptions that need to be cleared up.

Absorbent glass mat batteries (AGM batteries) are not a completely different type of battery. AGM batteries are a subtype of lead-acid batteries that are sealed. The act of sealing these batteries means that they won't spill during an accident and that they can be installed at awkward angles.

You cannot, however, test or charge your AGM battery the same way you would a traditional lead-acid battery. Because AGM batteries have a lower internal resistance than flooded batteries, older analyzers won't work on them. You'll need one of the newer models that have an AGM mode.

Likewise, you can't use your traditional charger for your AGM battery. These batteries need to be charged slowly, and overcharging them can kill them completely. Also, don't mistake your alternator for a charger - use a proper charger if your battery dies completely.

Deep Cycle vs. Starting Batteries

Next, we need to talk about deep cycle batteries vs. starting batteries. Despite the difference in name, these batteries actually work exactly the same way, using exactly the same chemistry. The difference lies in the plates.

A starting battery, which is the type of battery used in cars, uses thin plates which provide a surge of energy over a short period of time. This surge turns the engine over to start it -- thus the name starting battery -- and then the alternator takes over the work of powering the car.

A deep cycle battery, on the other hand, can only provide about half the amount of surge that a car battery can. These batteries are designed to slowly discharge over a long period of time. This kind of battery drain would ruin a car battery, but the thick plates on deep cycle batteries are designed to perform this way, making them the best semi-truck batteries.

How We Reviewed

In reviewing the best semi-truck batteries of the year, we took many factors into consideration. We aggregated reviews from professionals as well as everyday truck users. We looked at the comments made by customers and clients of these battery companies.

It's important that the list of the best semi-truck batteries comprise only those batteries that will perform consistently, last a long time, and do the work efficiently that they are designed to do. Every battery on this list meets these specifications, so the following is arranged in no particular order.
