More flat plates mean more surface area, which ultimately means more power.

Our Rating: 4.3 out of 5

Key Features

  • Approximate cost: $280 – $300
  • Weight: 42.0 pounds
  • Battery type: AGM
  • Thin plate pure lead technology
  • Deep cycle capabilities
  • Long service life

What Customers Are Saying

There is a small batch of customer reviews for the Odyssey ODP-AGM96R on Amazon. Two customers each gave the battery a 5-star rating, signaling they were pleased with the performance of the device. However, Odyssey batteries have been in the industry since 1996 and are known for their performance over more than 25 years.

#5 Optima D35 YellowTop

Car Batteries Buyers Guide

Knowing the difference between car battery types save you money in the long run and prevent you from purchasing something that either won’t fit your vehicle or won’t perform properly.

When selecting a battery, you may want to consider the battery type, size, and terminal location. Check your owner’s manual to determine the correct type of battery for your car.

Battery Type: Standard Flooded Vs. AGM

There are a number of battery designs, but the two most commonly used in automobiles are flooded batteries and absorbed glass mat (AGM) batteries.

  • Standard flooded: Also called a wet cell battery, this is the most common type of car battery. The battery is filled with an electrolyte solution and may need to be occasionally topped off with water. A flooded battery allows you to start your vehicle and use a relatively standard amount of onboard accessories.
  • Absorbed Glass Mat: An AGM battery contains fiberglass mats that absorb the electrolyte solution and is therefore considered a “dry” battery. AGM batteries are highly vibration-resistant, non-spillable, and maintenance-free. This type of battery offers a superior lifespan to standard flooded batteries and can handle large power demands.

Generally, AGM batteries are better because they last longer, perform better in cold temperatures, and require less maintenance. However, AGM batteries are also more expensive than flooded batteries, and your car may not need this type of battery.

If your car came with a flooded battery, you can upgrade to an AGM battery. If your OEM battery is an AGM battery, we wouldn’t recommend switching to a flooded battery.

Battery Size

Different automakers use different battery sizes depending on vehicle model or generation. Brands like Nissan, Honda, and Toyota tend to use different sizes than American manufacturers, but check your owner’s manual for the best option for your vehicle.

Terminal Location

The terminals on your battery connect the battery to your vehicle’s computer. There are different layouts for terminal locations and you need to be sure to select the correct layout for your vehicle so that it can be properly installed.

Starter Vs. Deep Cycle

Depending on your driving style and specific vehicle you drive, your car batteries have various demands.

  • Starter: This type of battery delivers a quick but large burst of power to start your engine. These batteries aren’t designed to withstand multiple discharge and recharge cycles like a deep cycle battery.
  • Deep cycle: This type of battery offers a consistent amount of power over a long period of time. It can be used to start your vehicle’s engine but is better known for its ability to handle multiple onboard accessories.

How To Replace A Car Battery

The longevity of any automotive battery varies based on your local conditions. Humidity and extreme heat or cold will shorten a battery’s lifespan, but they typically last anywhere from three to six years.

If you notice any of the following signs it may be time to replace your car battery:

  • Slow engine start/engine often fails to start
  • Check engine light
  • Dim headlamps
  • Electronics such as power windows and dash lights stop working
  • A rotten smell (corroded battery)

You can pay a mechanic to replace your battery for you, or save some money by replacing it yourself. Replacing a car battery takes some know-how and requires tools, but is not so difficult that only a mechanic can do it.

Safety: Batteries contain corrosive chemicals, so protect your skin by wearing appropriate gloves.

Disconnect the old battery: You’ll need to start by disconnecting the negative cable. This is typically black and is marked with a “-” sign. You’ll need a wrench to disconnect the cable, and the bolt size varies by battery and vehicle. Next, disconnect the positive cable, which is usually red and marked with a “+” sign. After you disconnect each cable, be sure to secure it with a cable tie to ensure it does not come into contact with metal.

Remove old battery: Your battery is likely secured by a metal bracket. Remove this bracket and pull the battery from the battery box.

Install the new battery: Slot your new battery into the battery box. Make sure that the terminals are free of corrosion and secure the battery in the same manner the old battery was secured.

Attach the terminals: Reconnect the battery cables, starting with the positive cable. After attaching the cables, you can also coat them with a layer of lithium grease to prevent corrosion.
